| refs/tags/r2015.1.21 | r2015.1.21 | 20cd972 | Release 2015.1.21 Contributors: Albert Cardona, Andrew Champion, Tom Kazimiers Features and enhancements ------------------------- General neuron tracing: - A new radius editing option has been added that propagates from the current node root-ward to the previous node with an undefined radius (exclusive). Here undefined is taken to be a negative radius, since though the column default is 0 Django initializes it to -1. Miscellaneous: - Users need now to confirm the closing of the last stack. Bug fixes --------- Tracing overlay: - A label is now hidden when the mouse hovers over it. Note that this only works for one label at a time, so it is not effective for overlapping labels. A robust solution would require more expensive event propagation over label elements. - Fullscreen on OS X Safari should now work, too. - Nodes and arrows are now drawn in order: lines, arrows, nodes, labels - Fix bug that could occur during radius propagation when the previous node already had a radius defined. - Fix mouse handlers of node and error drawing, which were broken by adding ordered drawing. Synapse clustering: - A long-standing error has been fixed where a few nodes where added to an undefined cluster. Group graph: - The root node computation has been fixed. - Listing edge synapses now also works with split grouped neurons. 3D viewer: - Make synapse clustering fetch synapses properly (like it is done in the Group Graph). | 22 January 2015, 20:22:43 UTC |
| refs/tags/2021.12.21 | 2021.12.21 | b74f51f | 2021.12.21 ========== Contributors: Chris Barnes, Albert Cardona, Andrew Champion, Stephan Gerhard, Sanja Jasek, Tom Kazimiers Notes ----- - The version requires PostgreSQL 12. If you also want to upgrade PostGIS, update PostGIS first and run ``ALTER EXTENSION postgis UPDATE;`` in every existing database in the cluster that should be upgraded. For docker-compose setups this database update is performed automatically if `DB_UPDATE=true` is set for the `db` container (watch the Docker output). CATMAID's documentation Docker has more information. If a replication setup is in use, the database configuration changes for Postgres 12. CATMAID's replication documentation explains what needs to be done. In Postgres 12, JIT compilation is available to the planner by default. We found that being more conservative with the use of it helped a few common queries (like the tracing data field of view). We set the required minimum cost of JIT use to 1,000,000 in ``postgresql.conf``:: jit_above_cost = 1000000 - If R extensions are used, make sure to use R 3.6. On Ubuntu this can be made available by first installing the official R PPA repository: sudo gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-key E084DAB9 sudo gpg -a --export E084DAB9 | sudo apt-key add - echo "deb https://cloud.r-project.org/bin/linux/ubuntu xenial-cran35/" | sudo tee -a /etc/apt/sources.list And second update the package index and update the local R setup: sudo apt-get update sudo apt-get install r-base r-base-dev mesa-common-dev libglu1-mesa-dev \ libssl-dev libssh2-1-dev libcurl4-openssl-dev cmtk This also requires updating all installed R packages. In all likelihood this requires executing "manage.py catmaid_setup_nblast_environment". - The default downsample factors for a stack without explicit factors defined, changed slightly: if you relied on the automatic creation of downsample factors for image stacks, make sure the changed behavior still works for you or enforce the previous configuration with an explicit specification of downsample factors. Previously as many zoom levels as needed were created to map the image size in a quadratic fashion per level onto a 1024x1024px tile. Instead of hard-coding the 1024px, the minimum tile size defined in the mirror set is used. Without any mirrors, no extra zoom levels will be assumed. - The recommended python version is now 3.8, although support for 3.6 is maintained. - A virtualenv update is required. Features and enhancements ------------------------- Notes widget: - This new and simple widget can be used to take notes either only for the current project, shared across all projects or globally visible for all users. The last option is only available to admin users for writing. Use the "Open Widget" dialog to open it using the "Notes" keyword. Publication widget: - This new widget makes management of publication related annotations easier. It lists all annotations that annotated with one of the publication annotations defined in the Settings Widget in the Publication section. Each of them represents a publication for the widget. The export options for each one of them can now be configured through the table. Project management widget: - This new widget allows superusers and users with can_administer role in a project to edit user and group permissions for this project. This interface is easier to find and manage then the admin view and allows for more granular admin permissions. It is also useful to share own spaces (own copies of projects) with other users. - The widget allows to define for both user and groups the following permissions: can browse (read), can annotate (write), can administer, can import, can queue, compute taks, can write through API, can fork - Clicking any checkbox will store the value right away. - If a user has "can_administer" permissions in a project, they can edit the project title and project description (comment) in the second tab. - If a user has "can_administer" and "delete_project" permissions in a project, the project management widget allows to delete the current project. This is mainly useful for personal spaces, in which users typically have delete_project permissions. - The "User data permissions" tab allows to configure user level edit permissions (who is allowed to edit who's data). - The "Project token" tab allows project admins to view existing project tokens ("invitation codes") available for a project. For each generated token, the table allows to copy both the token itself as well as an invitation link using this token to the clipboard. If a user opens an invitation link, they will automatically apply the token. Anonymous users are asked to log in first. - As admin user in a project, it is also possible from to manually change skeleton IDs from the "ID updates" tab. This is only allowed if the new ID isn't used already. Also, if the new ID is a new maximum ID number, all new IDs will be automatically be larger than this ID. This functionality is also available as the back-end managment command catmaid_change_skeleton_id. Skeleton ID change management command: - Just like the Project Management functionality explained in the last paragraph, the management command catmaid_change_skeleton_id can be used to change skeleton IDs (and optionally neuron IDs) from the command line. Link widget and deep links: - This new widget allows users to create persistent deep links into the dataset using an alias, allowing for friendlier URLs of the form `<catmaid-url>/<project-id>/links/<alias>`. The stored parameters are the same as for regular deep links, with most of them being optional. - Like with fully parameterized URLs, features like layout, widget settings and loaded skeletons can be used. - Links can be marked private, making them only accessible (and listable) by the creator of the link. - An optional message can be stored with the link and is shown to the user when the links is opened. - The context menu for creating different types of links moved from entries in the Layouts menu to its own menu that is shown when hovering the mouse cursor over the "URL to this view" link. The first menu entry is new and opens a link creation dialog, similar to the Link Widget's 'Add link' dialog. Neuron renaming: - There is now a new neuron renaming dialog, which allows a search/replace renaming workflow for many neurons at the same time. This can be launched through the "Rename" button in both the Neuron Search widget and the neuron lists of the Neuron Navigator (e.g. neurons with a particular annotation). - The dialog supports simple find/replace, but also regular expressions including capture groups and presents live previews. Neuron search: - Neuron search: add option to show meta data columns (cable length, number of nodes, creation time and last edition time) for neurons. - Removal tools for annotations are now opt-in, i.e. not shown by default. To enable them during annotation display, click the "Show removal tools" checkbox. - The optional annotation column has now the option to only show annotations with a particular meta-annotation. This meta-annotation can be configured in the input field in the table column header. - The CSV export comes now with a header row to make clear the first column is a neuron ID. - The CSV export includes now the skeleton ID as well and will export metadata like cable length, if metadata display is enabled in the UI. - Expanded elements (e.g. annotations) are now sorted correctly within their expansion group. This also fixes the out-of-order expansion display. - Escape underscore and percent sign properly. They were treated as wildcards before. Connectivity Matrix: - The new buttons "Save JSON" and "Open JSON" can be used to save the row and column skeletons, including groups and widget settings. - The loading speed has been improved significantly. - With the new "Link type" selector in the Main tab it is now possible to show the connectivity matrix for other link types (like desmosomes or gap junctions). The selected link type is also respected by the CSV export. Layouts: - New layout menu item: "Copy URL to view with layout". This will create a URL to the current view like the link button on the right hand side of the second toolbar, but with a layout spec included. It will open all widgets in the new CATMAID like in the current one. This includes skeletons, their colors and widget configurations by default. A second menu entry with the "(no skeletons)" suffix allows to create link with only the layout and no skeletons. And a third menu entry with the suffix ("no widget settings)" allows to copy only the layout plus skeletons, without any widget configuration. - New layout menu item: "Copy current layout spec". This will copy the layout specification of the current view to the clipboard. This can be useful when constructing URLs to specific views. - Widgets in layouts can now optionally specify a list of skeletons to load. This is done by adding the `skeletons` parameter: "skeletons": [16035815, {"id": 16035701, "color": "rgb(0.5,1,0.2)"}] The list of skeletons can consist of skeleton IDs and/or optionally objects that can also specify a color in terms of common CSS definitions. - The Selection Table can now receive an options parameter from the layout initialization. If it contains a list of skeleton IDs like this, then selection table will load this automatically: options: {"skeleton-ids": [16035815, 16035701]} This has to be added to the URL manually at the moment, by adding it to the selection table config part in the layout spec. Volume manager: - The table of filters applied to input neurons for volume creation has now a new "Actions" column. At the moment this includes a "Remove" link for each filter. This makes it easier to try different filters without removing all other filters - Annotations can now also be removed from volumes if "Show removal tools" is enabled. - For new node filters during volume creation, the merge mode can now be selected, i.e. whether additional filters will be combined using OR or AND. - The new "Import from CATMAID" tab allows users with import permission to search and import volumes/meshes from other CATMAID projects, both local and remote. Volumes can be searched by name and annotation. - Don't show removal options by default. It happens generally rarely that one wants to remove volumes, especially in the skeleton innervation tab. To reduce the risk of accidental removals (even though a confirmation dialog is shown), removal buttons are now only shown if the "Show removal options" checkbox is enabled in the Main tab. - The connector listing for a volume will now include unlinked nodes. - The checkbox to show the removal tools is now colored red, to make it easier to see how to remove volumes. Graph widget: - Add options to configure the edge text outline size and opacity. The options area available from the properties dialog. - Grouping with undirected edges like desmosomes won't lead to multiple edges between the same groups anymore. - Ungrouping groups with members having non-synaptic links (e.g. desmosomes) doesn't lead to an error anymore. - Remember selected link types in local widget state storage. - Applying node filters works now correctly and only removes an edge if both source and target node are not allowed according to the filter configuration. It is now also possible to use additional subgraphs (e.g. axon/dendrite split) with filters applied. Connectivity widget: - Larger input and partner sets can now be displayed. - Make node filter test consistent with filter application in the Graph Widget. A connection is now valid according to the selected filters if it uses a connector node that is linked to a node allowed by the node filters. The node filters are still only applied to the query skeletons. This makes the filtering numbers consistent with the Graph Widget. 3D viewer: - The new tab "Volumes & Geometry" contains now all settings related to volumes, landmarks and point clouds. This makes the "Volume settings" tab a little less overloaded. - The View tab has two new controls to control the sensitivity of both camera zoom and position change when using the scroll wheel without an with the Alt key, respectively. - Connector restrictions (View tab) now offer a new option: show only connectors with a specific tag. If selected, a dialog will ask for the desired tag and will hide all connectors that aren't tagged with it. - For both in-widget and exported animations a duration time in seconds can now be specified. When enabled and an animation is played in the 3D Viewer, the duration will just stop rotation and any other ongoing animation after the specified time in seconds. If enabled for an animation export, it determines the total length of the video, regardless of history or rotation settings. - The history export in the animation export doesn't use a frame number input field anymore and the "Complete history" checkbox has been removed, too. Instead, the duration input can be used. If the duration input isn't enabled, the complete history is exported. - Both in-widget and exported animations don't need to have rotation anymore. A new checkbox can be used to disabled rotation. Without rotation the camera will just keep its position at the moment. - Zoom behavior of the camera can be animated both for in-widget and export animations. When enabled, a speed of nm/sec can be defined for the camera with which it will move towards its target. This setting is both available in the animation tab and the export dialog. - A scaled version of the Strahler analysis shading mode has been added. The scaling factor can be adjusted in the Shading parameters tab. This is mainly useful for visualization. - The PNG export dialog allows now to select whether the background should be transparent. - The "Focus skeleton(s)" button in the Main tab will now focus the center of mass of all skeletons loaded in 3D, if no skeleton is active or the active skeleton is not loaded in the 3D Viewer. - The current view is now part of the saved state/settings. This is used as initial view when used in a URL or when saved through the 'Save settings' button in the panel opened by the window icon in the widget title bar. - The "Shading" tab features now an input text field that allows to change the location of the hemispheric light source. The checkbox "Lock light to camera" next the location input allows to automatically set the light location to the camera location, causing the light to come always from the viewing direction. - The export "Connectors as CSV" 3D Viewer button now also exports the spatial coordinates of each connector. The coordinates are represented with three additional columns. Skeleton history widget: - Skeletons to query can now also be appened through the common skeleton source controls. - Now past skeletons with different skeleton IDs than the query IDs are displayed as well as part of the graph. - Edges show now more information in their labels: the number of nodes added as well as the number of nodes deleted from the transition of nodes from skeleton A to skeleton B. - By default skeleton refreshs keep all nodes in-place. To try a different version of the current layout, use the "Relayout" button. Neuron navigator: - Neuron widget nodes (like the active neuron display) show now also the initial creator of the neuron and the initial creation time. - The textual representation of neurons now follows the global settings. - The neuron list filter input now remains focused when typing. The neuron table should also update quicker initially. - The pagination in neuron lists is fixed and does work on the first attempt now. Previously it took a second click to actually jump to a page. - Sorting annotation lists works again for all columns. - The annotation filter/search term survives now refreshes of the currently displayed data (e.g. by clicking on the name in the navigator path). - The select-all checkboxes in neuron lists now actually select all neurons across all pages. This allows for bulk annotation, deannotation and deletion. Morphology plot: - Radial density can now be shown also for desmosomes and gap junctions. Treenode table: - The new node type "Adjacent to gap" will show all nodes that are in a Z slice marked as broken or adjacent to it. Such nodes are marked with an additional "G" in the node type flags. Docker: - The new environment variable CM_SERVER_SETTINGS can be used to define any settings.py based setting. A valid Python code sting is expected, \n can be used for newlines. - Asynchronous tasks can now also be run inside the Docker container. Celery and RabbitMQ are run by default, but can also be run in separate containers (see CM_CELERY_BROKER_URL, CM_CELERY_WORKER_CONCURRENCY and CM_RUN_CELERY Docker environment variables). - Maintenance tasks are now automatically executed inside the Docker container if Celery is enabled. This happens around midnight UTC by default, but the time zone can be adjusted using the CM_CELERY_TIMEZONE environment variable. For instance, use "America/New_York' for US east coast time. This way, maintenance tasks can be moved to whenever local midnight is. - CORS header are now enabled by default and allow also authentication. This is useful to allow other web services to access a Docker back-end directly. This can be disabled by setting "-e CORS_OPEN=false" with e.g. "docker run". Vagrant: - We now support a Vagrant configuration for setting up a full replicable development environment with minimal effort. - This is distinct from the Docker image, which is for creating an ephemeral production environment. - See the relevant developer documentation page for more details. Data sources: - A new tile source has been added: Neuroglancer Precomputed data, with ID 14. This image block source works very similar to the N5 tile source. At the moment only non-compressed and non-sharded image volumes are supported. In order for the voxel space coordinates to match between CATMAID and Neuroglancer, if the Neuroglancer dataset defines a voxel offset, the respective CATMAID stack needs to have its zoom-level zero voxel offset defined in the stack meta data in the admin view, e.g. `{"voxelOffset": [-3072, -3072, 0]}`. - A second new tile source is available: CloudVolume based tiles, generated by the back-end. While slow for many users, it is a convenient way of make neuroglancer volumes available to CATMAID if they aren't supported by the Neuroglancer Precomputed source. It works better for a small set of users and smaller block sizes. The new tile source has ID 13. Administration: - User profiles can now include a "home view", which is a reference to the preferred data view for a particular user. When a user signs-in, this data view is displayed. If none is set, the default data view is used. - External accounts can now be used to sign-in to a CATMAID instance (if enabled) using OAuth2. The documentation has details on how to configure this. This can allow users with e.g. an existing Orcid ID or GitHub account to sign-in to a CATMAID instance. If enabled, there is now a menu displayed when hovering the mouse over the "Login" button in the upper right corner. - Like every other new user, users created this way can be in default user groups (`NEW_USER_DEFAULT_GROUPS` setting) and the default tool visibility settings apply as well. - If new users are created, there is now also a user group created with the same name as the new user's username. This group can be used to manage edit permissions the user's data. If groups shouldn't be created automatically, set the `NEW_USER_CREATE_USER_GROUP` to `False` in the settings. - Project importer: YAML data can now also be pasted into a text box for project import, just like JSON data. - The basic scripts/tiles/tile Bash 2D tiling script now by default creates as many zoom levels until the whole image fits on one tile (rather than two like before). It also accepts now an additional optional argument with which the number of zoom levels to generate can be specified. Moreover it also provides an option to specify an output directory and knows the common default value for the overview size (192px). - System check widget: more information regarding a potential transaction ID wraparound has been added to the database section. - User account creation now supports confirmation emails and welcome emails. The User Accounts section of the manual has more details on this. - Superusers will now see an extra menu item in their user menu (upper right corner user name): Instance configuration. It opens a dialog which currently presents two options: whether to show local and external login controls. Tracing data export: - The management command catmaid_export_data supports now the specification of export options for tags, annotations and connectors per publication. To tell the exporter which annotations/publications are allowed to carry these settings, the "--settings-meta-annotation <annotation>" can be provided to the exporter. For instance, assuming the provided <annotation> is "Published", then all annotations that are annotated with "Published" are checked for additional annotations that specify explicitly whether to export tags, annotations and connectivity. The following annotations are respected: "export: no-connectors", "export: no-tags", "export: annotations", "export: no-annotations", "export: no-connectors", "export: intra-connectors-only", "export: intra-connectors-and-placeholders", and "export: intra-connectors-and-original-placeholders". - The --conector-placeholders and the --original-placeholder-context options have been removed. Instead the --connector option can now have four different options: false, intra_connectors_only, intra_connectors_and_placeholders, intra_connectors_and_original_placeholders. This provides the default configuration if no publication specific options are provided. - With the help of the new --allowed-tags-only parameter it is possible to limit the kinds of tags that are exported. Without this parameter, all tags are exported. If --allowed-tags-only is provided without arguments, a standard set of known tags is included (uncertain end, posterior end, ends, anterior end, not a branch, really ends, uncertain continuation, soma, microtubules end, out to nerve). Alternatively, such a list can be provided as argument to this parameter. - In case all (minus exclusions) skeletons should be exported, now also all annotations are exported if requested by the user. This wasn't the case so far and in this mode no annotations were exported before. Tracing data import: - The catmaid_import_data management command will now truly update only project wide data if --update-project-materializations is provided (as opposed to selective updates for the imported data). Before, the summary information was still computed instance wide. - The new option --update-instance-materializations can now be used to update the summary table information instance wide. Import/export widget: - A new 'Import log' tab will show users with import permission a list of their imports. Double clicking entries moves the few to a representative location. - So far, if no name was provided in the UI, the imported neuron would just have no name. Now the user is asked whether the import should be canceled or if the file name should be used as default name, if no name was provided by the user. - If multiple SWC files are imported and a name is provided, an incrementing numeric suffic will be added to each name. - After one or more SWC files have been imported, there is now a list of links displayed at the bottom of the widget. Each link is a successful import and, when clicked, selects and moves to the respective skeleton. - The NetowrkX JSON graph export is now in networkx 2.x format, rather than in v1.x format like before. The main difference is that start and target nodes of an edge are now defined explicitly by ID rather than an index. Project statistics widget: - Subsections will now show more clearly when they are still fetching data. - A new data overview section has been added to the bottom of the content. It shows currently the total cable length of skeletons in the project along with the total number of treenodes and connectors. Selection table: - A minim review percentage can now be used as a filter using the new numeric input in the name column header table cell. - Duplicate skeleton IDs are now ignored in a CSV file import. TrakEM2 import managmenet command: - The new catmaid_import_from_trakem2 management command can be used to import data from a TrakEM2 XML file in a similar fashion as the scripts/export/export_from_trakem2.py script. It can however import in addition TrakEM2 AreaList objects and connectivity. - It generates meshes and skeletons by first generating a marching cubes based mesh from the AreaList (using TrakEM2 functionality), then using Blender to remesh that mesh to get a watertight manifold. This mesh is then first imported as a triangle volume into CATMAID and then it is skeletonized. The skeletonization can be done in different ways, by using skeletor or stl2swc. The latter seems to generate better skeletons at the moment, but might require a bit more setup time. TrakEM2 based node transformation management command: - The new catmaid_update_tracing_data_using_trakem2_xml management command can be used to transform all spatial data in a project based on the transformations defined in a TrakEM2 XML file. This includes - This command uses Java and Fiji directly using pyjnius, which needs to be set up separately. The management command will expect the PYJNIUS_JAR environment variable to point to it (or provided using the --pyjnius parameter). Data views: - Add the options sample_image, sample_mirror and sanmple_slice to the front-end based "Simple project list" data view. These options behave like in the other data views. - If more than one data view is available, users can now select a home view by clicking the home icon in the 'Home' menu in the upper left corner. Upon next reload of the page, this makes the respective data view the default one the users sees. - The icon to create a link to a data view changed to a more common chain icon. - A click on the Home button in the upper left corner will now bring the user to their home view (if defined), otherwise the global default data view. - The data view menu (Home button) will now highlight the currently active data view. - A new front-end based data view type is available: resources and spaces. It organizes projects in resources (read-only) and spaces (write) and indicates this with different colors. - The front-end data views now support the option "with_controls" (false by default). If enabled favorite projects are indicated with a little star, which also allows to toggle the favorite state by clicking on it. Only for admins visible, right next to it, there is a pencil button to open a dialog to edit the project title and description. If a project token was used to make a project visible, the controls will also show an option to revoke a previously used token. This will undo all permissions added by the token. Cropping tool: - A new radio button in front of both the top and the bottom Z index sliders allows users now to choose whether the link the displayed Z slice to either the top or the bottom of the copping box. This makes it easier to visually confirm top and bottom of the bounding box. - The ARTIST TIFF tag is now used to store meta information about the cropping task: the min and max coordinates of the bounding box as well as the resolution. ImageJ/Fiji read this particular tag. Landmark widget: - Landmarks can now be exported from the widget as CSVs - Skeletons in the list of displayed transformations are now shown using their Neuron Name Service based name, rather than only a skeleton ID. This works for local and remote skeletons. Tracing layer: - Shift + Delete will now attempt to delete a node even if it is not in view. This is mainly useful for deleting nodes in previously visible broken sections. - It's now possible to add the personal tag set to newly created nodes. Both the personal tag set and the new option can be configured in the Tracing section of the Settings Widget. - Fallback to WebGL 1, if WebGL 2 is not available or can't be initialized properly. In these cases image block rendering (e.g. N5) will be unavailable. (Applies to image layer as well) Tracing tool: - Node distance measurements (icon in tracing tool bar) are now allowed also between nodes of different skeletons. In this case only the straight line distance will be displayed. Both the straight line distance and the path distance will be displayed for nodes of the same skeleton. - Centering on the active node reads now the active node only once all present tasks (like node creation) are done, which makes centering on newly created nodes using 'A' center reliably on the new node rather than the parent. - The position and ID input box on the right side of the second tool bar accepts now also location triplets that are delimited by space or tabs. Miscellaneous: - The dialog to add new annotations (F3 key) accepts now multiple annotations as input, separated by commas. To include a literal coma, use baslash to escape it: \, - Regular view links (URL to this view): virtual nodes can now be referenced. Only the parent and child ID are looked at when selecting a virtual node, which means URLs keep working if parent or child location of a virtual node change. - The initial loading of client settings is now faster, because it performs fewer requests. - Each stack viewer will now show the project name by default along with the stack and mirror name in its title bar. This can be adjusted in the "Stack view" settings of the Settings Manager. - Layer settings like opacity, blending more or filters can now be stored as part of the regular settings and can be defined for the regular scopes like in the Settings Widget (e.g. session or project). These settings are stored per layer type and source reference (e.g. stack ID). In order to save, restore and clear those settings, there are now three new buttons at the bottom of each layer that supports settings storage. - The minimum zoom level can now be configured in the Settings Widget using the "Min zoom level" control of the "Stack view" section. - Stack viewers can now have an optional layer offset configured. Accessible through the Layer Controls, it allows users to configure one or more Z steps from a stack space Z coordinate z1 to z2, that will cause an offset of the current location in XY if the move from z1 to z2 is performed by the user (e.g. by pressing comma or period). This can optionally be constrained by a location and a radius. Generally, this helps working with registration problems e.g. at TEM gaps. - Client-side widget settings aren't stored by default anymore, if the widget is closed. The former default caused a lot of confusion, especially with the 3D Viewer. If widget settings should be stored, they have to be stored explicitly using the "Store settings" button in the widget settings panel, available by clicking the window icon right next to the widget title. - Client-side widget state can now optionally store UI interaction information like the camera location / details in the 3D Viewer. In the widget settings panel (window icon in widget title bar), this can be done through the "Save settings & UI state" if a widget supports this. Deep links will include the UI state by default. - Auto-completion should now be faster by displaying only 15 filtering results by default. Clicking on the "..." entry will expand the auto-completion list to its full length. - Volume widget: box volumes can now be created also based on the active skeleton's bounding box. - Connector table: a search filter is now available for the table that allows filtering across all columns. - Global Search (looking glass icon): Neuron names are now properly displayed using the general naming service. This makes the naming respect global naming patterns. - Connector selection: a search filter is now available for the table that allows filtering across all columns. - Settings widget: adding a remote CATMAID instance without supplying an API key will now make CATMAID try and get the API key of the remote anonymous user. This makes it easy to add publicly accessible CATMAID instances, because it is now enough to provide the URL of the remote CATMAID instance. Additionally, hash characters (#) at the end of passed in URLs are now removed automatically. - The user registration form fits now the overall layout better and include first and last name as well as the email address. Also, a link to the user registration form is now displayed right next to the login link in the top right corner, if user registration is enabled. It also allows to optionally require users to accept a certain set of terms and conditions, which can be configured through the settings variables USER_REGISTRATION_CONFIRM_TERMS and USER_REGISTRATION_CONFIRM_TERMS_TEXT (disabled by default). - The overview image in the lower right corner of the stack viewer is now displayed by default. This behavior can be adjusted for users, projects and the whole instance in the Settings Widget. - Open window: a new button "Open with active skeleton" makes it quicker to open a new widget with the active skeleton loaded. - Log/history tables: the relevant data is now fetched in parallel and doesn't block the rest of CATMAID anymore. - Layer settings: the color transform filter matrix input elements use now background colors to better indicate the meaning of rows and columns. - Key shortcut widget: the content is now refreshed when the selected tool changes. - If Caps-Lock is enabled, users now see a warning by default if they press down any key. This can be disabled in the Settings Widget. - Client settings that are stored in the browser's local storage are now properly namespaced so that they work with multiple instances on the same server. - The new settings.py setting `PROJECT_TOKEN_USER_VISIBILITY` allows to constrain the users that are visible to non-superuser users. If enabled, only users that share knowledge about the same project tokens can be seen. - Export management command: the new option --public-deep-links allows to export public deep links of the selected projects. Bug fixes --------- - Cropping tool: if a single pixel past the start of a new image tile represented part of the outer boundary of a cropping area, this part was rendered only as black pixels. This is fixed now. - Cropping tool: fix error on tool destruction when clicking on Home link - Graph widget: fraction edge labels work again. They produced an error before. - Graph widget: edge color updates of non-synaptic links works now properly. - Graph widget: fix node width/height setting. - 3D viewer: PNG exports can now be transparent again. - 3D viewer: the default settings for orthographic mode and control lock are no correct (i.e. in accordance with what has been saved as default). - 3D viewer: the scale bar is now properly initialized if orthographic mode is stored as default view. - 3D viewer: fix camera movement using the mouse wheel. - 3D viewer: the volume list is now also updated if a volume is deleted. - 3D viewer: the landmark group list is now updated when landmark groups are added or deleted. - 3D viewer: the volume visibility controls are now correctly enabled if a volume is made visible from another widget. - 3D viewer: prevent accidental double loading of volumes, if the first attempt didn't finish before the second. - 3D viewer: fix saving a loaded volume twice in a saved state or URL. - 3D viewer: mesh transparency is now handled in a more robust fashion. - 3D viewer: landmark group event handlers are now correctly unregistered, fixing an error in the Landmark Widget showing if a 3D Viewer was closed. - 3D viewer: history animations can be created again. - Volume lists (drop down menus) are now automatically refreshed if a volume is added, updated or removed. - Volume manager: the "Invert" checkbox for new filter rules for input skeletons during volume creation is now position properly. - Volume manager: the colors used for showing result volumes from an innervation query in a new 3D Viewer are now computed correctly so that they match the listing colors. - Node filters: default values for extra options like merge operation, skeleton/name filters or invert, are now correct on repeated filter creation if these options were changed for the first filter. - CSVs imported into the skeleton selection widget may contain nonexistent skeleton IDs, as intended. - Skeleton bulk updates like splits or joins should now be faster on setups with spatial change events disabled (default). - Connectivity widget: the rendering of large sets of input skeletons is now much faster. - Connectivity widget: showing a list of displayed links ("List links" button) is working again. - Connector list: shows now neuron names rather than skeleton IDs and can optionally include them in exported CSVs as well. - Neuron search: row highlighting for the active skeleton works now again for the whole row and registers deselection properly. - Neuron search: the active skeleton is now highlighted as soon as it part of the result shown in the table. Before, the row of the active skeleton wouldn't be highlighted after a search and only upon new selection of a skeleton. - Tracing data importer: The catmaid_import_data management command was not update edge data for project-wide materialization updates if there were no connectors imported. This if fixed now. - Tracing tool: a tracing data mirror server can now also be used with authentication. - Tracing tool: the "More tools" menu is now properly closed when a remote data source is selected. - Tracing tool: the mouse cursor icon is now initialized correctly. - Remote tracing layers: mouse bindings are now correctly updated when a remote layer is added. Before this could sometimes lead to mouse clicks not been caught in the remote tracing layer. - Skeleton import API: new annotations are now added to existing annotations by default, rather than overriding them. This can be changed by setting the replace_annotations parameter to true. - Stack viewer: fix inconsistent state when removing copies of stack layers. - Docker: when the container is stopped, all processes are now gracefully stopped as well. I.e. the database will be notified about an imminent shutdown, etc. - Layouts: subscriptions, skeletons and options are now now properly loaded from tab nodes in layout specs. - Tracing data export: management command: connector tags are now exported properly. Before in some cases inconsistent data was exported where either connectors or tags where wrongly referenced even though they were not included in the export. - Split/merge dialog: both annotation lists (one for each partner) maintain now a height of 50% in the dialog and don't cause enlarging the dialog with long lists. - Neuron navigator: require less neuron name updates when updating the active skeleton display. - Node filters: the "Pruned arbor" filter works again. - Neuron search: row highlighting for the active skeleton works now again for the whole row and registers deselection properly. - Connector list: can now display connectors without links. - Measurements table: "N presynaptic sites" column includes now by default also presynaptic connectors that don't have any postsynaptic link. To restore the previous behavior, the "Include half links/synapses" checkbox can be unchecked. - Navigator tool and sub-tools like Tracing tool: the Z slider is now properly hidden if the image data set has only one section. API changes ----------- Additions --------- - POST `/{project_id}/neurons/rename`: Rename multiple neurons at the same time. - GET|POST `/{project_id}/skeletons/summary`: Retrieve meta information like cable length or number of nodes for skeletons. - GET `/accounts/anonymous-api-token`: Get the API token for the anonymous user. - POST `/{project_id}/neurons/all-skeletons`: Map a list of neuron IDs to the skeleton IDs that model them. - GET `/{project_id}/`: Get project details like the title and comment. - POST `/{project_id}/`: Update the project title if the user has admin permissions in the project. Modifications ------------- - `GET /{project_id}/transactions/`: Now accepts the optional parameters user_id and type to further constrain the result. Type is a transaction label string, e.g. 'skeletons.import'. - `POST /{project_id}/skeletons/import`: Now accepts the optional boolean parameter replace_annotations, which can be used to remove all existing annotations if an existing neuron/skeleton is replaced with force=true. - `POST /{project_id}/graphexport/json`: The returned graph export is now in networkx 2.x format, rather than in v1.x format like before. The main difference is that start and target nodes of an edge are now defined explicitly by ID rather than an index. - `POST /{project_id}/skeleton/connectivity_matrix`: The new parameters row_relations and col_relations allow callers now to specify the relations used to connect two skeletons for each side. They default to "presynaptic_to" and "postsynaptic_to". Deprecations ------------ None. Removals -------- None. Maintenance updates ------------------- Modifications ------------- - `POST /{project_ids}/skeletons/in-bounding-box`: Returns now also unlinked connectors by default. To only get linked connectors like before, pass in `only_linked = true`. -----BEGIN PGP SIGNATURE----- iQJIBAABCAAyFiEEcCprn1Qmc4Ga52d87CoFhulcmScFAmHBuLgUHHRvbUB2b29k b28tYXJ0cy5uZXQACgkQ7CoFhulcmSezOhAArc78Pq/mKETuUjP+2f5p+eoVdwRv 6TIfp73w9vCPcplCzs1BzSM0eeQmPQ9QU8fTIeINV7GfFOcZ1wgNJo9kTTJJgY7h EoRAqOVOaxKajJjkpWNQvaEwJ2uMNv+fNub+06wugyDvhwOUPXFUcnFxdaG56OyV klIjhZntzKNEjAho70Iug9YCvvat7cF0Xqewc6zMQ9zxNrDK9CHrWrSSk8blf7Gn ZTobZJzVa0SntMs+vVmP3F/7Ov4+W1yHyiW0KMhRohUdDOJkl5LGdXOIDvd3cjGl MJWBKnqRTbMVf6RdK3fvk9jEqoEyoNrZ1h+rNidu3hVcKpEs7+lQMV1qA3r2nus/ OOYNfrgmQoQoORM3Oi1ONND5BUxNmjVDDJDFORXBIooJSUXUSe5CTwifnnyXFrmB RjmpDXN1ePtAyq2KPLDvVbLXISkv2HqryDTnllpmlirZOVLV/mW2cSPM1FpeO5AM IT9IoqgcJ6kcfBOD3QNVdijX7DE5kCw4YdYrBYGz9v6V1OOu14ow8RwEKMI7JeKq 3NvbkUGMj2AKeKgYKj9AnwvdikJOZrbaMzXlyD/3UumnLgQzr+guIA3CofUpV6oI hlQR2EYYl8ZUc6wGj1bQ26xKrQbdaOrVqybooxkfbSC2LrBf9ArAvA5/J8MRPNy8 2JqboG6bklyM5Vs= =mGzj -----END PGP SIGNATURE----- | 21 December 2021, 11:21:28 UTC |
| refs/tags/2020.02.15 | 2020.02.15 | 4e39b4a | 2020.02.15 ========== Contributors: Chris Barnes, Andrew Champion, Stephan Gerhard, Pat Gunn, Tom Kazimiers Notes ----- - Python 3.5 is not supported anymore. Use Python 3.6, 3.7 or 3.8. - Postgres 11 and PostGIS 2.5 is required, Postgres 12 and PostGIS 3 is recommended. If Postgres needs to be updated, update directly to Postgres 12. If both needs to be updated, update PostGIS first and run ``ALTER EXTENSION postgis UPDATE;`` in every database. For docker-compose setups this database update is performed automatically. If a replication setup is in use, the database configuration changes for Postgres 12. CATMAID's replication documentation explains what needs to be done. - A virtualenv update is required. Before you start it, please remove some packages that are not needed anymore first: pip uninstall asgi-ipc asgi-rabbitmq - If ASGI was set up before, make sure to install channels_rabbitmq or channels_redis (depending on what yous use). The older asgi_rabbitmq and asgi_redis packages aren't supported anymore. This also requires an update of the CHANNELS_LAYERS in settings.py. The channels_rabbitmq documentation for an example: https://github.com/CJWorkbench/channels_rabbitmq/. This variable isn't defined by default anymore. Therefore you likely have to replace any `CHANNELS_LAYERS[…] = …` with something like `CHANNELS_LAYERS = { … }`. The new format is (use custom credentials on any production system!): ``` CHANNEL_LAYERS = { "default": { "BACKEND": "channels_rabbitmq.core.RabbitmqChannelLayer", "CONFIG": { "host": "amqp://guest:guest@127.0.0.1/asgi", }, }, } ``` Also, if supervisord is in use to manage CATMAID process groups, the main Daphne process needs an adjustment: instead of calling `daphne` with the `mysite.asgi:channel_layer` parameter, use `mysite.asgi:application`. A complete supervisord entry would then look something like this: ``` [program:catmaid-daphne] directory = /home/catmaid/catmaid/django/projects/ command = /home/catmaid/catmaid/django/env/bin/daphne --unix-socket=/var/run/daphne/catmaid.sock mysite.asgi:application user = www-data stdout_logfile = /var/log/daphne/catmaid-server.log redirect_stderr = true ``` As last step, the supervisor entry for the `daphne worker` process has to be removed. New types of workers can be added, but are not needed in most cases. The channels documentation has more information on this. - GDAL v2 or newer is now needed. If your Ubuntu version doesn't support this yet, there is an official PPA: sudo add-apt-repository ppa:ubuntugis/ppa sudo apt-get update - The next version of CATMAID will require Postgres 12 and PostGIS 3. - The management command catmaid_populate_summary_tables is now known as catmaid_refresh_node_statistics. - When enabling and disabling both history tracking and spatial update events on startup, advisory locks are now used. This should make the startup of parallel CATMAID workers more robust. - The application of migrations 88-91 and 98-99 might take a while to complete, because they rewrite potentially big database table (treenode_edge, treenode, class_instance, and more). Therefore, make also sure that there is enough space available at the database storage location (25% of database data directory should be plenty). If no replication is used, setting the following Postgres options can speed up the process: `wal_level = minimal`, `archive_mode = off` and `max_wal_senders = 0`. Due to this database update data consistency and correctness was improved, because additional foreign key relationships have been added that were missing before. - Both `configuration.py.example` and `create_configuration.py` support now the option `catmaid_default_enabled_tools`, which defines the list of front-end tools that are enabled by default for new users. The following options are supported: cropping, tagging, textlabel, tracing, ontology and roi. By default the tracing tool is now enabled for new users, because it seems in many setups users want to have this enabled by default. - Back-end errors result now in actual HTTP error status codes. Third-party clients need possibly some adjustments to handle API errors. In case of an error, status 400 is returned if an input data or parameter problem, 401 for permission problems and 500 otherwise. - On startup, CATMAID will now test if the output directory is accessible as well as if its expected folder layout is present. If expected subfolders are missing, they will now be created. - Python code is now linted by flake8. The config is fairly relaxed (see .travis.flake8), but contributions which do not conform with the selected rules will fail CI checks. Features and enhancements ------------------------- Permissions: - If data is imported by a user, e.g. from a remote CATMAID instance, this user has all permissions over the imported data. If data was imported or created by someone else, the regular rules apply: permissions are granted if the user is creator, superuser or has permission over the data's creator. If user A has permissions over user B's data, user A will also have permission to edit user B's imported skeletons. This is done in order to be able to maintain the original creator and editor data of the imported data, should it be available. Node filters: - Binary split: a new toggle labeled "inclusive" allows to decide whether to include the split not in an upstream sub-arbor (default: true). CLI importer: - Performance improvement: only the skeleton summary entries of the imported skeletons are now created. - Only update treenode edges and skeleton summary if treenodes were actually imported (rather than e.g. only volumes). - Add --auto-name-unknown-users option, to automatically generate names for users that are not available from an import, but referenced in it (by ID). CLI exporter: - The new --annotation-annotation option allows to specify a meta-annotation that all exported annotations need to share transitively. If for instance all all top-level annotations that should be exported are annotated with "exportable" and "--annotation-annotation exportable" is used, only annotations from those annotation hierarchies marked as "exportable" will be exported. Without this option, all annotations are exported. - If users should be exported, also export users of volumes. Project statistics: - Requests to the back-end our now performed in parallel, resulting in faster loading times. - It is now possible to configure how many largest neurons should be displayed as well as an optional name pattern. - The user/time action table will now also list imported nodes and imported cable length. These values are subtracted from the corresponding regular counters. If "Include imports" is unchecked, the same information that was displayed before this commit is shown, i.e. the regular node count and cable length field include the imported data. Tracing tool: - The tool bar button to refresh caches has been replaced with a button to open a context menu titled "More tools". The context menu has an entry to refresh cashes and a list of tracing data in other projects. - Tracing data from other CATMAID instances (or other local projects) can now be added to the active stack viewer by selecting the respective remote project from the "More tools" menu item "Remote data". - To open a remote CATMAID instance at the same location as the current view, find the remote project in the "Remote data" section of the "More tools" menu, and click on "Open remote view". - The marker type used fore remote tracing data can be configured through the Settings Widget in the Tracing Overlay section, option "Remote node marker". A ring is used by default. - Merges will now by default respect the special annotation "stable". If a neuron is marked as such it will always win a merge and if both merge partners are marked "stable", the merge is canceled. This can be disabled by setting the project or instance setting "Stable join annotation" in the Tracing section of the Settings Widget to an empty string. The merge dialog will show a warning if stable merge annotations have any bearing on the merge direction. - Fast merge mode can now optionally be applied only to neurons/fragments with a particular name pattern (regular expression). This can be configured in the Fast Merge section of the Tracing section in the Settings Widget. - Alt + G will now select the closest node in the active skeleton. If no skeleton is selected, the globally closest node is select. Regular G works as before in the current section. - Skeleton splitting: if a skeleton sampler was in use, a split could so far only be successfully executed if the split node is within a sampler domain. This is fixed now and sampled skeletons can now be split upstream or downstream of a domain as well. If split upstream, the domain will be deleted, because it is part of the split-off fragment. - The default interaction mode (skeleton tracing, synapse dropping, select, move, import) can now be configured in the Tracing section of the Settings Widget. This interaction mode will be enabled when opening the Tracing tool. Tracing overlay: - The remote mirror CATMAID instance configuration is now taken from the central configuration, which can be edited in the "Other CATMAID instances" section in the Settings Widget. The "Read-only mirror index" settings is kept but refers to list elements in the central configuration list. - Joining two skeletons without confirmation ("fast mode"), will now attach an annotation to the resulting skeleton that references the merged in skeleton by name. The name of this annotation as well as the suggested reference visible in the confirmation dialog have the form "Merged: <neuron-name>". - It is now possible order loaded tracing data by skeleton size, both in ascending and descending order. This is useful with other node count limiting filters. The layer settings accessible through the blue/white box in the lower left corner of a stack viewer provides the "Data ordering" select box to change this setting. By default no ordering is applied. - When merging a fragment that contains a sampler, it can now be merged if the respective skeleton doesn't need to be rerooted. - Visibility groups can now use a generic node creator test that references the current user (logged in our anonymous). It is called "(self)" in the list of creators for all three visibility groups. This is useful to define visibility groups on the project or instance level that include a hiding pattern while guaranteeing that users see their own nodes. - Shift + Click on a remote node from a local node (or vice versa) will now bring up an import preview dialog which is used as a merge preview at the same time. Confirming the change will import the remote skeleton and merge it at the selected location, works with virtual nodes. Navigator: - Two new buttons and a text input field on the right side of the toolbar allow easier handling of locations: the first icon (the map marker) is a button to copy the current location of the center of the view in project (physical) coordinates. If clicked while the Alt key is pressed, stack (pixel) coordinates will be copied. Both modes will copy the coordinates in the form "X, Y, Z" to the clipboard. - The text input box allows to enter coordinates and other information. Pressing enter or clicking the angle brackets on its right side will make CATMAID try to interpret the text and act accordingly. The following interpretations are attempted: 1. `Project coordinates` of the form "X, Y, Z" and "X, Y". Parentheses and brackets are removed, 2. `Skeleton ID`, 3. `Location ID` (treenode, connector, etc.), 4. `Neuron ID`, 5. `Bookmark letter` from the bookmark system accessible through `;` and 6. Project coordinates from `CATMAID URL`. These are tested in order and whatever matches first, wins. - Additionally, particular interpretations can be enforced by using any of the following prefixes "stack:", "px:", "neuron:", "skeleton:", "node:", "connector:", "url:" and "bookmark:". It is possible to use only the beginning of a prefix, i.e. "stack: 1,2,3" is the same as "st 1,2,3". This will only try the referenced parser. It also makes stack-coordinate parsing available, which is otherwise not checked for. - Annotation lists show now also annotation IDs. Administration: - The catmaid_update_cache_tables management command accepts now a `--jobs=n` parameter, which allows it to run in parallel when set to values `n` larger one. By default a single process is used. This can speed up cache generation significantly. With the help of the option `--chunk-size=n` it is possible to define how many cells should be processed per CPU task. For large dataset it might be useful to raise the default of 10. - The catmaid_update_cache_tables management command accepts now a `--depth-step=n` parameter, which makes the update process reevaluate the number of grid cells to look at `n` times during a single run. For instance, if set to 2, the upper bound of cells to look at is reevaluated when the process is through with half the depth dimension. In larger datasets, this can speed up cache generation significantly. - The catmaid_update_cache_tables management command accepts now an optional ``--order`` parameter, which can be set to either "cable-asc" or "cable-desc". By default no order is applied. - The group list will now also show a sortable column containing the number of group members. It also provides a more useful filtering option on the right. Clicking "Only non-user groups" will now only show groups with a name that isn't a username. Additionally, it is possible to filter by a minimum and maximum number of group members. - Settings: add CLIENT_SETTINGS and FORCE_CLIENT_SETTINGS options so that an initial instance-wide client configuration can be specified. - Setup: the create_configuration.py script will now create backups of existing settings.py and django.wsgi files. Volumes: - Volumes have now their surface area and volume associated with them as well as whether they are watertight. This information is visible in the Volume Manager widget and can be recomputed on demand if needed, using the respective button in the action column. - The base unit used for the ara and volume columns can be adjusted using the "Reference unit" select box in the widget controls. Neuron Search: - Name queries can now be marked as exact, which prevents matching against parts of other names. This is ignored for regular expressions. - Name queries can now be marked as case sensitive using the respective checkbox next to the name field. By default name queries are case insensitive. - The search can now be further constrained to only skeletons that include at least partially imported fragments or to skeletons that are fully imported. Graph widget: - Node filters are now supported. Like in many widgets, they available through the funnel icon in the title bar. Only nodes that are allowed by the selected filters, can contribute connections and the graph. At the moment, this comes with a few caveats: if filters are in use, no subgraphs (e.g. axon/dendrite, synapse clusters) can be used. Grouping isn't available either and in addition, skeletons are removed from the widget if they don't comply with the filters. All this is likely going to chagne in future versions. - The "Nodes" tab has now three new buttons to hide, show and remove unconnected nodes. Show will nodes visible that have been hidden before. Removing nodes will remove the skeletons/nodes completely from the widget. - The node size specified in an imported .graphml file is now respected. This is useful if graph fine tuning (layout and node size) is done in other tools, like Gephi. Review widget: - The new tab "Synapse completeness" can list synaptic connector nodes don't have a presynaptic node associated with them as well the ones without a postsynaptic node. - The Skeleton analytics tab now also lists low confidence nodes/edges with a confidence lower than 4. The label of each entry shows the respective confidence value. Import/Export widget: - It is now possible to import neurons from other CATMAID instances. The "Import from CATMAID" tab provides tools to search remote skeletons by name or annotation. Imported neurons can automatically be annotated with a set of annotations. If no annotation are provided, CATMAID will add the annotation "Import" to imported skeletons. - A custom set of default annotations that will be added to imported skeletons can be defined through the "Default skeleton import annotations" option in the Settings Widget. At the moment, this is set to "Import" as well as "{source} upload {group}". The second annotation uses two optional placeholders, which are replaced by the skeleton import source reference and the user's primary group, respectively. Should no primary group be set, the username name is used. - The original ID and source URL of all imported skeletons is tracked. This allows the widget to display local skeleton IDs, if the remote ID has already been imported from the current source URL. - If the active skeleton is a remote skeleton (in a remote data tracing layer), it can now be imported by clicking the "Import active skeleton" button in the "Import from CATMAID" tab of the widget. Like the other import, this iwll first ask for confirmation with a 3D dialog. - The NRRD export can now use the JRC2018U (unisex) target template brain space as target. - The NRRD export can now export more than one skeleton at a time. All skeleton sources are now displayed. - The NRRD export will now by default create a Zip file if multiple skeletons are exported both in a synchronous and asynchronous export. - SWC imports can now have a user defined initial name. Neuron navigator: - The new button "Imported nodes" will list all imported treenodes for the displayed skeleton. - The detail view of an annotation will now list the time a neuron was annotated next to the listed neuron name. The last time this link was edited is shown as well. Both columns can be used for sorting as well. 3D viewer: - The new shading mode named "Imported fragments" will make only imported edges visible. The new coloring mode "Imported (green)" will highlight all imported fragments in green. - Stored views (View tab > Save view) are now shared between all CATMAID instances, not only between all 3D Viewers like it is done now. This means they are also persisted on the back-end and can be retrieved at a later point. - 3D viewer: the line width has now an upper limit of 25px to prevent crashes of the 3D viewer with larger values and many skeletons. - Desmosome links can now be displayed. The color assigned in the Settings Widget section for desmosomes in the Tracing Overlay is used here as well. Neuroglancer widget: - CATMAID now includes a copy of Neuroglancer that can be accessed at <catmaid_base_url>/neuroglancer - The Neurglancer widget allows to open an instance of Neuroglancer in a new window and its navigation (center location, zoom level) is synchronized with the navigation happening in CATMAID. An URL to a Neuroglancer instance containing the same dataset as shown in the CATMAID stack viewer needs to be provided. - The widget's info page has a step-by-step guide on how to use it for the FAFB dataset Treenode table: - The UI elements to select active filter options like node type, confidence or confidence operator now havea a colored background if an active filter is selected. This is useful to draw more attention to the fact that leaf nodes are selected by default. - Remote skeletons are now supported. They can be mixed with local skeletons. - A new column "i" represents whether or not a particular treenode was imported. This information is loaded separately, parallel to the regular information. Which, is why initially "…" is shown. If a node wasn't imported, the field is empty. If it was imported, "Y" is shown. Morphology plot: - Two new center computation modes have been added: Tagged node closest to root, Tagged node most distant from root. Both use the tag input field to the right of the center mode selector. Either pressing enter or Redraw after a tag change will recompute the plot. If no node is found with the respective tag, the root is used and a warning is displayed. - It is now possible to select the interpolation mode of the plot. So far the plotted data was always interpolated with a basis spline. This isn't necessarily what is required for a particular plot, e.g. if the sample values have to be intersected. To allow this, a drop-down menu with the following interpolation options has been added: basis spline, linear, cardinal spline, monotone, step before and step after. Spaces: - Users with the new "can_fork" permission have a new user menu entry in the upper right corner: "Create own space". This allows to create a personal copy of a project, without any tracing data. Miscellaneous: - The active project title is now shown in the window title. - There is a new menu item named "User info" in the menu displayed when hovering the mouse cursor over the user's name in the upper right corner. When clicked, it will show the basic information on a user: name, username, user id, primary group and color. - Projects can now be kept open if all last stack-viewers are closed. To not automatically close the open project with the last stack-viewer, uncheck the "Project closes with last stack viewer" option in the Settings Widget. - Neuron similarity widget: besides a regular arithmetic mean, the geometric mean is now an additional option for how to combine (normalized) forward and reverse scores. - Neuron similarity detail widget: make CSV export of object IDs and names configurable. - Retrieving review information is now faster for bigger skeletons. - Name search: the speed of search queries is now improved. - Selection table: the summary info button now shows also the number of imported nodes within the selected skeletons. - Neuron search: search fields will now expand if their content is bigger than the default size. Also copied fields don't contain the content of the source field anymore. - A CATMAID deep-link URL can now include the layout that should be displayed using the `layout` parameter. It takes a layout specification as it is used in the Settings Widget and the Layout menu. - The speed of bulk operations on skeletons has changed (e.g. splitting, joins, reroot). - Settings widget: it is now possible to clear both front-end and back-end settings through the "Clear settings" button. It will ask for confirmation and whether both front-end and back-end settings should be cleared. - The top toolbar of the web UI won't add line breaks anymore if only little horizontal space is available. The part of the toolbar that contains the widget buttons for the selected tool will shrink instead. Only elements that fit the available width are displayed there now. Invisible items are not a problem, because all widgets can be reached through the "Open Widget" dialog or Ctrl + Space. - Potential WebGL performance problems are now detected when stacks and stack groups are loaded. If problems are expected by the browser, a warning is shown. - Spatial update worker: cache cells are not queued for updates anymore if the source project of a spatial event doesn't have any caches. - Data views: add option "show_empty_projects" to simple project list data view. It is false by default and can be turned on to show empty projects, including the classification dummy project. - Project statistics: clicking the "User analytics" button with user selected will open the respective user analytics views for all of them (max. the first three). Bug fixes --------- - Connector list: dates are now display correctly. - Tracing tool: don't allow moving nodes in select-only mode. - Tracing layer: merged-in single nodes will now also have their name remembered as a new annotation in a join if their name doesn't follow the default pattern "neuron <number>". - Project importer: the UNIX "glob" filter pattern that can be used to filter imported projects is now also applied to imports from URLs and files. - Nblast widget: store tangent neighbor count specified in UI for scoring matrix imported from CSV. - Celery can now be restarted again without restarting all of CATMAID. - Connectivity widget: fix error showing when doing many subsequent Refresh button clicks. - 3D viewer: the handling of intersecting transparent objects has improved and works like expected in most situations. - Synapse plot: a missing skeleton source interface method was added, making it now possible to also remove skeletons from the widget. - Synapse plot: skeletons can now be added to the widget again. This was temporarily broken for CATMAID instances using a sub-folder in their URL. - Management command "catmaid_find_node_provider_config" to generate NODE_PROVIDERS configurations for the `settings.py` file:The default value for the "--orientation" parameter is now "xy". It was accidentally "xz" before. - Graph widget: pressing the Delete key with a node selected in an active Graph Widget will now ask for the removal of the node from the graph, not anymore whether the active node should be deleted completely. - Graph widget: showing fractions of inbound/outbound fractions of connections as edge labels works again. - Graph widget: refreshing a graph with undirected edges (e.g. sub-graphs like axon/dendrite split, desmosomes, etc.) doesn't lead to suddenly appearing arrow heads. - Graph widget: undirected links like desmosomes will now only appear once between two nodes. They would be shown twice before, once for each of the partners being the "source" or "target". - Graph widget: apply currently selected layout after graph update. This fixes occasional fall-backs to the force-directed layout. - SWC skeleton import: if `force = true`, treenodes of a replaced skeleton are now correctly removed on a successful import. - CLI Importer: creating unknown users manually works now as expected. - Node filters: the application of node filters with rules applied in an intersected fashion is fixed now and the filtered result of all skeletons is shown. - Spatial update notifications: only try to update the database configuration if the database isn't running as a database replica. - Synapse plot: fix read-out of settings input fields. - Connectivity matrix: don't raise an error in "fraction" display mode on a widget refresh (e.g. caused by a neuron name update). - Connectivity matrix: don't show error when enabling "fractions" display without neurons being loaded. - Connectivity widget: fix error caused by quickly refreshing the table successively. - Graph widget: fix error caused by quickly refreshing the graph successively. - Neuron navigator: fix name display after rename of neuron. - Neuron search: the tab key focus order within one widget is now maintained if multiple search windows are open. - Neuron search: sort results ascending by name by default and keep the sort order through table redraws. - Settings widget: the width of multiline select elements (e.g. annotation based neuron naming) is now adjusted automatically to fit the content. - 3D Viewer: fix skeleton vs. name CSV in "Synapses as CSV" export. - 3D Viewer: fix accidental hiding of soma node sphere when hiding radius meshes. This happened if the node tagged 'soma' wasn't the root node. Now the test for whether to hide radius meshes for a node now requires that the node isn't tagged with 'soma', which is more robust than root node alone. - Measurement table: fix CSV export for aggregated multi-fragment results. API changes ----------- Additions --------- - GET `/{project_id}/stats/cable-length`: Accepts now an optional 'name_pattern' argument that allows case insensitive pattern matching in the respective neuron name. If a '/' prefix is used, the pattern is interpreted as a regular expression. - GET|POST `/{project_id}/skeletons/validity`: Obtain a list of valid or invalid skeletons in a set pf passed in skeleton IDs. - `GET|POST /{project_id}/skeletons/from-origin`: Looks up skeleton IDs based on a set of `source_ids`, a `source_url` and a `source_project_id`.. - `GET|POST /{project_id}/skeletons/origin`: Gets origin information on a list of `skeleton_ids`. - `GET|POST /{project_id}/skeletons/import-info`: Gets information on which and how many nodes are imported in a set of skeletons. - `POST /{project_id}/annotations/query-targets`: Accepts now an optional boolean "with_timestamps" parameter, which is set to false by default. If set to true, the returned annotations will include their creation_time and edition_time. - `POST /{project_id}/annotations/query-targets`: Accepts now two additional sorting options: annotated_on, last_annotation_link_edit. The first one sorts by the date the matched annotations were added to the target. The second option sorts by when this link was edited last. - GET|POST `/{project_id}/skeletons/completeness`: Obtain compleness information on a list of skeletons. - `POST /{project_id}/skeletons/{skeleton_id}/find-labels`: The new optional bolean `only_leaves` parameter (default false) can be used to return only tagged leaf nodes (including root). Modifications ------------- - All APIs: errors during a request are now indicated with a more useful HTTP status code than 200: errors related to the request, input data and the client will result in status 400, permission errors in status 403, unavailable resources in status 404 and internal server errors in status 500. - `POST|GET /{project_id}/node/list`: Offers a new optional parameter "ordering", which can be used to order the result set of nodes. The values cable-asc and cable-desc are allowed. By default no ordering is applied. - `POST|GET /{project_id}/volumes/`: Information on area, volume and watertightness is now returned for each volume as well as information on whether these details have been computed (meta_computed). This meta data can be computed for each volume using the `{project_id}/volumes/{volume_id}/update-meta-info` API. - `GET /{project_id}/volumes/{volum_id}/update-meta-info`: Try to compute area, volume and watertightness for a volume. Sets `meta_computed` to true. If this operation fails, all meta data fields are set to NULL/None. - `POST /{project_id}/annotations/query-targets`: Accepts now an optional boolean "name_exact" parameter, which is set to false by default. If set to true, the passed in name has to match exactly. This is faster than using a regular expression like '/^name$' for exact matches. - `POST /{project_id}/skeletons/import`: The new parameters `source_id` and `source_url` allow to associate a source data reference with the imported skeleton. The new list parameter "annotations" can have annotation names, which are added to the import skeleton. By default only the annotation "Import" is set. - `POST /{project_id}/skeleton/join`: The new parameter `lose_sampler_handling` controls how to deal with samplers defined for the merged in skeleton. Possible values are 'delete-sampler' and 'keep-sampler', the latter being the default. If samplers should be kept, it is required that the sampler domains are defined on parts of the skeleton that don't need local rerooting. Otherwise an error is raised. Deprecations ------------ None. Removals -------- None. -----BEGIN PGP SIGNATURE----- iQJIBAABCAAyFiEEcCprn1Qmc4Ga52d87CoFhulcmScFAl5IwREUHHRvbUB2b29k b28tYXJ0cy5uZXQACgkQ7CoFhulcmSf0axAAhujVxVA/x4C425fS05c753U9P73H /xjoNRBUl0UGCjJUi/qMihVX95dzts1fxGmBtavTXyqRYVzS6VCaZ5zniaQIlyi0 dZG6kOXsNBF5cXmknkgHYShIAE4UbUBsG8FzkGPZuGjv/rp+FTDj3bgURSlofaNn K4rW7cnc4jo0j1KDZsteqK9wfCtZRJtvTIIvrFTtF5q6a4dBGjCzluK5xgo8uX66 HNICY32F6awrxOfRH2S3g8PVhbAkqCEVYw6VTiZORHt0vWJBIhlZ92s5HcUwlTCd 2nxsdKMKQEenkb1QwdQ6WWN9uZoJcxBFuvY1o6rNGPXmrodSWRmwAGBwONVHxpFP rq8EfUA5BoiV68wY0PUw90s1ZQp83n+LoisYoS+j3Av85dGNlqmRx00sxq3y25eq O2r+Apaacog1HAKwi1i/rwRGsClmtdUJv6Af8bSW5Nxw+s93oKWqkjv6BkxLmBjZ 3jbnLdAbyAPN6zvLLrvVyd+8ObPDQY4Om5UEheU4weCWCT5oiqQMOURo7N1YJ5LT Z8SyaxyorUuF7i74I96fa7+mHsjkVzUZq4yYdgxZjmZxC54E/08Ea00f4GPzlUSU MqYGHgcFSnEQuw4RDWFoghFhqHqkBtEEw46G0EU6MeqTg0qhhoxgTlpB/MOFqSXk hcbm/xYR2b70b/k= =laD8 -----END PGP SIGNATURE----- | 16 February 2020, 04:12:01 UTC |
| refs/tags/2019.06.20 | 2019.06.20 | abe05d2 | 2019.06.20 ========== Contributors: Chris Barnes, Albert Cardona, Andrew Champion, Stephan Gerhard, Pat Gunn, William Patton, Tom Kazimiers Notes ----- - A virtualenv update is required. - All \*.pyc files in the folders `django/applications/catmaid/migrations/`, `django/applications/performancetests/migrations/` and `django/applications/pgcompat/migrations/` need to be deleted. - Python 3.7 is now supported. - Heads-up: The next CATMAID version will require Postgres 11, PostGIS 2.5 and Python 3.6 or 3.7. - Should migration 0057 fail due a permission error, the Postgres extension "pg_trgm" has to be installed manually into the CATMAID database using a Postgres superuser: `sudo -u postgres psql -d <catmaid-db> -c 'CREATE EXTENSION pg_trgm;'` - CATMAID's version information changes back to a plain `git describe` format. This results overall in a simpler setup and makes live easier for some third-party front-ends, because the commit counter is included again. The version display is now the same `git describe` format for both regular setups and Docker containers. - Tile loading is clamped to (0,0) again, i.e. there are no negative tile coordinates anymore by default. If you need them, set the respective stack's `metadata` field to `{"clamp": false}`. - To write to CATMAID through its API using an API token, users need to have now dedicated "API write" permission, called "Can annotate project using API token" in the admin UI. To restore the previous behavior (regular annotate permission allows API write access) the settings.py variable `REQUIRE_EXTRA_TOKEN_PERMISSIONS` can be set to `False`. This is done as a safety measure to prevent accidental changes through automation. - If R based NBLAST is used, make sure to execute to update all dependencies: `manage.py catmaid_setup_nblast_environment`. - The main documentation on catmaid.org has now a place for widget specific documentation as well. Only a few widgets have been updated yet, but more will follow. Features and enhancements ------------------------- Tracing tool: - Add a new Tracing Tool icon button to compute the distance between two nodes on a skeleton. Respects virtual nodes. - The globally nearest node can now be selected and brought into view using Alt + G, as opposed to selecting the nearest node in the current section using the G key without modifier. - Using the H shortcut now without an active skeleton, the most recently edited node of the current user (Alt: anyone) in the last active skeleton will be selected. Using Shift will look in all skeletons. - Using Shift + Alt + Click with a connector selected, will will now create a presynaptic node. This is consistent with the already existing Shift + Alt + Click behavior with a treenode selected, which creates a presynaptic connector. Graph widget: - GraphML files can now be imported, positions and colors are respected. This is useful if layouting is done in e.g. Gephi and coloring should be done in CATMAID. The help page explains a possible workflow for this. - The button "Group equally colored" in the "Main" tab will group all skeletons with the same color into a single group. The user is asked for group names for each color. 3D viewer: - A new synapse coloring mode has been added: polyadicity. The number of partner nodes for each connector is color coded (for synaptic connectors, this is the number of postsynapses). The colors and ranges can be configured through the "Polyadicity colors" button in the "Shading parameters" tab. This is basically a configurable version of an absolute "N with partner" coloring. - Branches with leaf nodes tagged "not a branch" can now be collapsed using the 'Collapse "not a branch"' checkbox in the Skeleton Filters tab. - The visibility of radius information can now be controlled using the "Show radius" checkbox in the "Views settings" tab. - History animations can now be exported in full length without requiring to guess the number of frames for the export. The animation export dialog will show an additional checkbox ("Complete history") if a history animation should be exported. If complete history is enabled, CATMAID will export the complete history of the exported skeletons. - Animations can now be exported as stream directly to a file, which allows for much larger exports (32GB maximum at the moment). - Fractional rotations are now allowed in the animation export. - The default time per rotation in the animation export is set to 15 seconds now, slowing down the default by a factor of 3, which makes it easier to look at. - Stack Z slices can now be animated. Configurable are the change frequency and the change step in terms of sections. This is available for animation exports as well. - Stack Z slices can now be thresholded to replace a background color with another color. If enabled and the sum of all channels is in a configurable range [a,b] it will be replaced with another color. - The rotation time for animations can now specified in seconds rather than angular distance. - The background color is now fully adjustable through the "backgorund" button in the "View settings" tab. - Basic support for Virtual Reality is now available on Windows platforms using a Mixed Reality / SteamVR.3D setup and Firefox >= v65. To enable, check the VR checkbox in the "View" tab and click the "Enter" button right next to it. Skeleton history widget: - A basic view of the change of a set of skeleton IDs over time based on all nodes that are part of a given skeleton ID or that have been in the past. - Skeleton history can also be used with past skeleton IDs to see into what skeleton they changed (if any). - All past and present treenodes with a passed in skeleton ID are tracked through the complete history and their path of skeleton ID changes is recorded along with the number of treenodes following a given skeleton path. - The widget shows a graph from origin skeletons to the final skeleton IDs in every available path, summing the treenode counts for each contributing path. - Existing skeletons are colored in yellow, past skeletons are colored in cyan. Selected skeletons are colored green. - Ctrl+Click on skeleton will select it and go to the closest location in it. Shift+Click allows selecting multiple skeletons. All selected skeletons are available through the Skeleton Source interface. Node and skeleton filters: - Filter rules support now an "invert" option during creation, which allows to create filters that include everything but whatever is matched by a particular filter strategy. This can be useful e.g. during neuron review to only look at segments that have been created by people other than oneself or connectivity everywhere excluding a particular compartment. Measurement table: - Node filters are now supported. Like in other widgets, the respective panel can be opened through the funnel icon in the widget title bar. Measurements are displayed for all independent fragments of a skeleton after a set of node filter rules has been applied. - With the help of the "Sum fragments" toggle all fragments that result from a node filter application can be aggregated into one row by summing individual values. Remote CATMAID instances - Some tools in CATMAID gained support to communicate with other CATMAID instances, e.g. the Landmark Widget (see below). To enable this functionality, remote CATMAID instances can now be added to the user settings. - The Settings Widget contains now a section labeled "Other CATMAID instances". It allows to manage a list of other CATMAID servers based on their URL, an API key and optional HTTP authentication. This information is stored under an alias. Landmarks: - Clicking on the name of a landmark group in the Landmarks tab will now open the group member edit dialog that was previously accessible by clicking any landmark name. Clicking a landmark name will now show a new dialog, which allows to specify of which landmark groups the clicked landmark is a member of. - The color of each active display transformation can be established separately in the respective table row. Color changes are now also visible in the 3D Viewer. - It is now possible to load skeletons and landmarks from other CATMAID instances. Point matches are done on the basis of matching landmark names. To enable the UI for this, check the "Source other projects" checkbox in the Display tab. - With the "other projects" UI enabled and a remote CATMAID instance configured in the Setting Widget (see above), it is now possible to select a remote CATMAID instance from the "Source remote" dropdown menu. Alternatively, the local instance can be selected if another project from the same instance should be used. - Next the source project in the selected instance needs to be specified. This list is updated when a different remote instance is selected. - Skeletons from a remote instance are collected through annotations. The respective annotation has to be entered in the "Source skeleton annotation". With the help of the "Preview" button it is possible to load the matching skeletons from their remote CATMAID to inspect if the correct ones are selected. - As a last step for the remote data configuration, the source landmark group has to be defined. This list is updated if the source project changes. Landmarks from this group are mapped to the selected target group. The matching is done by name, i.e. no landmarks can have the same names in a group. - Adding such a transformation adds it to the list at the bottom of the widget, just like with regular transformations and they can be used in the same way. The can be shown in 3D Viewers, superimposed on the Tracing Layer and used in NBLAST queries from the Neuron Similarity Widget (see below). - The new checkbox 'Multiple mappings' displays additional user interface elements to add multiple source and target landmark group mappings for a single display transformation. Point matches are created independently for each pair and only merged for finding the final transformation. - Using a transformation is now optional (but enabled by default). To disable landmark transformations, uncheck the "Apply transformation" checkbox. This allows e.g. to display skeletons from remote CATMAID instances without modification. Neuron Similarity: - The computation of the default "mean" normalized similarity scores is now considerably faster. - The new "Top N" option allows to store only the Top N best matches in the result set. For "mean" normalization, it will also only compute the mean score for the top N forward hits (mean is the average between forward and backward score). A value of zero disables this cutoff (default). This cutoff can be used speed up computation for very large sets of neurons or large point clouds. - The new "Reverse" option allows to rank similar objects by there reverse score. That means that the stored score for a particular object pair is target versus query rather than query versus target. NBLAST uses the query neuron as reference, and thereforoe the reverse option can make a difference as long as no "mean" scoring is used. - It is now possible to use display transformations defined in the Landmark Widget that reference another CATMAID server as their data source. They can be used both as source and target for NBLAST comparisons. This makes it essentially possible to compare skeletons from another CATMAID project, possibly on another CATMAID server, to local skeletons using NBLAST. - Similarity matrices can now include transformed skeletons in their set of similar objects. To do so, create a Display Transformation in the Landmark Widget that represents the wanted transformation and the select it from the "Sim. transformed skeletons" drop down in the Configurations tab of the Neuron Similarity Widget when creating a similarity matrix. - Similarity matrices can now be created with more control over which skeletons are looked at as similar. The drop down menu "Similarity mode" allows to select different groupings of the input skeletons (and transformed skeletons). It is for instance possible to group a neuron and its contralateral partner that has been transformed to the side of the first neuron as similar. A confirmation dialog presents the computed grouping before actually creating a similarity matrix. - Similarity matrices can now be imported from CSV files, optionally including the distance binning and dot binning as header row and column. As part of the import, the distance binning can be scaled to adjust for differences in datasets. This is available through the "Create from CSV file" button in the Configurations tab. - Similarity query results can now be used as skeleton source in other widgets, if the target type of the query are skeletons. System check widget: - A subset of important database statistics are now displayed if a user has the "can_administer" permission in a project. These statistics include e.g. cache hit ratio, temporary files, requested checkpoints and replication lag. For most of them a rule of thumb suggestion on how a value should behave is provided as well. Extension: CATMAID-autoproofreader: - This extension is written by Will Patton and has to be installed separately, because it requires additional setup steps for segmentation data handling. Details can be found here: https://github.com/pattonw/CATMAID-autoproofreader. - This tool suggests locations in a skeleton reconstructions where branches might be missing or wrongly connected. Users can step through these suggestions to fix potential problems. After reviewing a node it can be marked as reviewed for future reference. - In the CATMAID front-end the autoproofreader provides a widget that relies on a compute server to handle the computations involved with automatically proofreading a neuron reconstruction. Proofreading jobs are performed asyncronously and might take a few minutes to complete. Administration: - A grid based node query cache can now be used to speed up tracing data retrieval by precomputing intersection results. This can be useful for larger field of views in big data set. It supports multiple levels of detail per grid cell and can therefore provide a somewhat uniform sampling when limiting the number of displayed nodes. The sorting of this LOD configuration can be controlled so that e.g. only the top N largest skeletons will be shown per cell with growing LOD. The documentation has more details. This cache can be kept up updated using two extra worker processes that listen to database changes, implemented as management commands `catmaid_spatial_update_worker` and `catmaid_cache_update_worker`. - The database can now emit notifications on tracing data changes using the "catmaid.spatial-update" channel and when grid cache cells get marked dirty on the "catmaid.dirty-cacche" channel. These can be subscribed to using Postgres' LISTEN command. To enable emitting these events and let cache update workers work, set `SPATIAL_UPDATE_NOTIFICATIONS = True` in `settings.py`. This is disabled by default, because sending events for spatial cache updates can add slightly more time to spatial queries, which will mainly be relevant for importing and merging large skeleotons. - Projects can now be deleted along with the data that reference them (e.g. treenodes, ontologies, volumes). To do so select the projects to delete in the admin project list and select "Delete selected" from action drop down. - Users can now be set to an inactive state after a specified amount of time. This time is configured for a user group and it applies to users if they are members of such a group. A message can optionally be displayed as well as users to contact that could potentially help. This is configurable as "Group inactivity period" in the admin view. Users to contact for support, can be either configured there or from individual user views. CLI Exporter: - If both required annotations and exclusion annotations are provided, the importer will now only exclude a skeleton if it is not also annotated with a sub-annotation of the required annotations set. This behavior can be disabled and exclusion can be enforced when a skeleton is annotated with the exclusion annotation or one of its sub-annotations. To do so, use the new "--exclusion-is-final" switch. - Volumes can now be exported by using the `--volumes` switch. By default all volumes of the exported project will be included. This can be further constrained by using `--volume-annotation <annotation-name>` arguments. - The way she exported objects are specified through the command line interface changed. Instead of writing e.g. `--notreenodes` to not import treenodes from a source, `--treenodes false` has to be used now. This is the case for treenodes, connectors, tags and annotations. The defaults (when the argument is not provided) stay the same. To explicitly disable the export of a type `false`, `no`, `f`, `n` and `0` can be provided as argument, e.g. `-treenodes false` or `--users n`. For a positive parameter use `true`, `yes`, `t`, and `1`. CLI Importer: - Precompute materializations (edges, connectors) explicitly only for imported data, which improves performance in typical scenarios (import is small compared to existing data). If the old behavior of recomputing everything in the target project should be used in cases where a full data base is imported, the --update-project-materializations switch can be used. - The way she imported objects are specified through the command line interface changed. Instead of writing e.g. `--notreenodes` to not import treenodes from a source, `--treenodes false` has to be used now. This is the case for treenodes, connectors, tags and annotations. The defaults (when the argument is not provided) stay the same. To explicitly disable the import of a type `false`, `no`, `f`, `n` and `0` can be provided as argument, e.g. `-treenodes false` or `--users n`. For a positive parameter use `true`, `yes`, `t`, and `1`. - Imported usernames can now be mapped to existing usernames and mapped selectively by using one or more parameters of the form --username-mapping="import-username=target-username". The example would map all references to the user import-username in the imported data to the existing user target-username. The mapping is performed even with --map-users off. - It is now possible to import volumes from CATMAID export files and other projects.. Miscellaneous: - Tracing layer: a minimum skeleton length can now be specified in the layer options, causing the Tracing Layer to show only nodes of skeletons of at least this cable length (nm). - Tracing layer: a minimum number of nodes can now be configured to only show skeletons of at certain minimum size (just like the existing minimum cable length constraint). This is configurable through the layer configuration, accessible by clicking the blue/white box in the lower left corner of stack viewers. - Settings widget: visibility group conditions can now be inverted. - Confirming a radius selection (Shift + Y) can now also be done using the Enter key. - Neuron name searches and annotations should be much faster on larger instances. - Basic support for touch screens (e.g. phones and tablets) is now implemented. - CATMAID can now export files (e.g. CSVs, videos, etc.) of much larger size than before, if "Save exported files in streaming mode" is enabled in the Settings Widget. To make this work, the browser settings (chrome://settings) "Ask where to save each file before downloading" has to be enabled. - Context aware help: by clicking the new question mark icon in the upper right corner, a context aware help dialog can be displayed on top of all other CATMAID tools. It provides some general guidance for the intended workflow with individual tools. This can be enable to be displayed by default as part of the Settings Widget. The display of this can also be enabled in a link to a view by appending `&help=true`. This will be added automatically if a help dialog is open during URL creation. - Connectivity widget: the new "List links' button will open a Connector List with all links of the selected neurons. - Selection table: the new checkbox "Link visibility" allows to change the behavior of the visibility checkboxes. So far the pre/post/text/meta select-all controls were only affecting the respective visibility options of visible/selected skeletons (default). With unlinked visibility pre/post/text/meta can also be controlled for all neurons, regardless of their visibility. This allows e.g. to only show synapses, but no skeletons. - General search widget: a more flexible table is now used for display, which allows sorting, filtering and pagination. - Neuron dendrogram: select currently active node by default when loading the dendrogram for the active skeleton. - The right end of the status bar contains now a button to toggle the visibility of the top toolbars. - Updating the copy of client side annotations will only request new data if there are actually new annotations. This makes loading of e.g. the Neuron Search widget faster. - Boss databases can now be used as tile source type so that image data is loaded from them. More details: https://docs.theboss.io/docs/image. - Docker: HTTP basic authentication can be configured by using the environment variables HTTP_AUTH_ENABLED, HTTP_AUTH_USER and HTTP_AUTH_PASS in the web container of the `docker-compose.yml` file (an example is given). - Performance: selecting the closest node in a skeleton should now be faster. Bug fixes --------- - A race condition has been fixed that could in rare cases lead to inconsistent skeleton IDs in a skeleton that is merge into different skeletons by different requests. - Landmark transformations: fix Moving Least Square transformations for skeleton fragments outside of source group bounding box. - The Connectivity Graph Plot draws now individual bars in each sub-plot side-by-side and uses the same neuron names as other widgets (from CATMAID's neuron name service). - Information based on historic information like the history animation in the 3D Viewer and the Neuron History widget includes merge information now correctly. Before, merge nodes were represented twice in a time slice that included the merge. - The default connector type is now properly persisted as a setting. - Neuron search: no duplicate entries are shown anymore, which could result e.g. when sub-annotations where allowed. - Neuron similarity: when showing result skeletons in 3D, skeletons are now appended to the Selection Table of a 3D Viewer, rather than the 3D Viewer directly. - Connectivity widget: the auto-connectivity CSV will now use formatted neuron names as column and row headers. - Connectivity widget: the 'Export CSV' button will now respect name and annotation filters. - Graph widget: ungrouping of one-element groups is now allowed. - Graph widget: merging of grouped skeletons is now handled properly. - 3D viewer: the depth test for connector partner spheres is now performed correctly and spheres should be rendered in the correct Z order. - 3D viewer: mouse controls now work correctly in fullscreen mode. - 3D viewer: the suggested width and height of the animation export are now by default a factor of two. This is required by the WebM encoder. Off values are reduce by one. - 3D viewer: spatial select works now also without the active node highlighted. - 3D viewer: no error is shown any more when attempting to move while in radius edit mode. - 3D viewer: landmark transformed skeletons show now also radius spheres. - Connector table: the section and tag columns are now part of the CSV export. - Tracing tool: unneeded node updates are removed from initial tracing layer loading. - Selection table: don't try to load missing skeletons from JSON file. - Settings widget: default values for tracing layer skeleton limits can now be configured under Tracing Overlay > Tracing layer skeleton filters. - The numpad delete key is now recognized as regular delete (if numlock is off). - SWC neuron import: providing a neuron ID for an import works again and will now also set an optionally provided neuron name. Additionally, it is now required that a user importing skeleton data for an existing neuron ID has the rights to edit the skeleton instance as well as all its treenodes. - Volume widget: volumes/meshes with annotation can now be removed properly. - Volume widget: editing a volume by double clicking its table entry works again. - Neuron dendrogram: correctly reload skeleton if it changes as a result of a split or merge. If a dendrogram node is selected, the respective skeleton will be reloaded after a split, even if its ID changed. - The Notification Table can be opened again without errors. - Exporter: connector links are now exported properly if the parameter --original-placeholder-context is used. - Docker: the docker-compose setup now uses Postgis 2.5 internally and therefore allows upgrades from Postgres versions < 10 with Postgis 2.4. - Docker: stale Postgres PID files will now be removed during a database upgrade in a docker-compose setup. PID files without actually running database processes prevented some updates before. - Initial setup: create_configuration.py now also prints the media files directory as part of the webserver example configuration. This is the folder where e.g. some exported files are made available. API changes ----------- Additions --------- - `GET /{project_id}/nodes/nearest`: Replaces `POST /{project_id}/node/nearest`. The parameters are the same, but the API allows now to look globally for the nearest node in the project, if no skeleton ID or neuron ID is provided. - `GET /{project_id}/nodes/most-recent`: Replaces `POST /{project_id}/node/nearest`. A skeleton_id parameter can still be provided, but now also a user_id parameter is available to further constrain. Modifications ------------- - `POST|GET /{project_id}/node/list`: Offers a new optional parameter "min_skeleton_length", which can be used to constrain the returned neurons to only those of at least this cable length. - `POST|GET /{project_id}/pointclouds/`: Offers a new optional parameter "order_by", which accepts the strings 'id' and 'name' to define in what order the list of pointclouds should be retuned (default: id). - `POST /{project_id}/landmarks/{landmark_id}/`: Offers a new optional parameter "group_ids", an array of integers, which allows to set the landmark group memberships of a specific landmark. The new boolean parameter "append_memberships" allows to only append new group IDs as memberships, without removing any. Otherwise the whole set of memberships is replaced. - `POST /{project_id}/skeletons/import`: The new parameter `skeleton_id` makes it possible to request a particular skeleton ID during import, just like it is done for neurons using `neuron_id`. If a skeleton or neuron with this ID exists already, a new object is created and the existing one is not touched. If an error should be raised instead, set the `auto_id` parameter to `false`. If instead the passed in IDs should replace existing data, the `force` parameter can be set to `true`. Both options apply to both neurons and skeletons. - `POST /{project_id}/skeletons/connectivity/csv`: The new optional parameter `names` makes it possible to pass in a mapping of skeleton IDs to names used in the CSV export as column and row headers. If this parameter is not provided, the plain skeleton IDs will be used as it was done before. If it is provided, it has to be a list of two-element lists, each of the form [<skeleton-id>, <name>], which provides the mapping. - `POST /{project_id}/skeletons/connectivity`: The `source_skeleton_ids` parameter can now also be specified in regular form format (multiple arguments with the exact same name), rather than only the square braces style. Deprecations ------------ None. Removals -------- - `POST /{project_id}/node/nearest`: Replaced with `GET /{project_id}/nodes/nearest` (note the plural of nodes). - `POST /{project_id}/node/most-recent`: Replaced with `GET /{project_id}/nodes/most-recent`. -----BEGIN PGP SIGNATURE----- iQJIBAABCAAyFiEEcCprn1Qmc4Ga52d87CoFhulcmScFAl0MUNsUHHRvbUB2b29k b28tYXJ0cy5uZXQACgkQ7CoFhulcmScZ2g//RormJ5atRvkqq+Eq5KyLXgpPxI2B GkSnPGSBBYn2/dW6rjQoSbKvuUZzypl+998cV/bSUqbUHyU5SOEmoLquLzEIwG/b lQikHfaFFIktbdJYY2t/m8OpUDLYOGQO2sISgMx8UAdGXQReNl/BRsN9cNjdP+Yg VpF5gt/FwG8klx4qiidwM1/mz5ZtNftqM94J+B//2494Yx5SfAeqhvejDnEDISVa zWQXwkK96rbWfv4WvAqXu3ec7Ob7lX+ZrO0uJo8QRtG3q9oBnD4KZYOTH60slQdo h3ikQa/MEcvRmtA54DmbfKFt4fSkWB9qMWPxOCJuwOaUphLMRycAtfV5R+42IKyH T4ITBJcR8KA8cMpgMerPxJbQ2Z9yC2aY8WKItZkCkFbexKp4b3dh1Qu0okyhQ3na H3BBpVEo0+Mg5v+DIsX9yR8LzEA0GV/iKzbuPR5aGO2kCD/filf0CF5CP5kHBDFb +PvU01wR4uualyxeC8GWIkLnuJE555z2rT2TEQtIv4m5M18cw8FIblT/c7A1oXeK EiTOcrH5w2WOo2vrpbYdq3yozJqt9RvHQAgX3Mv46eYMB8dBRTKe9YHVvqTi0y3h sC8aKzhQlN5xookqRpUbxWCY4WBrKfPwKxiwAtBLg/2AD3F4KFv4i9CBhU6sQbVV AY6N09U0HYcKff8= =95w9 -----END PGP SIGNATURE----- | 21 June 2019, 03:36:59 UTC |
| refs/tags/2018.11.09 | 2018.11.09 | 0e2b5fe | 2018.11.09 ========== Contributors: Andrew Champion, Chris Barnes, Tom Kazimiers, William Patton, Eric Trautman Notes ----- - Python 3 is now required for the back-end. We recommend the use of Python 3.6. - CATMAID's version information is now presented in a different form. It follows the pattern `<base-version>[-dev]-<commit>`. The `<base-version>` is baked into the source code on a release. The `-dev` part will only be present if CATMAID's `dev` branch is used for deployment. It won't be present for `master` branch based setups. The `<commit>` part is the 10 digit version of the Git commit ID. This version representation is now also consistent with what is display in Docker images. In the rare event that no commit information can be found, `<commit>` will fallback to "unknown". This version will now also logged during start-up of the back-end. Features and enhancements ------------------------- Connectivity matrix: - The new checkbox labeled "Fractions" in the "Main" tab makes it now possible to display connector fraction instead of an absolute link number in each cell. The number of connections from one source row to a target column is divided by the number of total posynaptic connections that are made to the target skeleton (column). This makes columns better comparable to each other. - The auto-connectivity matrix of a large set of skeletons can now be exported as CSV without displaying it using the "Auto-connectivity CSV" button. This makes it possible to export larger connectivity matrices in a usable format. - The aggregation method for the connectivity count in groups can now be selected. Available are: sum (default), min, max and average. 3D viewer: - Treenodes that are linked to connector nodes can now be scaled independently from other node handles using the "Link node scaling" option. - Volume picking is now optional and disabled by default, i.e Shift + Click will go through volumes. To enable volume surface location selection, the "Pickable" checkbox needs to be checked. - If Reconstruction Sampler domain shading or interval shading is used, a list of valid domains and intervals can now be specified in the "Shadings parameter" tab. - The X/Y/Z rainbow coloring modes are now also available normalized to each individual skeleton. - Add custom connector coloring. The pre and post colors can be adjusted in the "Shading parameters" tab. - The X/Y/Z/ axes can now be displayed in the lower right corner using the "Axes" checkbox in the "View settings" tab. Reconstruction sampler: - Improve performance of interval length computation - Sampled skeletons can now be split after the users confirm this is their intention. The split-off part of the skeleton will not contain any sampler information anymore. Intervals on the split-off part are removed, split-point crossing intervals are shortened and domain end points will be removed and recreated as needed. - Sampled skeletons can now be merged into. All samplers that reference the merged-in fragment are deleted. If the merged fragment is merged outside of a domain, nothing special is happening---it is a regular merge. If the merge treenode is in a sampler domain, there are currently three options, "Branch", "Domain end" and "New domain": 1. Branch: add the new fragment to the skeleton without changing domain end nodes or intervals. This is only allowed if the merge target is not the start or end of an interval. 2. Domain end: add a new domain end node right where the merged in fragment starts. This keeps the new fragment isolated from the sampled domain. 3. New domain: a new domain is created for the merged in fragment. This also adds the domain end node from (2). - Domain completion is now shown in percent along with interval coverage of the domain in "Interval" step. - Merge decisions can now be limited when the 'merge' or 'merge-or-create' leaf handling mode is selected. This means a percentage can be specified which defined below which ratio of extra cable versus interval length the extra cable should be merged into the previous interval (if possible) rather than a new interval is created. - Ignored lead segments can now be inspected in more detail using the "Uncovered domain parts" button the "Interval" step. This will open a dialog window with a histogram on all ignored leaf segments in the current domain. Clicking on individual bins will open a treenode table containing the respective start nodes of the ignored leaf segments. From this dialog, it is also possible to list all downstream/upstream partners linked to nodes in ignored segments of a domain. - For samplers using the 'ignore' leaf handing mode, it is now possible to update this to 'short-interval' mode including the generation of missing intervals for existing domains. A visual confirmation dialog is shown. To use this, press the "Set short-interval leaf mode" button in the Domain tab. - The Synapse tab now also shows all leaf nodes of an interval. This makes it easier to find the places where an interval needs to be continued. Tracing layer: - Tracign layer: cycle open end in reverse using Shift + Alt + R. - Alt + Click now opens consistently the link type context menu, regardless of whether a treenode or connector node is currently selected. - The layer options now allow to select a user who's tracing data won't be fetched from the server. The main motivation is to hide data imported by a dedicated import user by default and not even fetch it from the server. - Similar to image data mirrors, it is now possible to configure read-only tracing data mirror servers from which the tracing data will load all data except for the active node, which will be read from the main server. This is particularly useful if connecting to the main server from a remote location. To make this work reliably, it is expected that physical replication is setup on the database level that mirrors the main server constantly. A separate CATMAID instance needs to be setup on the mirror server as well. To configure this, the "Read-only CATMAID mirrors" option in the settings widget can be used together with the "Read-only mirror index". Neuron similarity: - The new Neuron Similarity Widget makes it possible to compare neurons to each other, to neurons transformed based on landmarks as well as to arbitrary point clouds. Point clouds can for instance be created from light microscopy data. It creates a similarity ranking based on NBLAST. To open the widget, use Ctrl + Space or the Open Widget button and then search for "Neuron similarity". - To compare two different objects, NBLAST will compare a query object pairwise with potential target objects. It iterates over each point of the query object, find the closest point in a target object and computes a score based on the distance of these points and their orientation to each other. - This scoring is done based on a scoring matrix, which needs to be created before any comparisons can be made. Scoring matrices are typically reused and don't need to be recomputed every time. The "Configurations" tab allows to create new similarity matrices and lists existing ones. For a new scoring matrix, probabilities for distance and orientation are computed for both a set of of similar neurons and a representative sample of random neurons. Both are combined into a single matrix in which a value of zero makes a particular a pair of points equally likely to be random or to be a match. Values above zero make a match more likely. Computed similarity matrices can be visualized by clicking the "View" link in the Scoring column of the respective similarity configuration. - With a similarity matrix computed, similarity queries ca be performed from the "Neuron similarity" tab. In its most basic form, this compares neurons to other neurons. It is also possible to select transformed neurons and point clouds as query type or target type in a search. This however requires additional setup (see below). Query and target skeletons can be selected by selecting a skeleton source for each. A similarity matrix has to be selected as well, but all other options have reasonable defaults. A click on "Compute similarity" queues a new similarity request, which is computed asynchronously. Once the task is complete its table entry will switch its status to "complete". - Once completed, the similarity query results can be viewed by clicking on "View" in the "Scoring" column. This will open a new result window (or dialog, if selected in the "View" option), which shows the similarity ranking. - To query with or against transformed skeletons, a landamark based "display transformation" has to be created. To do so, open the Landmark Widget, and create a transformation in its "Display" tab. Transformations created this way are selectable from the Similarity Widget, if "transformed skeletons" is selected for either query or target. Depending on available landmark groups, this could be for instance a skeleton transformation to its contralateral location. - The Point cloud tab allows to import individual point clouds, along with an optional transformation and representative images. It also provides a list of all point clouds that are visible to the current user. A group visibility option during import allows to restrict visibility of imported point clouds to selected groups (which need to be added from the admin interface). - The "Point cloud import" tab allows to import many point clouds at the same time, optionally transformed and with linked representative images. Volumes: - The general widget controls are now distributed across tabs. - Annotations can now be used on volumes too. The "Annotate" button in the Volume Manager can be used to annotate all selected volumes. - The "Add from file" button in the Volume Manager can now be used to import volumes from STL files. - The "Skeleton innervations" tab allows to search for volumes that intersect with a set of query skeletons. A volume annotation can be specified to look only at volumes having this annotation. Optionally, exact result computation can be disabled to only compute skeleton/bounding-box intersections. This is slightly faster, but leads to false positives. Docker: - More CATMAID configuration options are now accessible through Docker environment cariables: CM_DEBUG, CM_FORCE_CONFIG_UPDATE, CM_WRITABLE_PATH, CM_NODE_LIMIT, CM_NODE_PROVIDERS, CM_SUBDIRECTORY, CM_CSRF_TRUSTED_ORIGINS. - The Git commit from which a Docker image was built is now preserved and included in the CATMAID's version information. CLI importer: - If no user information except for IDs is present in the imported data, the importer will by default ask for a username and create new inactive users for those IDs (and update the referenced IDs). Alternatively, the --map-user-ids parameter can be specified, which will make the importer map referenced IDs to existing users. If an existing user with the respective ID is not available, the user is asked for a username and a new user will be created. - With the help of a few additional progress bars, import progress can be better monitored. - Database statistics are now automatically recomputed after an import, i.e. ANALYZE is run. Miscellaneous: - Each Tracing Layer is now listed as a skeleton source. All skeletons visible in their fields of view are made available to other widgets that way. - Tracing tool: add icon button to toggle a node coloring mode in which each node is colored according to the length of their respective skeleton. The colors and cable length values when to use it can be set for three colors in the Settings Widget in the "Skeleton length coloring" section. - The SWC exporter can now optionally mark a node as soma if it either is tagged as "soma", if it has a radius larger than a defined value or if it is the root node. All three conditions can be selected, and they will be applied in the order they are listed above. If selected, a soma tagged node will always take precedence. - There is small copy-to-clipboard button left to the "URL to the view" link in the upper right corner of the user interface. - The Ctrl modifier can now be used with - and + to animate zooming. - New widget: stack info, which displays properties for stacks related to the active project. - The node cache update management command `catmaid_update_cache_tables` can now update all caches configured in the NODE_PROVIDERS settings variable automatically when the `--from-config` option is provided. - Admin: a projects/export JSON export of the visible project/stack structure can now be used directly in the Project/stack Importer by selection "JSON representation" as source and pasting the data into the text field. - Neuron search: regular expressions are now optional for the neuron name. Unless the search string starts with '/', no regular expressions are used, but a regular case insensitive text search. - Two new connector types are available: "tight junction" and "desmosome". Both can be created through the Alt + Click menu, are reciprocal and two links at one connector are allowed for each type. - Connectivity widget: all available link types can no be selected to be displayed. Both the gapjunction and attachment checkboxes have been removed in favor of a more generic list select element. - Tracing layer: the displayed tracing data can now be constrained to show only the N most recently edited skeletons. This settings adds to the skeletons selected by the N largest skeletons filter. - WebGL layers are now preferred by default. - Project statistics: a top ten of the largest neurons is now displayed. - Admin: a user import view is now available to import users from other CATMAID instances. It requires superuser permissions on the remote instance. - DB integrity check management command: volumes are now checked to make sure all faces are triangles. The --tracing [true|false] and --volumes [true|false] command line parameters now allow to explicitly test only some parts of the database. By default all is tested. Bug fixes --------- - 3D viewer: loading a single node skeleton with smoothing enabled no longer causes an error. - 3D viewer: nodes taged with 'uncertain' can be loaded again. - 3D viewer: various rendering bugs for Reconstruction Sampler domains and intervals have been fixed. - 3D viewer: stored node scaling settings are now properly restored. - 3D viewer: TODO tag coloring doesn't override custom label colors anymore. - 3D viewer: all synaptic site spheres are created and colored again. - 3D viewer: camera won't flip anymore if it is upside down during animations. - Tracing overlay: the border of the tracing window is now properly rendered. - Tracing overlay: child node edition times are now correctly updated if the parent is deleted, which fixes occasional state matching errors. - Tracing overlay: Shift + Click now works also with attachment connectors, should they be selected as default connector type in the settings. - Reconstruction sampler: deleting samplers while other samplers on the same neuron refer to the same created boundary nodes no longer causes an error. - Reconstruction sampler: cable length columns are now sorted numercially. - Reconstruction sampler: all settings are now correctly reset when a sampler is selected or "New session" is pressed. - Reconstruction sampler: a few corner cases for binary interval coloring have been fixed. Colors should now alternate in most cases. - Connectivity matrix: synapse count based ordering works again. - Connectivity widget: annotations on neurons (used for filtering) are now properly updated when they are changed in another part of CATMAID. - Graph widget: edge color updates now trigger a redraw operation again. - CLI importer: the ID sequence for the auth_user table is now properly reset after an import. - CLI importer: missing treenode-connector links are now imported between connectors and placeholer nodes. - CLI impoerter: the ID of reused objects is now proplery updated in imported data when --preserve-ids is used. - CLI importer: skeleton summaries and edge tables aew correctly created again. - CLI importer: unmapped imported users are now correctly saved. - The error dialog prints now linen breaks and spaces correctly again, which improves its formatting. API changes ----------- Additions --------- - `POST /{project_id}/skeletons/cable-length`: The POST version of the already existing GET endpoint. It allows passing in more skeleton IDs for which to get the cable length. - `POST /{project_id}/skeletons/connectivity-counts`: Allows to get the number connector links per relation type for each passed in skeleton. Also accepts GET parameters. - `POST /{project_id}/skeletons/connectivity_matrix/csv`: Return a CSV file containing the connectivity matrix for the passed in `rows` and `columns`. - `POST /{project_id}/skeletons/sampler-count`: Return the number of samplers linked to each skeleton in the passed in `skeleton_ids` list. - `GET /{project_id}/skeletons/{skeleton_id}/sampler-count`: Return the number of samplers linked to this skeleton. - `GET /{project_id}/labels/detail`: Returns a list of of label objects, each with a name field and an ID field. - `POST /{project_id}/volumes/import`: Import volumes as STL files. - `GET /{project_id}/volumes/{volume_id}/export.{extension}`: Export a particular volume. Currentl only exports AS STL are supported. - `GET /{projec_id}/stats/cable-length`: Get the top N largest skeletons. N can be specified using the 'n_skeletons' parameter. - `POST /{project_id}/volumes/skeleton-innervations`: Get a list of all volume/skeleton combinations that intersect. Skeletons are provided with a 'skeleton_ids' parameter. This can be constrained by volume annotation, cable length and node count. - `POST /{project_id}/volumes/`: Previously only the GET method would be supported. With the introduction of an optional `volume_ids` parameter, POST can be used as well. This parameter can be used to constrain the returned set of volumes. Modifications ------------- - `POST /{project_id}/skeletons/node-label`: The new `label_names` parameter accepts a list of strings that an be used instead of or together with label IDs to get skeletons with nodes that have particular labels. - `GET /{project_id}/stacks/{stack_id}/info`: Now includes the `comment` field for each stack. - `GET /{project_id}/connectors/`: The partner data returned when the `with_partners` is set, includes now additionally the creator of the link and the creation and edition time (in epoch format). - `GET /user-list`: Accepts a new boolean parameter `with_passwords` to export encrypted passwords, which in turn can be imported into other CATMAID instances. This requires the requesting user to be a superuser. - `GET /{project_id}/skeleton/{skeleton_id}/swc`: A new optional parameter `soma_markers` can be supplied. It is a list of 'tag:soma', 'radius:<n>' and 'root'. These are conditions for when a node is marked as soma in the SWC export. The first matching condition in this order wins. - `GET /{project_id}/volumes/`: The return format changed. Instead of a list of volume objects an object with a 'columns' field and a 'data' field are returned. The data fields contains a list of lists, with each inner list being a volume. The entries are described by the 'columns' field. Along with the already returned fields, annotations are now retuned as well. - `GET /{project_id}/volumes/`: An optional `volume_ids` parameter can now be used and the POST method is supported as well (to transfer larger volume ID lists). This parameter can be used to constrain the returned set of volumes. - `POST /{project_id}/skeletons/connectivity`: A new optional option 'link_types' allows to specify which connectivity types should be returned. By default 'incoming' and 'outgoing' is returned. Additionally, the following options are allowed: gapjunction, abutting, attachment, close_object. The return field names have also been adapted to these parameters and match them. Instead of 'gapjunctions' and 'attachments', the fields are now named 'gapjunction' and 'attachment'. - `GET /{project_id}/annotations/`: Supports now an optional boolean parameter named `simple`, which returns only names and IDs and is therefore much faster. Deprecations ------------ None. Removals -------- None. -----BEGIN PGP SIGNATURE----- iQJIBAABCAAyFiEE0ZcfpSuTdC1Kl2UqCBqeIVvdIIMFAlvlLIUUHHRvbUB2b29k b28tYXJ0cy5uZXQACgkQCBqeIVvdIIPPNQ/7BagofWwOqFA8teOGn3JilYCPe6dA xWU3/0zR4c5uxpnzbQc2jruDQLan/S120kXiNg03MSFJXcKDGXA0K6uL+hmqyII+ NzDume85LR2IcxB+2GnXUEIH3hw4gYFV4BCK+98YV+xZkYEB71PSXcLMiKafZ6Lc xpfDf39dG9nQSrmtesv/ruzFK9XYjMWoJJUm0oDr4vaokV3ArxNukq8mNXUrQ6lS kQQFmM6L7zSyBy0Hq3Fp+t210i6zh9P8lV9y2gkYugVtjaymNOhYwJIwp51/yD55 JHMuiwtsmya0f5Uu3tH7bcI91HRZMpNRCJ26OeiAmMaUe7CNsBpSNBzi9MoTSNBV IjW+8Lt66md3QOf6lOY7/f7R1ATrVxe5jSAdLF584rn5mnXacxonhEJx6BUbQ/2H NAD3TmDctP4VSUhvhkMk797KUQMN8nv/YT0J615aJN0SaI+9p3CeFuZHrTyv3PaM m4U5N8TFH+XohdiZ0ldZZLqUWV41sUBy/rVg8jhzMgyrMHRrVvlMflKJSJP3uPy6 4XqnQYtsrGU1i6HalZpsmxPLCl6zS0FxPlSc76s4N9qpsXXcIoT3ErT0pZhFbNt6 +9aW4/mF4Fu+PEizzaCNKyvi9qwpADR82i8Zj+X+7U0GutbCRFZCsbuXPt4Hd359 PNLC8aYvMPaShQ0= =T0HG -----END PGP SIGNATURE----- | 09 November 2018, 06:43:17 UTC |
| refs/tags/2018.07.19 | 2018.07.19 | 16afda4 | 2018.07.19 ========== Contributors: Albert Cardona, Andrew Champion, Pat Gunn, Tom Kazimiers, Will Patton, Eric Trautman Notes ----- - Both the standalone Docker image and the Docker-compose setup can now be updated after a Postgres version change. This makes it possible again to use CATMAID versions after 2018.02.16 with Docker. The documentation has more information. - This is the last CATMAID version with support for Python 2.7. Starting from next version, only Python 3 will be supported. Features and enhancements ------------------------- Volume widget: - Add a "List connectors" link to each volume, to show all connectors in a volume bounding box. - The new "Min skeleton nodes" and "Min skeleton length" options allow to further constrain volume based skeleton selections ("List skeletons"). - The Connector List widget that is shown when clicking on "List connectors", now supports connector filtering. The volume of the link's row is now automatically set as filter in the new Connector List widget. This means connector links in this table are now shown only if they intersect exactly with the volume (and not only with the bounding box like before). - State saving is now supported. 3D Viewer: - The line width of skeletons can be adjusted again on platforms other than Linux. This Requires "Volumetric lines" in the "View settings" tab to be enabled (it is by default). Unchecking this option brings back the previous line rendering behavior. - The new "Focus skeleton" button in the "View" tab will look at the active skeleton's center of mass from the current camea location. - Volumes can now be smoothed by subdivision. The volume option panel available from the View Settings tab now contains a "Subdivide" checkbox. - A volume's bounding box can now be displayed using the "BB" checkbox that is available for visible volumes in the volume option panel. - New coloring option: X/Y/Z rainbow lookup table coloring for active stack dimensions. - The active node respects now a node radius by default and is scaled to 1.5x its size. This behavior can be disabled using the "Radius adaptive active node" checkbox in the "View settings" tab. - Catalog export: use global neuron name for sorting and display by default. - Catalog export: support for multiple neurons per panel has been added (separate from pinned neurons). The export dialog contains now a "Skeletons per panel" input field. Essentially, the displayed skeletons can bow be iterated in batches. - Catalog export: individual skeleton panels can now also be exported as PNG instead of SVG, which reduces the file size, export time, parsing time. Plus it allows for an exact copy of what is shown in the 3D Viewer. - Catalog export: in orthographic mode it is now possible to export a scale bar on either none, the first or all exported panels. - If the estimated size of the tiles to load for a Z plane exceeds 100 MB, users are asked for confirmation. Connectivity matrix: - Connector node filters can now be applied using the funnel icon in the widget title bar. - The new "Groups" tab allows to group rows, columns or both by their displayed name. - State saving is now supported. Reconstruction sampler: - Different leaf handling strategies are now available to be selected for a sampler. The behavior so far (and current default) is to just ignore leaf segments that are shorter than the interval length minus the error margin. Alternatively, it is now possible to merge the leaf segment into the last interval, to create new shorter intervals for the leaf segments or, combining both, it is possible to try to merge it into the last interval and if that's not possible (e.g. on a small twig with no previous interval on the same segment), then create a new short interval. This option is available in the Sampler tab. - Both the domain table and the interval table now show the cable length of each domain and interval in nanometers, respectively. Additionally, the interval tab also show the aggregated cable length of all completed intervals. Tracing layer: - The new option "Update tracing data while panning" allows to configure weather the tracing data on the layer will be updated when the view is panned around. - A set of new options allows now to configure a "tracing window", which will restrict tracing data loading by allowing it only in view centered rectangle. Width and height can be configured independently. This is useful for remote review and tracing. - A new option to show only the N largest skeletons in a field of view is now available for the layer settings (and the API). Miscellaneous: - The behavior of the Ctrl modifier on section navigation with , and . can now be inverted using the "Animate section change by default" option in the Settings Widget. - Connectivity widget: annotations can now be used for additional filtering per partner table. - Split/merge dialog: the node count of the individual parts is now shown when hovering over their cable length information. - Review widget: the user who created the last node of each segment is now displayed in the review table. This allows to focus review on segments not created by oneself. - A skeleton cable length limit can be set so that a warning is displayed if a change to the skeleton morphology results in a cable length larger than the limit. This is available in the Warnings section of the Settings Widget. - Node filters: if a neuron name is provided for a rule, the rule is now valid for all neurons with neuron names that include the provided name and not only exact matches. - Neuron name display: neighboring duplicate name components are now removed by the default. This setting can be adjusted from the Annotation sections in the Settings Widget. - Boolean parameters for API endpoints are no case-insensitive, allowing the use of regular boolean values in requests from Python. - CLI exporter: the new --excluded-annotation parameter can be used to exclude neurons from the export based on annotations. - CLI exporter: placeholder nodes are now exported as completely new skeletons that are not linked to their original skeleton, unless it is part of the set of exported skeletons or the --original-placeholder-context flag is provided. Bug fixes --------- - Measurements table: column headers in CSV export are now quoted. - Export management command: the default output filename can be used again. - Export management command: class instances and links of skeletons and neuronsa are now exported alongside treenodes. - Neuron name service: missing naming components don't lead to removal of all whitespace between neighbors anymore. - Initial skeleton coloring of merge dialog when merging from smaller into larger skeletons is fixed. - 3D viewer: refreshing the active skeleton does not refresh all skeletons anymore. - 3D viewer: connector restrictions like "show only shared connectors" now respect the pre/post visibility toggles in the Selection Table. - 3D viewer: the initial text scaling for label text is now correctly set again. - Reconstruction sampler: during interval creation preview, only intervals from the currently active domain are now shown. - Graph Widget: when subscribed to other widgets, their skeletons are not removed anymore from the Graph Widget when the other widget is closed. - Neuron Search: annotation data range can be used again. - The Strahler number computation no correctly increases the Strahler number when two more children have the local maximum number rather than requiring all children to share the same number. - Radius editing: using undo (Ctrl + Z) after editing the radius of a node works now without an error message. API changes ----------- Additions --------- - `POST /{project_ids}/connectors/links`: Accepts the same parameters as the GET variant, but allows for larger skeleton_ids list. - `POST /{project_ids}/skeletons/in-bounding-box`: Accepts the same parameters as the GET variant, but allows for larger skeleton_ids list. Modifications ------------- - `GET /{project_id}/skeletons/in-bounding-box`: The `min_nodes` and `min_cable` parameters can be used to further filter the result. The `src` parameter can be 'postgis2d' and 'postgis3d', with the former being the default spatial query type. The `volume_id` parameter can optionally be used to return the skeletons in the bounding box of a specific volume, alternative to explicit bounding box. Optionally, the `skeleton_ids` parameter can provide a list of skeletons to test for intersections. Without it, all skeletons in the project are considered. - `GET /{project_id}/skeletons/{skeleton_id}/review`: The user ID of each node is now returned as well. - `POST|GET /{project_id}/node/list`: Offers a new optional parameter "n_largest_skeletons_limit", which can be used to constrain the returned neurons to only those of the N largest skeletons in the result set. - `POST /{project_id}/skeleton/connectivity_matrix`: The new parameter 'with_locations' includes more data in the result set. Each connector and its contributions to the link count is returned as well. - `GET|POST /{project_id}/skeletons/compact-detail`: The new parameter 'format' can now be used to returned the skeleton data in different formats. Supported are 'msgpack' and 'json'. - `GET /{project_id}/skeletons/{skeleton_id}/compact-detail`: The new parameter 'format' can now be used to returned the skeleton data in different formats. Supported are 'msgpack' and 'json'. - `POST /{project_id}/treenodes/compact-detail`: The `treenode_ids` parameter is now optional and two new parameters can be used instead: `label_ids` and `label_names`. They can be used to constrain the result set by their labels. This effectively allows querying treenodes and skeletons based on linked labels. - `GET /{project_id/samplers/{sampler_id}/domains/`: Returns now also end nodes for each domain. Deprecations ------------ None. Removals -------- None. -----BEGIN PGP SIGNATURE----- iQJIBAABCAAyFiEE0ZcfpSuTdC1Kl2UqCBqeIVvdIIMFAltQESoUHHRvbUB2b29k b28tYXJ0cy5uZXQACgkQCBqeIVvdIINXeBAApVN73ZS36c0hAQI05KwXKR6ol2lI IRyOMiXAB8EEa8pfnjKQSuaIe0UE5H0F6DxCP68NTlaZv4K69er/m0CqqoDhDSrv e3qnVqX5LwywEtKpfoWPl3avIcVR72NgIlcQtavEhyKsDhHiucYjQdYaaEJioWmo 9Z1TftS7hIdosdnmwtrbu6Jz2MieD2cgdoi+0/Jj0kY2zdtVO2sfvyCrGcU1I5Jg Hc5JwogFluJCoUmEbFwL0+FWyDYoWS5MHol5/ijr6hjy2I6TJOJ4A7yH3e0WV9/0 riWlnYEUsF6S5kWqPg66eekYT9AKddafD09dA/G4500rw4fJCR0VNOmmt5UfbgCN A8J6+2+QwAni6iO6yOyTVUoi1swZloYDf1V0p0wRgBSnMVw4Tf0GAayNDhk4JtCd O9SA/DSKzZ/VltD+uzOG8JRpLifNwJsz9vfkBf1euEYRdOwtg+9g+J7yGS6OXyFl mUkBC8u0WgYz3ykW8YLGHjW3kYoJZIDKyzonbjTCzr+QZpE4zxGzirYYjBxf02sF QxkKcJlkNlPx97/6BqJbU+s52ZV23s0SURil7bFC99O854jIrLyZi7Umlau5fHNF QstCoHMPsgD13Ez1HfI+HdsXDLh0faCy2WHDJqfzpUdBKdiA14L8Ath+CKQPwl85 bkqPJEz3DwaiGMM= =ygOb -----END PGP SIGNATURE----- | 19 July 2018, 04:18:50 UTC |
| refs/tags/2018.04.15 | 2018.04.15 | 477b88f | 2018.04.15 ========== Contributors: Albert Cardona, Andrew Champion, Chris Barnes, Rob Court, Tom Kazimiers Notes ----- - Requires a virtualenv update. - A new management command "catmaid_find_node_provider_config" is available, which can be used to compare different node providers on existing data, which is useful to configure the NODE_PROVIDERS setting. - The Docker images now support the options CM_HOST and CM_PORT to configure where uwsgi is listening. - When using the Javascript console, node positions returned from tracing overlays are now in project space coordinates (physical nm), not stack space voxel coordinates. Transformation to project space is no longer necessary. - Postgres 10+ is now required. Features and enhancements ------------------------- Layouts: - A new "Layouts" menu is shown in the top bar when a project is opened. It allows to save the current window layout under a name, it provides an option to close all widgets and will show all available layouts as menu entries. - Layouts store window arrangement, window sizes, tabs and subscriptions. - Saved layouts can also be manually configured from the "Custom layouts" setting in the Settings Widget. - Tabbed windows are now supported in layout specs by using "t([a, b, c])" where a, b, c or any other number of elements can be children of the tabbed window. Landmarks: - Support transformation of nodes that cross space between landmark groups and even reach into target groups. This allows to e.g. transform skeletons that cross the midline. Doing this is enabled by default, but can be disabled through the "Interpolate between groups" option. - Virtual transformed skeletons are now also shown on a separate layer in all open Stack Viewers. Nodes of those skeletons can currently not selected. To disable the Landmark Layer, uncheck the "Show landmark layers" checkbox in the Display tab's button panel. - The new "Edit landmark" tab provides a simpler interface to add new landmark locations to landmark groups. If the option "Update existing landmark locations" is selected, new landmark locations will replace existing ones shared between the provided landmark and the selected group. The lower section of this tab allows to edit links between landmark groups, which can be used for rule based display transformations. - As an alternative to selecting a target landmark group explicitly to create a display transformation, it is now possible to instead select a target relation in the Display tab. Doing so will automatically create all display transformations from the source group to all landmark groups transitively linked to the source group using the selected relation. The reciprocity of relations is respected. - The new "Create groups" tab provides an option to create landmark groups along with required landmarks from the bounding boxes of two volumes. This allow to quickly create simple landmark group mappings. - The color and extra scaling for nodes on Landmark Layers can be adjusted from the widget. - All 3D Viewers are now enabled by default as transformation display target. - State saving is now supported. 3D Viewer: - A scale bar can now be displayed when in orthographic mode. The scale bar can disabled via a checkbox in the View Settings tab. - PNG and SVG exports offer now a filename input field. - Loaded volumes are now stored along with their styling in the widget state. - Landmark groups are now show with landmark name labels. This can be disabled from the landmark menu. - Text scaling can be adjusted from the View tab. - The width and height of animation exports are now restricted to even numbers. This is required by the H264 codec we refer to in our documentation. Graph widget: - The old "Graph" tab was split into two: "Nodes" and "Edges", each with the corresponding functionality. - New feature: color edges with the same color as the source node, the target node, or the general color specified in the "Properties" menu (from the "Main" tab). See the "Edges" tab. - New feature: change the arrow shape to a circle, diamond, tee, etc. The new "Set" button in the "Edges" tab applies the change to selected nodes. - New feature: the new "Selections" tab can record sets of nodes, stored as a named selection. Then these can be selected or deselected. The "Select all" button selects all nodes from all created selections. - Basic state saving is now supported. Reconstruction Sampler: - Intervals are now displayed with only two colors by default, it makes distinguishing many intervals easier. The previous multi-color mode can be reactivated from the preview window. Tracing general: - The settings widget allows now to configure a "fast split mode" and a "fast merge mode" to allow particular groups of skeletons to be split and merged without confirmation. Similarly to Visibility Groups, these Fast Split/Merge Groups can be defined in terms of a universal match (all skeletons), a required meta-annotation or a creator ID. In fast split mode, all annotations from the split skeletons are copied over to the split off part. In fast merge mode, all annotations are taken over from a skeleton merged in without confirmation. - The `P` shortcut (peek) will now show the closest skeleton to the cursor in all open 3D Viewers. To show the active skeleton use `Shift + P`. - A move/navigation mode can now be used using the new (third) button in the tracing tool bar. If enabled, no mouse based node actions will be performed anymore. Left mouse button clicks/movements are handled like right mouse button clicks/movements. - The Split Neuron Dialog has now "select all" checkboxes for annotations. Statistics widget: - Statistics widget: The new option "All" in the time unit selection control allow to aggregate user data for the whole time range. - The number of newly created treenodes is now displayed alongside the cable length in the contribution table. - Each user can now be included in an aggregate statistics row at the end of the table by checking the checkbox in front of the username. - Add extra Refresh button to top bar. Volume widget: - The new link "List skeletons" in each volume table row allows to open a new Selection Table containing all skeletons the bounding box of the respective volume intersects. Due to large numbers of skeletons in bigger volumes, this is currently mainly useful for smaller volumes. - When creating box volumes, the new button "Define cube at current location" allows to conveniently create a cube with a configurable edge length at the current location. Miscellaneous: - Basic Search: allow search for treenode IDs and connector IDs. - Project administration: selected projects can now be exported as JSON or YAML file using the respective action from the drop-down menu. - In addition to the '/apis' endpoint, the API documentation is now also available as part of the general documentation. - Connectivity Widget: partner header indexes can now optionally be replaced with the neuron name and rotated by 90 degrees. - The Keyboard/Mouse Help Widget has now a text filter, which allows to show only items containing a particular text. - The Tracing Overlay has a new setting "Allow lazy node updates", available in the Settings Widget. If enabled (default), stack viewers can skip node updates if a change didn't occur in the Viewer's field of view. This is useful when e.g. the Connector Viewer is open while tracing, because not all viewers get update due to the addition of a node. - Selection Table: Skeletons can now be imported from CSV files. - The status bar shows now both stack space and project space coordinates of the mouse cursor. - The skeleton projection layer works now with orthogonal views. - Detailed review colors are now enabled by default. To get the old behavior back, adjust your settings (admins can do this for the whole project or server). - Stacks can now be created whose planar axes have anisotropic resolution. The stack viewer will display these stacks correctly by scaling tiles separately along each axis. The tracing overlay is also compatible with these stacks in all orthoviews. - Added H2N5 tile source type. - Due to the new skeleton summary tables, some APIs are much faster now: 1. Obtaining review info skeletons with /{project_id}/skeletons/review-status, 2. API and connectivity information through /{project_id}/skeletons/connectivity, 3. Listing skeletons with a minimum node count with /{project_ids}/skeletons/ 4. Getting skeleton node count with /{project_id}/skeleton/{skeleton_id}/node_count. In consequence the following widgets became faster too: Connectivity Widget, Selecting skeleton counts in the Statistics Widget, Review count based coloring (e.g. in Graph Widget). Opening the Merge Dialog is also faster due to this change. Bug fixes --------- - Reconstruction Sampler: 3D visualizations for interval preview and color mode were sometimes wrong and showed additional intervals. This is fixed now. Actual interval boundaries were not affected and are correct. - Reconstruction Sampler: Individual intervals are not silently deleted anymore if referenced start or end node is deleted. As consequence interval start and end nodes can't be deleted anymore. - Measurement table: no error is shown anymore after merging two listed skeletons. - Radio button drop-downs and checkbox drop-downs now hide on a mouse click outside of the control. - Review: fix node selection error appearing during review of some virtual nodes. - Tracing layer: when trying to create a second presynaptic node to a connector, a warning is now shown instead of a full error dialog. Also the previously created target treenode isn't created anymore in this case. - Tracing layer: prevent browser context menu on tracing overlay right click. API changes ----------- Additions --------- - `POST /{project_id}/treenodes/compact-detail`: Retrieve treenode information for multiple nodes in the format of regular node queries, accepts a parameter "treenode_ids". - `GET /{project_id}/treenodes/{treenode_id}/compact-detail`: Retrieve treenode information for a single node. - `DELETE /{project_id}/landmarks/{landmark_id}/groups/{group_id}/`: Delete landmark location links to the same locations from a landmark and group. - `PUT /{project_id}/landmarks/groups/links/`: Add new links between groups, e.g. "adjacent_to". - `DELETE /{project_id}/landmarks/groups/links/{link_id}/`: Delete a single landmark group link. - `GET /{project_id}/landmarks/groups/{landmarkgroup_id}/transitively-linked`: Get a list of landmark groups that are linked to the referenced group using a passed in relation, respects reciprocal relations. - `POST /{project_id}/landmarks/groups/materialize`: Create pairs of landmark groups along with their landmarks based on a simple description. - `GET /{project_id}/skeletons/cable-length`: Get the cable length for multiple skeletons using the skeleton_ids parameter. - `GET /{project_id}/skeletons/{skeleton_id}/cable-length`: Get the cable length for a single skeleton. - `GET /{project_id}/skeletons/in-bounding-box`: Get IDs of all skeltons that intersect with the passed in bounding box. Modifications ------------- - `POST /{project_id}/annotations/query-targets`: Accepts now a "annotation_reference" parameter which can either be 'id' (default) or 'name'. If it is set to 'name', all annotation references in annotated_with, not_annotated_with and sub_annotated_with are interpreted as annotation names instead of IDs. - `POST /{project_id}/skeleton/split`: Returns now also the split location as fields x, y and z. - `POST|GET /{project_id}/node/list` offers a new optional parameter "with_relation_map", which controls which relation map information is returned. Can be 'none', 'used' and all with 'used' being the default. - `GET /{project_id}/landmarks/groups/`: Accepts the new optional parameter "with_links", "with_names" and "with_relations", to include links between landmark groups along with a list of linked landmark names and a map of used relations - `GET /{project_id}/landmarks/groups/{group_id}/`: Accepts the new optional parameter "with_names" to include landmark names along with linked landmark locations. - `GET /{project_id}/stats/user-history`: Returns actual node count in "new_treenodes" field, cable length is returned in "new_cable_length" field (previously new_treenodes).

| refs/tags/2018.02.16 | 2018.02.16 | 6f33ead | 2018.02.16 ========== Contributors: Andrew Champion, Albert Cardona, Chris Barnes, Tom Kazimiers Notes ----- - Three new OS package dependencies have been added (due to a Django framework upgrade), make sure they are installed: sudo apt-get install binutils libproj-dev gdal-bin - Python 3.6 is now supported. Make sure to update your settings.py by replacing the line COOKIE_SUFFIX = hashlib.md5(CATMAID_URL).hexdigest() with the following line: COOKIE_SUFFIX = hashlib.md5(CATMAID_URL.encode('utf-8')).hexdigest() - A virtualenv upgrade is required. To correctly install one updated dependency, the django-rest-swagger Python package has to be removed first from from the virtualenv, before the virtualenv is updated: pip uninstall django-rest-swagger pip install -r requirements.txt - `requirements` files now inherit from each other: `-test.txt` includes the production requirements, `-dev.txt` includes test (and therefore production) and doc. - CATMAID extensions no longer require users to manually edit their `INSTALLED_APPS` in `settings.py`. Remove if they are already in use. - The NODE_PROVIDER settings variable (settings.py) is replaced with the NODE_PROVIDERS variable. The new variable takes a list of node provider names, which are iterated as long as no result nodes are found. Replace the former single string value with a list with this name as single element, e.g. if the current setting reads NODE_PROVIDER = 'postgis2d', replace it with NODE_PROVIDERS = ['postgis2d']. - Three new types of cache backed node providers have been added: cached_json, cached_json_text, cached_msgpack. Tests suggest that cached_msgpack is the fastest. Features and enhancements ------------------------- Reconstruction Sampler: - 3D previews now allow to use a white background and toggle meta spheres. - To match a given interval length, the Reconstruction Sampler will now create new nodes during interval creation. This allows better sampling on long straight lines without intermediate nodes. To disable this behavior uncheck the "Create bounding nodes" setting. Newly created nodes are automatically labeled with the "sampler-created" tag. - By adjusting the new interval "max error" setting, it is possible to only create bounding nodes (if enabled) if the closest existing node is farther away from the ideal location than the max error value. This allows better reuse of existing nodes. - Created interval boundary nodes are also automatically deleted on sampler removal, if possible. If a created node has not been altered in any way during its life time and it still forms a straight line with its parent and single child, it can be removed. Otherwise the node is kept. - A new "Partner" step has been added. After a connector is selected at random, users are now asked to add all partner nodes to the synapse and let the widget choose a partner site for them. - Sections that should be interpolated (e.g. because of large tracing data shifts due to image data shifts) are now respected and not over-sampled anymore. - Completed intervals can now be optionally excluded from random selection. Node Search: - Tagged connector nodes are now shown in search results. - Annotation search results allow now to open the Neuron Navigator page for the respective annotation. Graph Widget: - It is now possible to show links of all connector types. By default, only synaptic connectors are available, but this can be changed using the "Link types" drop down control in the Graph tab. There also the edge color for particular link types can be set. - The edge color button in the option dialog has been replaced with a link type drop down which allows to set color and visibility per connection type. 3D Viewer: - Stored interpolatable sections are now loaded by default. Additional project space sections can be configured from the Skeleton filters tab. - Custom tags can now also apply to predefined labels like TODO or uncertain_end. Miscellaneous: - The maximum number of frames per second rendered by a stack viewer window can now be adjusted through the Settings Widget > Stack view > Max frames per second. - The Open Widget dialog is now only opened with Ctrl + Space when no other keys are pressed. This allows to use key combinations like Ctrl + Shift + Space + > to browse smoothly through the image stack while hiding the tracing layer. - The active node can now be moved in Z by holding the `Alt` key and using `,`/`.`. The stack viewer follows the node. - Filters: a Reconstruction Sampler Domain node filer is now available. The required node ID can be optained from the Reconstruction Sampler Widget. - Neuron History: a lower and upper bound for the time window in which changes are respected and counted can now be set. - On CATMAID front-pages (project overview) the keys 0-9 can now be used to open the n-th stackgroup or stack, stackgroups have precedence. - Sections in which nodes should be interpolated for various displays can now be persisted in the database using the "interpolatable sections" data model from the admin interface. Bug fixes --------- - Reconstruction sampler: Strahler shading color updates work now reliably. - Reconstruction sampler: connectors in neighboring intervals are now not included anymore in connector listing. - 3D Viewer: SVG export styles are correctly applied again, the exported data isn't transparent anymore. - 3D Viewer: custom label matches are now always given precedence when multiple labels are matched on a node. API changes ----------- Additions --------- - `GET /{project_id}/useranalytics`: Replaces `GET /useranalytics`. Modifications ------------- - `GET /{project_id}/samplers/`: Accepts now also a boolean with_intervals parameter to return information on each instantiated interval in each returned domain. Implies with_domains. - `POST|GET /{project_id}/node/list` offers a new optional parameter "src", which can be used to override the node provider selected by the back-end. - `POST|GET /{project_id}/node/list` offers new options for the optional parameter "format": "gif" and "png" to return an imageof the tracing data. Deprecations ------------ None. Removals -------- - `GET /useranalytics`: Has been replaced with `GET /{project_id}/useranalytics`. | 16 February 2018, 23:42:58 UTC |
| refs/tags/2017.12.07 | 2017.12.07 | 63e464f | 2017.12.07 ========== Contributors: Albert Cardona, Andrew Champion, Chris Barnes, Tom Kazimiers Notes ----- - PostgreSQL 9.6 and Postgis 2.4 are now required. - A virtualenv update is required. - New settings field: CROPPING_VERIFY_CERTIFICATES. This controls whether SSL certificates should be verified during cropping and defaults to True. - The NODE_LIST_MAXIMUM_COUNT setting can now be set to None, which disables node limiting. If node count limiting isn't really needed in most cases, this can slighly improve query performance. - The file `UPDATE.md` will now list all administration related changes for each release, including required manual tasks. These changes also continue to be part of this change log. - Requires running of: manage.py catmaid_update_project_configuration - Tracing data is now by default transmitted in a binary form, please make therefore sure your web-server applies GZIP not only to the "application/json" content type, but also to "application/octet-stream". For Nginx this would be the gzip_types setting. Features and enhancements ------------------------- Node filters: - A new node filter called "In skeleton source" has been added. This allows to add a filter which only allows nodes of a particular set of skeletons, accessed through a skeleton source. This can be useful to look at connectivity of a particular set of neurons. It can of course be combined with other filters like volume intersection. - New filter: Pruned arbor, which keeps the arbor proximal to the (tagged) cut points, discarding distal subarbors. Connector table: - Node filters are now supported. - Attachment connectors are now supported. 3D viewer: - Landmarks and landmark groups can be displayed. Similarly to volumes individual groups can be selected and adjusted through the "View settings" tab. Apart from the color and mesh-faces option for groups, it is possible to scale landmarks. - All visible skeletons can now be exported as Wavefront OBJ file. Each skeleton will be rendered as a separate group, colors are preserved and written out as material file (MTL). Both files can be compressed as ZIP file on the fly and it is possible to generate a simple line based export as well as a mesh based representation using a user definable radius. The generated ZIP file can be used with services like augment.com. Neuron history widget: - A user filter can now be applied through the respective checkbox drop down element. If at least one user is selected, only events caused by those users are respected. New connector types: - Two new connector relations are available: attached_to and close_to. Like other connector relations, they can be used to link treenodes to connectors and can be used with the help of Alt + Click context menu when a treenode is selected. They are available as "Attachment" and "Close to". - If If a connector has at least one attachment relation is viewed as "Attachment connector" and additional clicks with such a connector selected will create "Close to" edges. - To add more information about the nature of an attachment, the connector should be labeled, e.g. as "vesicle". Connectivity Widget: - All skeletons linked through a attached_to -> connector -> close_to relationship are now shown in a separate table if the "Show attachments" option is enabled. Export management command: - The export management command will now also export meta-annotations when the --annotation option is set. All meta-annotations of annotations directly linked to the exported neurons are exported, too. - Users referenced by any of the exported objects are now also exported automatically. This can be disabled using the --nousers options. - User references are now stored as usernames rather than numerical IDs. This removes the requirement of always also exporting user models, because users can be mapped based on their usernames. Import management command: - The new --map-users option allows to map users referenced in the imported data to already existing users in the database. This makes updating existing databases easier and removes the de facto import data requirement to contain user models. By default --map-users is not set. - The new --create-unknown-users option will instruct the importer to create new inactive user accounts for users that aren't included as objects in the imported data. If user mapping is enabled, accounts would only be created for users that can't be mapped and are also not included in the import data. By default --create-unknown-users is not set. - Imported class, class instance and relation objects are skipped when existing objects in the target project have the same name. This makes merging of projects also possible for semantic data (e.g. annotations, tags). The only exception are neuron class instances, where two different objects are allowed to have the same name. - The importer now won't keep the IDs from spatial objects in the input source, but will instead always create new objects. This ensures no existing data is replaced and allows importing different sources into a single CATMAID instance. If the original IDs have to be used, the ``--preserve-ids`` option can be used. This is done for treenodes, connects, and their links. Miscellaneous: - Users can now choose alternative markers for connector nodes, which do not obscure the object being annotated: this encourages manually annotating synapses etc. in a manner which is more comparable with automated detections - Exported sub-stacks now include the Z resolution. - Added table of reviewers vs number of nodes reviewed to the "Summary Info" in the Selection Table widget. - Synapse distribution plot: global and single-axis zoom and pan are now supported. - Neuron dendrogram: nodes linked to connectors (synaptic sites) can now be highlighted. - Tracing layer: cached tracing data is now used by default when showing sub-views of previously loaded data. This is useful for e.g. quickly zooming in. Like with the regular node cache, views not used for one minute will be thrown away. - All users can now view their user analytics plot with the help of the Project Statistics widget. - The NRRD file export can now transform from FAFB v14 into template brain space. - Synapse Fractions: the button "Group all ungrouped" will move all skeletons that are not part of a group already and not part of "others" into a new group. To also include skeletons in "others", use a synapse threshold of zero in the "Filter partners" tab. - Selection Table: Open/Save (JSON) does now preserve the order of skeletons. - Tracing data should load faster due to spatial query improvements and reduction of transferred data. The tracing layer transfers data now in binary by default, which can be adjusted in through the tracing layer settings. - The catmaid_setup_tracing_for_project management command does not require a --user argument anymore. If not provided, the first available admin user will be used. Bug fixes --------- - 3D Viewer: the visibility of skeletons with connector colors the same as the skeleton can now be controlled correctly. - Selecting nodes explicitly with multiple stackviewers open (e.g. by Shift-Click in the 3D Viewer) sometimes raised an error about not being able to find the selected node. This is fixed now. - Entries in the Treenode Table can now be correctly sorted by date. - Cropping tasks can now work with HTTPS URLs. - Graph widget: new skeletons can now be added again after individual skeletons have been split. API changes ----------- Additions --------- - `POST /{project_id}/nodes/location`: Get the location of multiple nodes, expects a `node_ids` parameter. - `GET /{project_id}/connectors/` now provides a new API to query connectors directly and not only links. The previous API is available as `GET /{project_id}/connctors/links/` (see below). - `GET /{project_id}/skeletons/{skeleton_id}/neuroglancer`: Export a morphology-only skeleton in neuroglancer's binary format. Modifications ------------- - `GET /{project_id}/connector/user-info` has been replaced with `GET /{project_id}/connectors/user-info`. Functionality is the same. - `GET /{project_id}/connectors/` has been replaced with `GET /{project_if}/connectors/links/`. Functionality is the same. - `POST /{project_id}/node/list` offers a new optional parameter "format", which is set by default to 'json', but can be set to 'msgpack' to use msgpack binary encoding of the result. Deprecations ------------ None. Removals -------- None. | 07 December 2017, 05:30:27 UTC |
| refs/tags/2017.10.02 | 2017.10.02 | e66585f | 2017.10.02 ========== Contributors: Chris Barnes, Dylan Simon, Albert Cardona, Andrew Champion, Tom Kazimiers Notes ----- - A virtualenv update is required. - This release adds optional statics summary tables, which can increase the performance of project/user statistics significantly, but statistics will also be correct without them. The additional table keeps aggregated information about various user actions. To initialize this table, the following manangement command has to be run after the migration: ./manage.py catmaid_populate_summary_tables To maintain good performance, this command has to be run regularly, e.g. through a cron job or Celery every night. Because summary updates are incremental by default, they don't take much time to update. - CATMAID's Docker images changed: The existing `catmaid/catmaid` image is now only a base image that is used for a simple standalone demo image, available as `catmaid/catmaid-standalone`. Additionally, the base image is used in a new docker-compose setup, which can be used if persistent data is required. The documentation has been updared with all the details. - The Docker default port is now 8000 for both regular setups and docker-compose setups. - The data view "legacy project list" has been renamed to "simple project list". It now supports separate project title and stack title filters, which can be preconfigured using the data view config options "projectFilterTerm" and "stackFilterTerm". For both simple terms and regular expressions can be used. The filter input boxes can optionally be hidden by setting the "filter" config property to false. - Running periodic tasks is now easier and a default setup for cleaning up cropping data at 23:30 and update tracing project statistics at 23:45 every night is now available. All it needs is to run a Celery worker and a Celery beat scheduler. The documentation has more details. - The cropping output file file name prefix and file extension can now be specified from settings.py. The defaults are: CROPPING_OUTPUT_FILE_EXTENSION = "tiff" CROPPING_OUTPUT_FILE_PREFIX = "crop_" - CATMAID can now make use of a ASGI server to utilize WebSocket connections. Such a server (e.g. Daphne) needs to handle URLs that start with /channels/. Currently only messages can be updated this way, which already removes many requests for setups with many users. This allows for instance an immediate feedback after a cropping a sub-stack finished without requiring the client to check for new messages every minute. Features and enhancements ------------------------- Project/user statistics: - The widget should now be much faster. - Import actions are not counted anymore by default. The "Include imports" checkbox can be used to change this. - State saving is now supported. Neuron history: - Events by different users are now collected in separate bouts to attribute parallel user activity. To restore the previous behavior (users are ignored) the "Merge parallel events" checkbox can be checked. - State saving is now supported - Individual neurons can be removed with the help of an "X" icon in the firs column. - A "total time" column has been added, which aggregates time across all active bouts formed by both tracing and review events. Since events are binnned in bouts, the total time is not just the sum of both tracing time and review time. Node filters: - A Reconstruction Sampler interval can now be used as a node filter. This allows e.g. reviewing only an interval or look only at the connectivity of the interval. Graph Widget: - Edge labels can now take different forms and can be configured in the properties dialog. There are two new label options available: "Fractions of outbound connections" and "Fractions of inbound connections". Instead of an absolute number they display the relative fraction. This works for both regular connections and connections involving groups. Reconstruction sampler: - Intervals for a particular interval length can now be previewed before creating a new sampler. To do so, use the "Preview intervals" button in the Sampler tab. - Interval reviews can now be initiated directly from the interval step table. It will open a new review widget with pre-set interval filter and added skeleton. The same is possible from the synapse workflow step using the "Review interval" button. Layouts: - The Stack View section of the Settings Widget allows now the configuration of a list of default layouts that can be applied to newly opened stacks and stack groups. Layouts are useful for having a reasonable default configuration of a newly opened CATMAID workspace including stacks and stack groups. - Layouts mimic nested function calls and are constructed from v(a,b) and h(a,b) elements for vertical and horizontal splits, o(a) for optional windows, where a and b can each be other v() or h() nodes, one of [XY, XZ, ZY, F1, X3D] or any quoted widget handle (e.g. "neuron-search", see Ctrl + Space). At the moment, in o(a), "a" can't be XY, XZ or ZY. To reference the 3D Viewer use X3D. - By default only one layout is available: organize XY, XZ and ZY in four quadrants using one additional window (if non available the help page). This is its specification: h(v(XY, XZ), v(ZY, o(F1))). With h() and v(), horizontal and vertical splits are declared, respectively. With o(F1) a help window will be opened as fourth window if not already another window exists. - Useful for organizing orthogonal views in a custom way and to create default workspaces. For instance, to always open a Neuron Search widget right to the a single XY view stack, the layout can be used: h(XY, "neuron-search"). CATMAID extensions: - As well as supporting standalone 3rd party static files, CATMAID now supports fully-featured extensions, which can include database models, API endpoints, and tests as well as static files. - CATMAID extensions are Django apps which follow a particular layout, and can be installed with `pip` - The goal is for CATMAID extensions to be reusable and interoperable between versions and installations of CATMAID, reducing the need to fork it and keep the fork updated in parallel. - More details can be found in the docs. 3D viewer: - Volumes can now be filtered in the volume drop-down menu with the help of a built-in text box. Miscellaneous: - The Open Widget dialog now displays a table that includes more information on widgets. Instead of the previously used auto-completion this table is now filtered. - If multiple tile layers are used, the stack viewer layer settings (blue white box in lower left corner) allow to set which stacks should be respected if broken sections are skipped. This can be done through the "Skip broken sections of stacks" drop-down menu. Whether layers added after the first layer should be respected by default when checking for broken sections can be set in the Settings Widget in the "Stack view" section. - The dialog to add a new annotation displays now the existing annotations as well. - Tabbed windows: changing window aliases are now reflected in tab headers. - The performance of node creation and deletion operations has been improved by preventing full node updates after these operations. - Widgets with state saving support now also support removing previously saved states through a button in the widget controls available through the window icon in the widget title bar. - The Selection Tool (the first icon in the top bar) has been removed, because it didn't provide any functionality. It is replaced by an icon to show the "Open Widget" dialog, which can otherwise be shown using Ctrl + Space. - When splitting a skeleton on a virtual node, the virtual node will now only be instantiated if the user presses OK in the dialog, canceling won't cause a change of the virtual node. - The default for hiding tile layers if the nearest section is broken (instead of showing the next available) can now be configured from the Settings Widget in its Stack View section. - `plotly.js`, a d3-based plotting library, is now available within CATMAID, making it much easier to generate common plots. Bug fixes --------- - Review widget: moving in reverse direction from a virtual node doesn't show error anymore. - Review widget: the Shift + Q key combination to select the next unreviewed node in downstream direction is respected again. - Review widget: Shift + W and Shift + Q work now correctly if the first unreviewed node is a virtual node. - Key combinations involving the Alt key were not respected on Mac OS. This is fixed now. - Reconstruction sampler: the list of connectors in the selected interval of the synapse workflow step is now complete when refreshed. - 3D viewer: the error shown when changing skeleton properties with an active connector restriction is fixed. - The neuron history widget now calculates both tracing time and review time correctly. - 'Peek skeleton' (P key) works again. - The Split Skeleton Dialog updates the embedded 3D view again after all skeletons are loaded. - Former partner nodes of deleted connector nodes can now be deleted without an additional tracing layer update. - The Skeleton Projection Layer can now use the skeleton source colors and other colors source again. - The simple front end data view's project filter works again - Skeleton source subscriptions: opting in and out of applying color changes in source skeletons to existing target skeletons works again. - Dragging nodes in stacks with smaller resolutions (larger nm/px) doesn't require large drag distances anymore, before the move is registered. - Node selection works now reliably with orthogonal views, including using the "G" key. API changes ----------- Additions --------- - `GET /{project_id}/samplers/domains/intervals/{interval_id}/details`: Get detailed information about a particular interval. - `GET /{project_id}/neurons/`: List all neurons in a project. Optionally, the parameters created_by, reviewed_by, from, to and nodecount_gt can be provided. Modifications ------------- - `POST /{project_id}/treenodes/{treenode_id}/info`: This API endpoint is changed to only accept GET requests. Using POST will raise an error. - `GET /{project_id}/stats/nodecount`: The response format changed. Now a dictionary mapping user IDs to node counts is returned. - `GET /{project_id}/stats/editor`: The response format changed. Now a dictionary mapping user IDs to the number of edited nodes is returned. - `GET /{project_id}/projects/export`: Stacks include now also their translation and orientation relative to project space. Deprecations ------------ - `GET /{project_id}/annotationdiagram/nx_json`: This API has a confusing name, because it uses 'annotation' differently than others. There are different APIs available to get skeleton IDs and treenode IDs. Removals -------- None. | 03 October 2017, 03:13:13 UTC |
| refs/tags/2017.07.28 | 2017.07.28 | f2c587c | 2017.07.28 ========== Contributors: Chris Barnes, Albert Cardona, Tom Kazimiers, Daniel Witvliet Notes ----- - Prepared statements can now also be used together with connection pooling. - A virtualenv update is required. - The following lines have to be removed from `settings.py`, import djcelery djcelery.setup_loader() INSTALLED_APPs += ("kombu.transport.django") BROKER_URL = 'django://' - Two new treenode and connector node providers have been added: postgis2dblurry and postgis3dblurry. They works like the regular postgis2d and postgis3d node providers except that they allow more false positives, because edges are only tested for bounding box intersection with the query bounding box. Depending on the dataset, this can help performance but might require a larger node limit. Features and enhancements ------------------------- Synapse Fractions: - New button "Append as group". Multiple neurons will be shown in a single column. - New UI functions to set the synapse confidence. - Default to Upstream (fractions for input neurons). - Shift-click to toggle selected state of partner neurons or groups, and then push 'J' to create a new partner group. - X axis labels can now be rotated, from the Options tab. - Node filters can now be applied to filter valid connector links. 3D Viewer: - New skeleton shading modes: * "Axon and dendrite": like the coloring mode "Axon and dendrite", but using shading like in the "Split at active node" mode. * "Single Strahler number": color branches of a specific Strahler number in full color, and darken everything else. The Strahler number is specified in the tab named "Shading parameters". * "Strahler threshold": color branches of a Strahler number equal or higher than the number specifed in the Stahler number field ("Shading paramters" tab) in full color, darken all others. When inverted, show in full color branches with a Strahler number strictly lower than the specified one. - The Z plane display now supports stack viewer layers. If multiple layers are shown in a stack viewer, its Z plane will render all visible layers on top of each other. Review widget: - Large neurons are handled better, rendering tables with many segments is now faster. - The set of displayed columns can now be constrained with the help of the new "Visible reviewers" setting in the widget. Available options are "All", "Team" and "Self". - A new option to automatically scroll the active segment into view has been added ("Scroll to active segment"). With this enabled (default), when a node of a segment of the reviewed skeleton is selected in the tracing layer, the review widget will scroll the segment into view. - State saving is now supported. Node filters: - A Strahler number filter has been added to only show nodes with a Strahler value below/same as/above a user defined number. Neuron Search: - It is now possible to use the "not" operator with neuron name and annotation search criteria. - Both neuron name and type columns can now be sorted. - Filters are now supported. Only neurons will be shown of which at least one node is in the node filter result set. Neuron History: - This new widget can be opened using Ctrl+Space together with the key "neuron-history" or through a button in the Neuron Navigator. - For all neurons added to this widget, time related information is presented. Currently, the following is calculated: Tracing time, review time, cable length before review, cable length after review, connectors before review and connectors after review. - The components that contribute to the tracing time can be adjusted with the "Tracing time" drop down menu. Reconstruction Sampler: - This new widget can be opened using Ctrl + Space and the keyword "reconstruction-sampler". It allows to target reconstruction effort based on the spatial sampling of a skeleton. This is mainly useful for large neurons that can't be quickly traced to completion. The widget is organized as a workflow that prevents skipping steps. - To keep track of reconstruction progress, a so called sampler is created for a skeleton of interest. This skeleton is typically the backbone of a larger neuron. The sampler keeps track of some global properties for the sampling. Once created, a sampler can be "opened" either by clicking "Open" or by double clicking the respective table row. Also note that with a sampler attached to a skeleton, the skeleton can not be deleted. If a skeleton should be deleted, delete its samplers first. - Once opened, a sampler allows creating so called sampler domains, which are regions on the skeletons which should in principle be considered for sampling. Topological and tag based definitions of sampler domains are possible. Created samplers can be opened through a click on "Open" or a double click on the table row. - Once opened, sampler domains can be further divided in so called sampler intervals. To do so the "Create intervals" buttons has to be pressed. These have initially all the same length (defined in sampler) and no branches. Intervals are meant to picked at random through the respective button. - With an interval selected, the goal is now to reconstruct it to completion with all branches and connectors. CATMAID will show a warning when moved out of the interval. The workflow page will show both input and output connectors. - As soon as the interval is reconstructed completely, a synapse can be picked at random from which the next backbone can be reconstructed. Once the backbone is found and reconstructed, the sampling can start over. Alternatively, another interval in the original skeleton can be selected at random. Miscellaneous: - Split/Merge dialog: the node count for both respectively remaining/new and remaining/old are now on top of the annotation lists. - The General Settings section of the Settings Widget now provides an option to disable asking for confirmation when the active project is closed. - Tile layers can now be configured to not automatically switch to the next accessible mirror if the present one is inaccessible. This is useful for some custom mirror use cases and can be set through the "Change mirror on inaccessible data" checkbox in the layer settings. - Empty neuron name pattern components are now by default trimmed automatically. Empty components at the pattern endings won't leave any white space behind. Empty components between other components are allowed one space maximum (if there were spaces before). The difference is visible e.g. in the Graph Widget. - URL-to-view links now allow selected connector nodes. - Adding a custom mirror will now by default disable automatic mirror switching of the respective tile layer. Custom mirrors often come only with a subset of the data, which currently triggers a mirror switch by default if some tile is not accessible. - The tracing layer is now faster with creating skeleton nodes, connectors and partner nodes by avoiding unneeded node updates. - Export widget: exporting neurons as NRRD files is now supported. The NAT R package is used for this. Check documentation for setup. - The tracing tool has now a button to refresh CATMAID's caches for neuron names and annotations. This can be used to update neuron names with components that were changed by other users. Additionally, such a cache update is performed automatically once every hour. - URLs to a particular view work now also with a location and a skeleton ID only rather than requiring a node ID always. - Using "Shift + x" and "Ctrl + x" will now activate a checkbox selection mode and the cursor turns into a crosshair. In this mode one can draw a rectangle everywhere on the screen and all checkboxes that are behind the rectangle will be toggled using "Ctrl + x" (turned on if off and vise versa) or checked with "Shift + x". Either releasing the drawing mouse click or a second "Shift + x" or "Ctrl + x" will deactivate the tool again. - All skeleton source widgets (typically those with a skeleton source drop-down menu) now support copy and paste of skeleton models. Pressing "Alt + Ctrl + c" in an active widget will copy its skeletons (along with colors) into a clipboard. Pressing "Alt + Ctrl + v" in another widget will then paste those models into the now active widget. - When using the Z key to create new nodes, existing nodes are not as easily selected from a distance anymore. Before, the radius around a click event was too large and the closest node around the click was selected. Other nodes will now only be selected if the mouse cursor is close to their circle graphic on screen. Bug fixes --------- - Graph widget: re-layout works again. - The Docker image can be used again without requiring a manual restart of the uWSGI server. - Zooming in using the "=" key and using Shift + Z to join and create nodes both work again. - Links inside the simple Search Widget can be clicked again. - Back-end calls with large parameter lists can be used again (e.g. review status in the Connectivity Widget). - Highlighted tags in the Neuron Dendrogram widget are now correctly displayed next to the nodes they belong to. Before, each tagged node had all selected tags shown next to it, regardless of whether it would be tagged with them. - 3D viewer: the textured Z section rendering in the 3D Viewer now respects the mirror setting from the tile layer. - 3D viewer: a memory leak in displaying Z sections with images has been fixed. This allows long continued Z section browsing without crashing. - 3D viewer: the accurateness of object picking on neurons and location picking on z panes has been improved. - Cropping image data works again. - Setting a stack viewer offset won't cause an error anymore. - User interaction without a reachable server (e.g. due to a disconnected network) doesn't lead to image and tracing data freezing anymore. - Pressing key combinations before the tracing layer has loaded is now handled more gracefully (no error dialog). - 3D viewer: the active node split shading can now handle changed virtual nodes to which it is lacking information and won't raise an error. - All newly opened widgets that support it, appear now in the "skeleton source" drop-down menus of all other widgets from that moment on. This was a problem mainly with Analyze Arbor, Measurements Table, Morphology Plot, Neuron Dendrogrm and Treenode Table. API changes ----------- Additions --------- None. Modifications ------------- - `POST /{project_id}/skeletons/import`: The new 'name' parameter can be used to set the name of a new neuron. - `POST /{project_id}/annotations/query-target`: A boolean 'name_not' parameter is now accepted to get results not matching the name passed in with the regular 'name' parameter. Also, an integer list parameter named 'not_annotated_with' is now supported. Like the 'annotated_with' list, it contains annotation IDs. Results will not have the annotations passed in with the `not_annotated_with` list. - `GET /{project_id}/skeletons/{skeleton_id}/compact-detail` and `GET /{project_id}/skeletons/compact-detail` Accepts two new parameters: with_reviews and with_annotations. To also return a list of reviews and a list of linked skeleton IDs respectively for each returned skeleton. - `POST /{project_id}/volumes/{volume_id}/` Individual fields can now be updated selectively. Only fields that are passed in as arguments will be updated. This allows for instance to only change the name of a volume. Deprecations ------------ None. Removals -------- None. | 28 July 2017, 04:18:28 UTC |
| refs/tags/2017.05.17 | 2017.05.17 | 9100eb4 | 2017.05.17 ========== Contributors: Andrew Champion, Tom Kazimiers Notes ----- - A virtualenv upgrade is required. To correctly install one updated dependency, the django-rest-swagger Python package has to be removed first from from the virtualenv, before the virtualenv is updated: pip uninstall django-rest-swagger pip install -r requirements.txt Features and enhancements ------------------------- Widget state saving: - Infrastructure has been added to store widget configuration client side in a browser cookie. This makes it easy to update widgets to support automatic saving and loading of state information. The automatic saving and loading behavior can be configured in the General Settings section of the Settings Widget. To explicitly save the state in a supported widget, the respective button available through the "Window Configuration" title bar icon can be used as well. - State saving support has been added for the 3D Viewer and the Connectivity Widget. Generic node filtering: - A generic user interface for filtering nodes is now available to widgets. If a widget supports it, the filtering user interface is available through the filter icon in the widget's title bar. - The user interface has a "Filters" tab which lists all active filters for a widget and a "Add filter" tab, which can be used to create new filter rules. - Filter rules select nodes that are kept, i.e. the filter application results in a list of nodes that match the filter expression. - Different filter types are available at the moment: Only end nodes, only tagged nodes, only nuclei, only a sub-arbor starting from a tag, tag defined region, created by user(s), node creation/edite time, binary split, axon, dendrite, synaptic connectivity and volumes. Some come with own user input elements, but all can optionally be applied to only a subset of skeletons. - Multiple filters can be combined, e.g. all branch nodes with a particular tag and end nodes. All filter rules are combined in a left-associative fashion and union and intersection can be used as operators. Connectivity widget: - Support for node filtering has been added, it can be configured through the filter icon in the title bar. All features listed under Generic Node Filters are supported. If a node of a skeleton from the top list doesn't match the filter expression, synaptic connections involving it will not be respected. Review widget: - Whether detailed review colors should be used is now persisted. - The checkbox "Save review updates" allows to disable sending review updates to the server. Ending review or closing the widget will cause all review updates to be lost. If disabled, a warning is displayed. This is useful to only use the "navigational" features of the review widget. - Support for node filtering has been added, it can be configured through the filter icon in the title bar. All features listed under Generic Node Filters are supported. If nodes are filtered, all percentages are relative to the filtered set of nodes. 3D viewer: - The color of custom tag spheres can now be adjusted through a "color" button right next to the custom tag pattern. - The color of the floor can now be adjusted though a "color" button next after the "Floor" checkbox. - Skeleton coloring can now be set to not interpolate between different vertex colors and instead use always child colors for an edge. - The color and whether to display mesh faces of individual volumes can now be adjusted more easily. A color selector is available right next to the checkbox of each visible volume in the volume drop-down menu. The global color controls are used as default for newly displayed volumes. - Support for node filtering has been added, which can be configured through the filter icon in the title bar. All features listed under Generic Node Filters are supported. Tracing layer: - When inserting a new node between two existing nodes, the new node's user will now be the logged in user as long as the skeleton is not locked. This makes it easier for reviewers to make corrections, because the new node can now be moved (instead of only initially placed). If the neuron is locked, it is only possible to create a collinear node between parent and child with the child's user (e.g. through tagging a virtual node). Miscellaneous: - When a node is selected a minimal node status line is now shown again using information already available in the client. If the "Show extended status bar information" setting is the Settings Widget is checked, additional information is fetched from the back-end. - The SWC export by default now maps real node IDs to incremental IDs starting with 1 from the root node, which is something some SWC tools expect. To disable this uncheck "Linearize IDs" in the SWC export dialog. - Neuron Navigator: It is now possible to delete multiple neurons from a neuron listing. - The importer widget now allows to allow multiple SWC files at the same time. Bug fixes --------- - Export widget: The SWC export link works again. - Tracing tool: using the personal tag set doesn't remove existing tags anymore when added or removed. - Fix catmaid_insert_example_projects management command. - Review widget: it is possible again to use Q/W to move along already reviewed segments (re-review of nodes). - Fix some accidental key mapping collisions of some special keys and media keys. - Connector nodes can be deleted again right after they were created. - 3D viewer: connector links are displayed again if connector restrictions are in use. - Radius creation works now in orthogonal views as expected. API changes ----------- Additions --------- None. Modifications ------------- - `POST /{project_id}/skeletons/connectivity`: If the new "with_nodes" parameter is true, the involved treenode links are also returned for each partner. Deprecations ------------ None. Removals -------- None. | 17 May 2017, 05:51:29 UTC |
| refs/tags/2017.04.20 | 2017.04.20 | 6447a61 | 2017.04.20 ========== Contributors: Albert Cardona, Tom Kazimiers Notes ----- - A virtualenv update is required. - The location of the `manage.py` script changed: it moved a level up into `django/projects`. All other configuration files remain where they are. Make sure to update your `settings.py` file by replacing the line `from settings_base import *` with `from mysite.settings_base import *`. - Python 3.5 is now experimentally supported. Most functionality should work without problems. To test, make sure to update `settings.py` by replacing the fragment `hashlib.md5(CATMAID_URL)` with 'hashlib.md5(CATMAID_URL.encode('utf-8'))'. - To use the skeleton import API users or groups now need to have the can_import permission. Features and enhancements ------------------------- 3D viewer: - Nodes on specific section of the focused stack can now be automatically moved to an interpolated location. The "Skeleton filters" tab provides now options to either interpolate nodes on broken sections or a custom list of sections. The new location in the average X/Y location of the parent and child. If only parent or child is available (leaf or parent), its X/Y location is used. - An started animation export can now be canceled through a "Cancel" button. Review widget: - Segments can now be reviewed in downstream order by unchecking the "Upstream review" checkbox. Q will still move downstream and W upstream. Already reviewed nodes are skipped in both directions. - Only show "Done" message if 100% are reviewed in one of the selected columns, including Team. Team is now checked by default. Import Export widget: - The Export Widget has been renamed to "Import Export Widget", along with it its short-name for Ctrl+Space. - If a user has import permissions on a project, an "Import" and an "Export" tab are displayed. The new import tab contains a simple SWC import, which allows to select an SWC file and import it. If successful, the new skeleton is selected right away. Neuron Navigator: - Instead of a "Last used" column annotation tables now show an "Annotated on" column. The last used date used before reflected the last change of an annotation itself. Now the creation time of the link relation is displayed, which doesn't change during a merge or split operation, unlike "edition time". Splitting and merging: - In the split and merge dialog, instead of selecting the skeleton/part with more nodes as default "winning" skeleton, the skeleton with a greater cable length is now chosen as default "winning" skeleton. - Keep original creation time and edition time of annotation links that are copied to the newly created part on a split skeleton. - When skeletons are merged and share annotations that should be kept, the older annotation link creation time will now be stored in the final neuron annotation link. Miscellaneous: - Refreshing the nodes on the StackViewer will not print the info on the active node in the status bar. This saves one additional request to the server, speeding up tracing from high-latency locations such as overseas. - The Measurement Table now highlights the active skeleton. - Alt+T can now be used to tag a node with a predefined set of tags. This set can be configured through the Settings Widget, using the "Personal tag set" field in the Tracing section. - The SWC export button in the Tracing Tool toolbar has been replaced with an Export Widget entry. Additionally, SWC files for multiple skeletons can be created at the same time and exported together in a Zip archive. - Many widgets can now have aliases, which will be displayed in parentheses after the name in the window title bar. A small window-like icon next to the window name toggles controls to change the widget alias. - Review status colors can now be more fine-grained. The Settings Widget contains now the option "Use detail review color status" as part of the Tracing section. If enabled, ten different colors plus the regular 0% and 100% color will be used instead of three. - Generating the URL to a view now respects loaded stack groups. If a stack group was initially loaded, it is included in the URL. - It is now possible to control the number of sections moved when Shift is pressed while using ",", "." or the mouse wheel. This step size is controlled through the "Major section step" setting in the "Stack view" section of the settings widget. Alternatively, for a dialog to set a new step size, the key combination Shift + # can be used. - The Connector Table now also displays the link creation time besides the edition time. - Tracing layer: Moving to a child node using "]" doesn't query the server anymore if child info is already available in client. Bug fixes --------- - 3D Viewer: active node sphere is now hidden if no node is selected. - Image data layers that are added to a stack viewer will be added after the last existing image data layer and before other layers. This makes sure tracing data stays on top. - Selecting an unreachable mirror won't hide the tracing layer anymore. API changes ----------- Additions --------- None. Modifications ------------- - `GET /messages/mark_read`: This API took a message ID as parameter before and is replaced by: `POST /messages/{message_id}/mark_read` - `POST /{project_id}/node/user-info`: The `node_id` parameter has been replaced with a `node_ids` parameter, which is expected to be a list of node IDs. The response maps now individual info objects to their respective node IDs. - `GET /{project_id}/connectors/` Each result link now contains one additional column: the link's creation time. It replaces the edition_time in column nine. The edition time is now available in column ten. Deprecations ------------ None. Removals -------- None. | 20 April 2017, 05:53:40 UTC |
| refs/tags/2017.03.16 | 2017.03.16 | 5baf521 | 2017.03.16 ========== Contributors: Albert Cardona, Tom Kazimiers, Andrew Champion Notes ----- - A virtualenv update required! - The 'classic' node provider has been removed, use 'postgis3d' or 'postgis2d' instead. - Performance of the default node query strategy (NODE_PROVIDER = 'postgis3d') improves now when connection pooling is used and PREPARED_STATEMENTS = True. - Both 'postgis2d' and 'postgis3d' node providers support now prepared statements for connector queries. - PyPy is now supported and can be used to improve performance of back-end heavy endpoints. Most functionality is available, except for the following: Ontology clustering, Cropping, Synapse clustering, HDF 5 tiles and User analytics. To use PyPy, a new virtualenv using the PyPy executable has to be created. - There is now a catmaid_prewarm_db management command, which can be used to populate OS and database buffers with heavily used tables. Features and enhancements ------------------------- Graph widget: - The "Selection" tab now has two new buttons that provide the ability to invert the selection, and also to select graph nodes based on matching a text string or by a regular expression (when the text starts with a '/'). 3D Viewer: - With the help of the new "Update active" checkbox in the "View" tab it is now possible to automatically update the active skeleton if it changes. - It is now possible to hide edges that represent a link between a node and a connector. This is also respected with connector restrictions enabled and can be set with new "Show connector links" checkbox in the "View settings" tab. Selection table: - To prevent accidental sorting the new "Lock order" checkbox can be enabled. Clicks on the table headers will have no effect if the order is locked. - Two new action icons are added on the right of each row: move a skeleton up or down in the table. Annotation graph: - A new 'Annotation Graph' widget provides a graph like visualization of CATMAID's annotation space, which is mainly useful to visualize annotation hierarchies. Meta-annotation are linked to annotations through edges. This widget can be opened with Ctrl+Space together with the 'annotation-graph' keyword. - Optionally, the minimum and maximum number of linked annotations in a single hierarchy can be configured. - Selecting an annotation will query all (sub-)annotated skeletons, which can be used as through a regular skeleton source selection in other widgets. Miscellaneous: - Tracing tool: the "Show labels" setting is now remembered across sessions. - Right clicking on a stack viewer won't bring up the browser context menu anymore. Instead, the right mouse button can now be used for panning, too. - The merge dialog has now a "Swap" button in the lower left corner. It can be used to swap winning and losing skeleton in a merge. - Add a 'select' tracing modes to the tracing tool: Clicking an active skeleton or synapse tracing mode button (first two buttons in toolbar) will switch to the select mode where clicking doesn't create new nodes. - The layer settings of image data layers allow now to add custom mirrors, which is useful to e.g. make a local copy of the image data availabl in CATMAID. This can reduce latency due to remote image loading considerably. See the user FAQ in the documentation for more details. - Annotation pages in the Neuron Navigator now also list meta annotations and provide a way to de-annotate them. Bug fixes --------- - Fix occasional tracing overlay resizing problem where a portion of the screen would not show tracing data, but also won't update. - 3D viewer: broken sections can now be displayed again. - 3D viewer: the Z plane with stack images will now render correctly for the default maximum zoom level. API changes ----------- Additions --------- None. Modifications ------------- None. Deprecations ------------ None. Removals -------- None. | 16 March 2017, 05:08:20 UTC |
| refs/tags/2017.02.16 | 2017.02.16 | b74bdcd | 2017.02.16 ========== Contributors: Chris Barnes, Albert Cardona, Andrew Champion, Tom Kazimiers Notes ----- - A new TREENODE_PROVIDER option can be added to settings.py, which can be used to configure the way node queries are executed. Options are 'classic', 'postgis3d' and 'postgis2d'. Depending on your environment, 'postgis2d' might be fastest, but 'postgis3d' is the current default (i.e. what has been used so far). - The new PREPARED_STATEMENTS option can be added to settings.py and set to True to improve node query performance when connection pooling is used. Without connection pooling, this setting hurts performance, which is why it is set to False by default. - Stack mirrors (see below) are not displayed by default in CATMAID's standard data views. To show them, '"show_mirrors": true' (including double quotes) has to be added to the respective data view configuration in CATMAID's admin interface. Features and enhancements ------------------------- Stack mirrors: - To reduce loading time of image data from different places around the world, it is common to copy the image data set and make it available from a server closer to its users. These "stack mirrors" are now handled differently by CATMAID. Until now it was common to select the closest mirror manually by clicking on an image on CATMAID's project list or by clicking on the respective link. To select a particular "stack mirror" one now only links can be used, individual images are not shown anymore. If no images were used before and only links were shown on CATMAID's home page, only small visual change was mode: an extra stack link on top of all mirrors is added. As an alternative to selecting individual mirrors, both, images and stack links can now be used to open a stack as well and CATMAID selects the fastest mirror automatically. - When using links to a particular view in CATMAID ("URL to this view"), CATMAID will automatically select the fastest available stack mirror. - Once a stack is displayed the stack mirror in use can be changed: After clicking on the white-on-blue square in the lower left corner of the image data display, the image display settings will show up. In there the active mirror can be selected from a drop-down list. Treenode Viewer: - A new tool similar to the connector viewer, which allows users to quickly view the nodes in a treenode table. - The viewer is opened from the treenode table. - Nodes are shown only if they are filtered in the table, and appear in the order that they appear in the table. - When the sorting and filtering in the table is changed, users can refresh the viewer from the table to reflect these changes. Connector Viewer enhancements: - Connectors can now be constrained by their pre-synaptic and post-synaptic skeletons. - If either is unpopulated, it is unconstrained on that side (i.e. all outgoing connectors can be found by clearing the 'Post- skeletons' set). - Sorting algorithms based on treenodes associated with the connector (e.g. depth) can be applied either to presynaptic or postsynaptic skeletons. - The 'Reverse' button switches the contents of the two skeleton sets. - The 'Sync' checkbox sets the pre- and post- synaptic sets to have the same contents (the union of their contents when the box is checked) and keeps them that way: this is useful for inspecting all connectors acting within a set of skeletons, such as reciprocal connections. - For undirected connectors (gap junctions, abutting etc.), you can use either the 'pre' or the 'post' set. If both sets are populated, only connectors touching a pre- skeleton and a post- skeleton (with 2 distinct edges) will be shown. - When using the connector viewer as a skeleton source, the output is the union of the two skeleton sets. - The controls have been separated out into tabs. - N.B.: Because the Connector Viewer is now populated in a different way to the Connector Table, you can now only open a Table from a Viewer if one of the skeleton sets is empty, and a connector type other than 'All' is selected. Miscellaneous: - Bookmarks are now persistent for each project. - The Graph Widget now offers two options when exporting SVGs: regular ones and Adobe Illustrator compatible ones (because Adobe isn't SVG standard conform). An option dialog is shown after clicking "Export SVG". - From the Graph Widget exported SVG files preserve now the view of the widget (zoom and pan). - The tag table can now be constrained by a set of skeletons. - The tag table now gives the user information on how many skeletons are being used as constraints, and how many tags/skeletons/nodes are selected. - When the tag table is refreshed, the filters and the last sort are persisted. - The treenode table can now be filtered by node confidence, creator and reviewer. - When creating new volumes with the help of the Volume Manager, the color and opacity of the 3D preview can now be adjusted. Bug fixes --------- - 3D Viewer: custom tag highlighting now also works for tags with upper case letters. - Layer settings: checkboxes now have correct default value. - Tag table: any tags with identical names are now treated as identical. - Tag table: fixed off-by-one error in node count. API changes ----------- Additions --------- None. Modifications ------------- - `POST /{project_id}/node/list` and `POST /{project_id}/node/list`: The returned timestamps are now second based UTC epoch numbers instead of UTC strings. Deprecations ------------ None. Removals -------- None. | 16 February 2017, 07:33:52 UTC |
| refs/tags/2017.01.19 | 2017.01.19 | eec50d6 | 2017.01.19 ========== Contributors: Chris Barnes, Andrew Champion, Tom Kazimiers Notes: ------ - The h5py dependency has been removed. If tile source tile 3 should be used in a new instance, the h5py library has to be installed manually. Features and enhancements ------------------------- Connector Viewer: - A new tool used to view the connectors associated with a skeleton set of skeletons. - Shows a grid of mini stack viewers with their own tracing overlays, focused on connectors associated with the skeleton by a user-selected relation (i.e. outgoing, incoming, gap junction or other). - Connectors can be sorted by their absolute or proportional depth on their respective skeleton trees, by the connector ID or by the skeleton name. - Mini stack viewers can inherit settings from a user-defined main stack viewer; users can focus the main stack viewer on any connector by clicking on its ID in the mini stack viewer title bar. - Users can open a connector table from a connector viewer and vice versa. - Accessible with Ctrl+Space 'connector-viewer'. Connectivity table: - Original colors of skeletons added to a Connectivity Table can now optionally be used when using its skeletons in other widgets (new checkbox: "Original color"). - The colors used in the Connectivity Graph Plot are now the ones assigned to the input skeletons, i.e. the ones selected in the Connectivity Widget. These in turn are either its input skeleton color or the default skeleton color. - Manual re-ordering of partner count columns has been removed. Neurons can now be re re-ordered through the list at the top with the help of two icons in each row (up and down). - All partner tables are now paginated with a default page size of 50 entries. The page size can be adjusted for all tables at the same time with a drop-down menu at the top. "Select all" check-boxes select all entries across all pages. Graph widget: - Active Graph Widget windows will now zoom in smaller steps if the Shift key is pressed. - Graphs saved to a JSON file now keep visibility information. Loading them will load all nodes hidden that have been hidden when saving the file initially.. 3D Viewer - Meshes are replaced with volumes and the "Show meshes" checkbox has been removed. Existing meshes have been transformed into volumes. - The new coloring mode "Last Reviewer" will color skeleton nodes by the user color of the user that reviewed them last. The "User colormap" button can be used to show the mapping from color to user name. Miscellaneous: - The Selection Table can now be opened through Ctrl+Space by using the handle 'selection-table' instead of 'neuron-staging-area'. - Project and stack menu entries are now sorted by default, which makes it easier to deal with many projects and stacks. - Node bookmarks can now be removed through an X icon in their respective row in the bookmark dialog. - Skeleton Analytics in the Review Widget will now identify nodes in broken sections of all stacks linked to the current project. - The front page project list can now be loaded as a widget using Ctrl-Space with 'project-list'. - Synaptic fractions: colors of groups and partners can now be changed through legend of graph. - The tag table now has a refresh button to manually update the cache and redraw the table. - The tag table can now open a treenode table pre-filtered for nodes with the selected labels. Bug fixes --------- - The size of the embedded 3D viewer in the split/merge dialog is now adjusted dynamically based on the available space. This prevents some problems with lower display resolutions. - 3D viewer: loading of box volumes workes again. - The statistics widget back-end will now correctly use up-to-date time-zone information for the query time range. This fixes some time zone conversion corner cases. - Graph widget: SVG export works again. The exported SVG now groups labels with node/edge. Now also single node exports are supported. - If Ctrl-Z was pressed and released very quickly, two undo steps were taken. Now always only one undo step will be done per single Ctrl-Z click if not hold down. - 3D viewer: partner node spheres are now also shown for restricted connectors. - Multiple stack viewers no longer use the same ID to make requests to the database. - The connector table can now be used as a skeleton source, where previously an error would be raised. - The tag table now collapses any tags with identical names, but as a consequence does not show the tag ID (as there may be multiple IDs) API changes ----------- Additions --------- - POST `/{project_id}/analytics/broken-section-nodes`: Get s list of all nodes that are currently located in a broken section of any stack linked to their project. Obtionally, specific skeletons can be checked. Modifications ------------- - `POST /{project_id}/skeleton/analytics` Is renamed to `POST /{project_id}/analytics/skeletons`. Deprecations ------------ None. Removals -------- - `GET /{project_id}/stack/{stack_id}/models` Meshes have been replaced with volumes. | 19 January 2017, 06:37:26 UTC |
| refs/tags/2016.12.16 | 2016.12.16 | ee8c8a1 | 2016.12.16 ========== Contributors: Chris Barnes, Andrew Champion, Tom Kazimiers Notes ----- - Virtual env update required - Postgres 9.6 is now supported. Features and enhancements ------------------------- 3D Viewer: - Shift+Click can now be used to jump to arbitrary locations on rendered skeletons. Objects already clickable in the past (like tags or the soma spheres) are still given precedence. Tag Table: - New widget allowing users to get information about node label usage in the project, and select skeletons based on labels which their nodes have. - Accessible with Ctrl+Space by the name 'tag-table' or through the 'T' widget button in the Tracing Tool. Measurement Table: - The neuron name is now quoted in the CSV file export. This makes it more robust when commas are used in the name representation (e.g. if annotations). - XLSX spreadsheet export is now supported through an "Export XLSX" button. Importer: - Add support for importing ontology and classification information along with projects, stacks and stack groups in project file based import ("Image data importer" in admin view). - Projects to be imported can be split across multiple documents, if local or remote file import is used. This helps organizing image collections manually. Tracing tool: - Holding P will show the active skeleton in all open 3D viewers. - The semicolon (";") key no longer switches to skeleton tracing mode, because it is active by default. - Bookmarks can be set by pressing semicolon (";") and then a marker key, which will mark the active node (or location if no node is active) with that key. Pressing backtick ("`") followed by the marker key will return to the marked node or location. Pressing single quote ("'") followed by the marker key will instead activate the marked skeleton and move to the closest skeleton node. - Shift + H will go to the last node you edited in any skeleton. Tracing layer: - Connectors connected to the active skeleton are now colored with a distinct, more yellow hue of orange, even if the connection is not in the visible section. Miscellaneous: - The Graph Widget can handle larger graphs much better now. Also its mouse action have slightly changed: moving while having the left mouse button down will pan the view, pressing additionally the Ctrl key enters rectangular selection mode. Deprecations and Removals ------------------------- - Special behavior of tile source type 2 stacks to interoperate with a Volumina tile server prototype has been removed. Bug fixes --------- - Review widget: auto centering works again - Review widget: location lookup of warnings now works again in all cases. - Skeleton source subscriptions: fix accidental sharing of skeleton sources. This caused e.g. losing the connection between a Selection Table and a 3D viewer as soon as another 3D viewer was opened. - The Classification Editor of CATMAID's Ontology Tool can be started again. - Using the closing bracket ("]") to walk a neuron does not stop working anymore after the end of a branch is reached. - 3D viewer: finding the date of the most recent change among all skeletons considered in a history animation now works as expected. The end point of the animation is now calculated correctly and all changes can be seen. - The Classification Clustering Widget can be opened again. API changes ----------- Additions --------- - `GET /{project_id}/labels/stats` Get statistics on node label usage for the project. - `POST /{project_id}/skeletons/node-labels` Return mappings from node label IDs to IDs of skeletons which include a node with that label. Modifications ------------- None. Deprecations ------------ None. Removals -------- None. | 16 December 2016, 06:42:46 UTC |
| refs/tags/2016.11.04 | 2016.11.04 | 9061b6e | 2016.11.04 ========== Contributors: Gregory Jefferis, Tom Kazimiers Notes ----- - Virtualenv update required Features and enhancements ------------------------- Tracing layer: - Alt+Click so far created gap junction connectors. This behavior is replaced with opening a small context menu that provides access to all currently available connector types (abutting, gap junction, presynaptic, postsynaptic). Optionally, through the Settings Widget, remembering the last connector type created can be enabled. If this is the case, regular Shift+Click behavior is to create the last connector type, as opposed to pre/post-synaptic connectors. 3D viewer: - History replay now has a reset button to load the most recent version of each skeleton. The new pause button will stop the animation at the current time and pressing start will resume playback. Additionally, a slider control now allows to move to arbitrary points in time of the history animations. Touching the slider will automatically pause the replay. Neuron dendrogram: - Controls are now organized in tabs and a new setting was added to change the line width. Miscellaneous: - If users have sufficient permissions, they can click on individual names in the Project Statistics Widget to show a User Analytics window for the respective user and currently selected time frame. - Pressing Ctrl+Space will now open a dialog which allows opening a widget based on its short name (e.g. neuron-dendrogram) or parts of it. - A small system check widget has been added, mainly useful for development. It currently only supports FPS measurement and can be opened by pressing F6 and entering "system-check". Bug fixes --------- API changes ----------- Additions --------- - `GET /{project_id}/skeletons/{skeleton_id}/compact-detail` Provides same functionality as `GET/POST /{project_id}/{skeleton_id}/[0|1]/[0|1]/compact-skeleton`, but uses explicit GET parameters. - `POST /{project_id}/nodes/` Provides the same data as the former `POST /{project_id}/nodes/list` and takes the same parameters. Modifications ------------- None. Deprecations ------------ - `GET/POST /{project_id}/{skeleton_id}/[0|1]/[0|1]/compact-skeleton` This endpoint will be replaced in the future with the newly introduced endpoint `GET /{project_id}/skeletons/{skeleton_id}/compact-detail`. - `POST /{project_id}/node/list` This endpoint will be replaced in the future with the newly introduced endpoint `POST /{project_id}/nodes/`. It takes the same parameters. Removals -------- None. | 04 November 2016, 06:37:47 UTC |
| refs/tags/2016.10.18 | 2016.10.18 | cdea705 | 2016.10.18 ========== Contributors: Andrew Champion, Tom Kazimiers Features and enhancements ------------------------- 3D viewer: - Picking now respects the Z plane. if displayed. Shift+click any location on it and the stack viewer position is changed accordingly. This works just like picking nodes, except that the active node doesn't change. - The original camera location is now restored by default after exporting an animation. - A new tab called 'History' gives access to tools for replaying the reconstruction of the currently loaded skeletons. The time range as well as the time advance per frame can be adjusted. By default, the time range covered starts ith the first change and ends with the last one (when no custom date is entered). Optionally, empty bouts where no changes happend will be skipped if a length (in minutes) is specified. If not disabled through the 'Include merges' checkbox, arbors that only where merged in at one point will also be displayed before such a merge. Tags on individual nodes are currently hidden during animation. Review widget: - Skeleton Analytics, which was a separate widget before, is now available through a new tab in the Review Widget. It still lists the same problems for selected neurons as before (i.e. missing end tags). Connector table (available through Neuron Navigator): - Support for abutting connectors and gap junctions has been added. - The displayed table can now be exported as CSV file. - The listed information for connector relations with only one partner is now consistent with multi-relation cases: the linked node ID, node location and skeleton ID are shown instead of the connector location along an empty node and skeleton fields. - The widget can now pull skeletons to list connectors for from other skeleton sources. It acts itself as a skeleton source as well and provides all result skeleton IDs. Importer: - The project and stack importer now supports the customization of when projects are considered known as well as what to do with known projects: ignore, merge or replace. - If remote hosts are used as a project or stack import source, HTTP Authentication can now be used to get access to a server. Miscellaneous: - The tracing tool has a new icon. - If users get a permission denied error (e.g. due to being logged out or just having not enough permissions), a login dialog is now shown. It allows users to re-login or change the user entirely. The action causing the permission error, is *not* repeated automatically. - Using brackets to navigate along a skeleton now also works if the reconstruction data is hidden (e.g. when the space bar is held down). Bug fixes --------- - The statistics widget now properly respects time zones when grouping by day. - Partner neurons listed in the Connectivity Widget can now be filtered again with regular expressions (when the filter pattern starts with "/"). - Loading stack groups through URLs now correctly respects the specified location. - H works correctly when a virtual node is active. - Pressing E in the Review widget now works again when a segment was completely reviewed. - The group membership permission tool in CATMAID's admin area works with groups again. API changes ----------- Additions --------- - `GET /{project_id}/connectors/` Replaces the `POST /{project_id}/connector/table/list` endpoint, but also changes the parameter names. Additionally, the "relation_type" parameter is now expected to contain the actual relation name instead of a numeric alias: The value "0" is replaced with "postsynaptic_to" and "1" is replaced with "presynaptic_to". See /apis documentation for details. Modifications ------------- None. - `GET/POST /{project_id}/[0|1]/[0|1]/compact-skeleton` The new parameter with_history allows to include historic data in th response. Will also include timestamps for regular nodes. Deprecations ------------ None. Removals -------- - `POST /{project_id}/connector/table/list` This endpoint is replaced by the `GET /{project_id}/connectors` endpoint, described above. | 18 October 2016, 04:04:17 UTC |
| refs/tags/2016.09.01 | 2016.09.01 | 5ed4d56 | 2016.09.01 ========== Contributors: Andrew Champion, Tom Kazimiers Features and enhancements ------------------------- 3D viewer: - The 'View settings' has a new option: 'Use native resolution'. When activated (default), the native resolution of the current display will be used. This improves image quality on HiDPI displays like Apple Retina. If the performance penality is too big for large scenes, this can be switched off again. Connectivity Matrix: - With the help of the "Export XLSX" button, the currently displayed matrix can be exported as a Microsoft Excel compatible XLSX file. Colors are preserved. Miscellaneous: - With the help of the 'sg' and 'sgs' deep link parameters, stack groups can now be loaded directly through a URL. Bug fixes --------- - If multiple stack viewers are open, skeletons can now me modified again across all open tracing layers. E.g. with orthogonal views, selecting a node in one view and adding a child in another view work again. API changes ----------- Additions --------- None. Modifications ------------- None. Deprecations ------------ None. Removals -------- None. | 02 September 2016, 03:12:16 UTC |
| refs/tags/2016.08.26 | 2016.08.26 | 3e44f01 | 2016.08.26 ========== Contributors: Andrew Champion, Tom Kazimiers Features and enhancements ------------------------- 3D viewer: - When coloring by creator the user colormap dialog only shows users who have created at least one node loaded in the view. Additionally, a new coloring mode, "By Creator (relevant users)", will generate a new set of colors for these users from the CATMAID color scheme. This is useful if many users have similar colors in their user profiles. - Rendering and removal of skeletons is much faster, which is especially noticeable for > 100 loaded skeletons. This also enables the use of a more accurate node picking (Shift+click) algorithm as default, which before was only used as fallback. Volume manager: - Volumes an now be removed (given a user has the required permissions) by clicking on the 'remove' link in the last column of the volume table. Statistics widget: - If a user has the can_administer permission for a project, the Statistics widget now displays an extra button to open the new User Analytics widget. It displays the same information as the admin view with the same name. The user analytics view now offers also options to adjust the max. inactivity time and whether all write operations should be included (as opposed to only node and review changes). Tracing overlay: - Radii can now be set to be visible for no nodes, the active node, all nodes in the active skeleton, or all nodes through the Settings Widget. - Pressing Ctrl + O will set a radius with the measurement tool without bringing up the confirmation dialog. Miscellaneous: - Holding Ctrl with < or > will now smoothly animate through sections as fast as the active layers will allow. This also works with Shift to move 10 sections at a time. - The log now displays times in the local timezone. - The connector table now lists the confidence of both the link to the connector and from the connector to the target treenode. Bug fixes --------- - Remove major cause of CATMAID freezing after the display of an error message. - Annotation search lists all results again, not only first page. - When joining skeletons, the creation time of annotations is preserved. - Fixed an error preventing branching from virtual nodes in some cases. - The history widget correctly displays the action time, not the current time. API changes ----------- Additions --------- None. Modifications ------------- None. Deprecations ------------ None. Removals -------- - `GET /{project_id}/stats` This endpoint returned an HTML document displayed by CATMAIDs statistics widget. | 26 August 2016, 06:00:54 UTC |
| refs/tags/2016.08.12 | 2016.08.12 | c03bf35 | 2016.08.12 ========== Contributors: Andrew Champion, Tom Kazimiers Notes ----- - Release 2016.08.09 is deprecated. If you have it installed, please upgrade to this version, 2016.08.12. Features and enhancements ------------------------- Tracing overlay: - Node tags now respect visibility groups. 3D viewer: - Exporting an animation will now use the rotation axis selected in the regular widget controls. Bug fixes --------- - The browser link preview no longer obscures the status bar when hovering over the tracing layer. - Node tags are correctly hidden when holding Space. - Fixed an error that could sometimes happen on page load for anonymous users. - Missing documentation for curent volumes features added to API changes ----------- Additions --------- None. Modifications ------------- None. Deprecations ------------ None. Removals -------- None. | 12 August 2016, 05:10:48 UTC |
| refs/tags/2016.08.09 | 2016.08.09 | b47e2f6 | 2016.08.09 ========== Contributors: Albert Cardona, Andrew Champion, Tom Kazimiers Notes ----- - A virtualenv upgrade is required. - PostgreSQL 9.5 and PostGIS 2.2 is now required. When updating, update PostGIS first and update all databases in which the PostGIS extension is installed by running "ALTER EXTENSION postgis UPDATE;". Then perform the Postgres update. Features and enhancements ------------------------- Tracing overlay: - Visibility groups can be defined that hide or show nodes in the overlay based upon filtering criteria such as neuron meta-annotations or node creator. Unlike the skeleton source based visibility, visibility groups can be toggled instantly with HOME (for group 1) or Shift + HOME (for group 2). For meta-annotation based visibility, this does not require using a search as a skeleton source, and the set of skeletons matched by the meta-annotations is transparently refreshed in the background. Another visibility group, "Always visible", establishes a set of filters for overriding hidden groups such that skeletons matched by these filters will always be shown. - The active node color for virtual nodes can now be configured to be different than for read nodes. - The active node color for suppressed virtual nodes can be configured to be different than for unsuppressed virtual nodes. Note this only takes effect if the "Respect suppressed virtual nodes during navigation" setting is enabled. 3D viewer: - Through the "List connectors" button on the Main tab, it is now possible to open a connector selection with all currently loaded connectors in it. Skeleton visibility and connector restrictions are respected. Importer: - Projects and stacks available on remote servers can now be imported, optionally with API-key authentication on other CATMAID instances. The remote data source can of course be any URL in a JSON or YAML format understood by CATMAID. The import section in the CATMAID documentation holds more detail on this. For CATMAID, the new "projects/export" endpoint provides all required data that is visible to the requesting user. Graph widget: - The new button "Open Connectivity Matrix" in the Export tab will open a new Connectivity Matrix widget for the current graph, including its groups. Connectivity matrix: - It is now possible to manually change the order of multiple entries at once, which is useful to move sets of entries. The "Display" tab now has a "Manually edit order" option. If checked, number input boxes are shown next to each row and column head as well as a "Re-order" button in the top-left cell if the table. After the numbers are adjusted to the desired order, the "Re-order" button will apply the new ordering. Negative and decimal numbers can be used. - Connectivity matrices can now be exported as PDF. The "Export PDF" button on the "Main" tab will open a dialog explaining that this PDF export is made through having the browser print the table and how to enable colors. Pressing "Print" will show the browser's print dialog for only the table. Settings widget: - Tracing overlay colors customized in the settings widget are now persistent. - Neuron name settings customized in the settings widget are now persistent. - The delimiter used to separate annotations in a neuron name can now be configured in the Annotations section of the Settings Widget. - It is now possible to configure the available page length options used by most tables from a central place. This is done through the "Table page length options" setting, which is available from the Settings widget. For widgets to be aware of page length setting changes, they have to be reloaded. History tables: - Starting with this release, CATMAID will record every single change to its database tables in so called history tables. This makes it possible to reconstruct the actual history of data (e.g. neurons) and user contributions. Even data deleted in CATMAID can now be recovered without touching backups. - The log widget in the front-end provides a way to few the history: It has a new tab called "History", where each event that caused related database changes is listed. Miscellaneous: - Alt + Y will always create a new selection table and add the active neuron to it. Also works with Shift. - Images on CATMAID's front-page are now loaded lazily, i.e. they are only requested and shown once they come into view. This improves performance significantly when displaying many sample images. - New filter "Label Color Map" will false-color stacks of label ID images. - The button "Add annotations to neurons" above annotation lists in the Neuron Navigator makes it possible to send currently selected annotations to other neurons. Those target neurons are selected by choosing a skeleton source in a dialog box, which is shown to the user once the button is pressed. Bug fixes --------- - Additive blending between layers now works also when filters are in use. This allows for proper in-browser composite generation. - Hidden nodes are no longer selected by G or Shift + Y. - All skeleton sources are now selectable when exporting NeuroML. - Fix "Reset to inherited default" and "Lock this setting" buttons in settings controls not being clickable. - All layouts of the color picker can be used again (i.e. resizing it). API changes ----------- Additions --------- - `GET projects/export`: Provides all available information on the structure and properties of projects and stacks. Supports application/json and application/yaml content types. A return YAML document matches the format supported by the importer. - `POST /{project_id}/connector/info`: This endpoint replaces the `/{project_id}/connector/pre-post-infos` endpoint. The `pre` and `post` parameters are now optional. - `POST /{project_id}/neurons/from-models`: Get the IDs of all neurons modeled by a list of entities, e.g. skelton IDs. - `POST /{project_id}/skeletons/import`: Import a neuron modeled by a skeleton from an uploaded file. Currently only SWC representation is supported. - `GET /{project_id}}/transactions/` Get a list of transaction objects, ordered by time (latest first). A sub-range can be specified optionally. - `GET /{project_id}}/transactions/location` Get a location representing the change in a given transaction. Returns error if no location was found. Modifications ------------- - `GET /projects/`: Does not include the catalogueable property of projects anymore. Use ontology queries to filter by the "driver_line" class for the same semantics. - `POST /{project_id}/annotations/forskeletons`: Parameter `skeleton_ids` now correctly parses with and without explicit indices. - `POST /{project_id}/annotations/query`: Parameter `object_ids` now correctly parses with and without explicit indices. - `POST /{project_id}/annotations/query-targets`: Parameter `types` now correctly parses with and without explicit indices. Deprecations ------------ None. Removals -------- - `POST /{project_id}/connector/pre-post-info`: This endpoint was renamed to `/{project_id}/connector/info` endpoint. | 09 August 2016, 05:10:03 UTC |
| refs/tags/2016.05.26 | 2016.05.26 | 36649f2 | 2016.05.26 ========== Contributors:: Albert Cardona, Andrew Champion, Tom Kazimiers Notes ----- - The default image base setting for the importer has changed. If you use the importer along with this setting, please update your settings.py file to now use IMPORTER_DEFAULT_IMAGE_BASE instead of CATMAID_IMPORT_URL. The semantics stay the same. Features and enhancements ------------------------- Graph widget: - If a skeleton is appended that already exists in a group, the group's color and label now doesn't change anymore. Instead a info message is shown. - Selected edges can now be removed with the help of the "Remove" button in the "Selection" tab. Also, a help text icon has been added to the title bar. The widget help window currently only contains information on how edges/links between nodes can be hidden. Volume widget: - Preview for alpha shapes is now disabled by default due to its potential re-computation cost. - Convex hull and alpha shape meshes are now only automatically re-generated on property changes if preview is enabled. - Saving a new volume makes sure the volume's mesh is up-to-date and will re-generate it if needed. Re-generations will now also show an info dialog. If no mesh could be generated, saving is not allowed and the edit form will stay open. - Two new filters for convex hulls and alpha shapes are now available: "only end nodes" (optionally including the root) and "only branch nodes". These will restrict the base point set for volume generation. - Alpha shapes now use the inverse of the alpha value used so far. This makes it easier to use since it translates directly into nanometers. - If a synaptic connection filter is used with Alpha shapes and convex hulls, it is now possible to select all synaptic nodes, regardless of the partner skeleton (select "None" as partner neurons), and to select both pre- and post-synaptic nodes at the same time. - Alpha shapes now use a different implementation which takes a little bit more time to compute, but doesn't require re-computation if different alpha values are used. This makes finding a good alpha value much quicker. The input field for the alpha value to use is now also a numeric field in which arrow keys and mouse wheel can be used to change the value. A second numeric input allows to change the step size of alpha value changes. - For preview, volumes now use the color and opacity defined in the 3D viewer. Tile layer: - An efficient browsing mode is now available that will not load tiles at the periphery of the stack viewer. This is useful to reduce data use and browsing latency on bandwidth-limited connections. To use this mode, increase the "Tile area efficiency threshold" in the tile layer controls. 3D viewer: - Meshes and volumes can now optionally be displayed with visible faces instead of wireframe only. - Volume list is now updated when new volumes are added, re-opening the widget is not required anymore. - Transparent volumes are now displayed correctly. Miscellaneous: - If a client tries to perform an operation without having the most recent data available and the performed action is canceled, a more helpful dialog is now shown. It explains the situation and offers to refresh the client view (currently only nodes in the tracing layer are refreshed). Administration: - The image data importer available from CATMAID's admin interface supports now the specification of stack groups. It can also apply custom translations when mapping imported stacks to imported projects. Bug fixes --------- - Creating nodes using the Z key without other nodes in close proximity works again. - Zoom level slider initialized correctly for stacks with eight zoom levels. - Showing connector info for edge in Graph widget (Alt+Click) now works also if the source is a single neuron and the target a group or split node. - Activate target node of a joined-in skeleton again. API changes ----------- Additions --------- None. Modifications ------------- None. Deprecations ------------ None. Removals -------- None. | 26 May 2016, 19:54:00 UTC |

This is now the default and can be changed in the settings widget with the help of the "Use source colors" checkbox. - Unavailable images on CATMAID's front pages are now displayed as a gray placeholder box, instead of the broken image icon of the browser. - A new volume type was added: alpha shapes can now be created in practically the same way as convex hull volumes are created. Alpha shapes have one additional parameter: alpha. It is used to filter edges for result mesh and has to be fairly low with our spatial dimensions. Values around 0.00001 seemed to work well in some cases. The preview of alpha shapes is disabled by default, because they can take much longer to compute. - Materialized virtual nodes have now the correct edition time set, which make operations like adding a child to a virtual node work again (state checks prevent this with wrong edition time). - The neuron search will now show a warning and cancel a search if a query annotation doesn't exist and the query term doesn't start with a forward slash (used for regular expressions). Bug fixes --------- - Creating synaptic connections from connector nodes across sections works again. - Inserting a node along an edge will now render correctly right after using ctrl+alt+click. - Merging two skeletons while the losing skeleton was loaded into another widget (e.g. Selection Table) doesn't trigger an error anymore. - Undoing confidence changes works again. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJXFF6hAAoJEAganiFb3SCDkvoP/2NbUTRPECIFU0dRTSzbocl4 tS7C6ofS0Ma92x5e4y9SntvFfa7LKvivkyZLd2+HE4zqr2YGGaOSUEYuIyK0Rgwt tQ4QIhp9cXuL2pzKHW3dqeyoe2C61bYo0wEPYgX9siaEpLSEAsf5AtV5zn4ZQE6q l8rFF0DecRqHdLC8xanZZrBc6/CS74nsDQmbLTeuCabF9u0IFiw+MD+TWjNDjUio VRsl65QHFsPDVXgCFnZHKVIyCbPCrdA28WcT5QNevqAspXMfGrIvsQ6K+EqGVN+U Rf5D0mupnpwJ8KL2ByGDCprm+L1BHk8+fkZeULpgVzVThc2BInh7HhPf2PpBu25S D8VlfhXCrZljqWdjCmIaH3BjwDfXQIJECstOAwqUbUpKJNv9bdgp4sNwREfE9a1T w+m6sRFP1cY4en6/QLjR+X1RoxTj4KqKVDEiCaZGoOoF6W9843ih5maBQOfUvDMR eQ32BVlfhXx0VdHIIJmgR+8fcyazOFPukjMpCxMkkBNfc6UmcqYRPHrdWy8oS4+b 0axI43jF9OAjgFgL+FcCGeCVx9pPJEX+M0zYWqxe0F2CpCNadbISFiKSwFlS5fab QLat7FxWMUH/kA/UlySbmzyQTk9Kix9LmUlBQS6yJNzDh4vD4lxKMH5V8lHYgic3 0q9OpTj1GKW3biY8Mgqr =j5bU -----END PGP SIGNATURE----- | 18 April 2016, 04:11:36 UTC |
| refs/tags/2016.04.15 | 2016.04.15 | b0a5e3d | 2016.04.15 ========== Contributors: Albert Cardona, Andrew Champion, Daniel Witvliet, Stephan Gerhard, Tom Kazimiers Notes ----- Starting with this release CATMAID uses a new database migration system. To update an existing CATMAID instance safely, please follow these steps: 1. Make sure you have CATMAID updated to the last release (2015.12.21), including all database migrations and up-to-date Python packages. 2. Upgrade to this version (or a newer one) and update pip and all Python packages (in within your virtualenv), South can be removed afterwards: pip install -U pip pip install -r requirements.txt pip uninstall south 3. Fake initial migrations (and only the initial migrations!) of all used Django applications to register current database state: python manage.py migrate admin 0001_initial --fake python manage.py migrate auth 0001_initial --fake python manage.py migrate authtoken 0001_initial --fake python manage.py migrate catmaid 0001_initial --fake python manage.py migrate contenttypes 0001_initial --fake python manage.py migrate djcelery 0001_initial --fake python manage.py migrate guardian 0001_initial --fake python manage.py migrate kombu_transport_django 0001_initial --fake python manage.py migrate performancetests 0001_initial --fake python manage.py migrate sessions 0001_initial --fake python manage.py migrate sites 0001_initial --fake python manage.py migrate taggit 0001_initial --fake 4. In the future no syncdb step is required anymore. Continue with the rest of the regular update procedure: python manage.py migrate python manage.py collectstatic [-l] This procedure will only be required for upgrading an existing instance to a release newer than 2015.12.21. It won't be needed to migrate from newer releases. Also note that if you are running an Apache/mod_wsgi setup (or referencing django.wsgi), you have to re-generate your configuration with: ./django/create_configuration The following variables have to be removed from settings.py files: TEMPLATE_DIRS, TEMPLATE_DEBUG Additionally, PostgreSQL is now required to be of version 9.4. Features and enhancements ------------------------- Tracing overlay: - Colors of skeleton nodes and edges in the tracing overlay can now be configured to follow colors from selection tables. To configure which skeleton sources to use to select colors, click the skeleton source control icon (the gear) in the title bar of the stack viewer. - Visibility of skeletons in the tracing overlay can also be controlled by skeleton source subscriptions. To enable this, check "Hide skeletons not in the skeleton source subscriptions" in the Settings widget under Tracing Overlay > Skeleton colors. Note that it the tracing overlay may not update the visibility of some skeletons until a navigation action is performed. Gap junctions: - A new non-directional connector type for gap junctions can now be created when tracing by Alt + clicking in the tracing overlay. Edges for gap junctions are displayed in purple. - Gap junction partners can optionally be displayed in a separate table in the Connectivity Widget by checking "Show gap junctions". This table has its own selections for confidence and count thresholds. Volumes: - The volume widget can create a new volume type: convex hulls. These can be created around a set of nodes from any skeleton source. Different filters can be combined: filters to allow only nodes that have a certain tag, a sub-arbor relative to such nodes (optionally occurring a definable number of times), a region between two tags tag or nodes that are synaptic to skeletons of another skeleton source. Node radii can optionally be ignored, but they are respected by default. A preview of the current filter set can be displayed in the first available 3D viewer. 3D Viewer: - Gap junctions are displayed like synapse edges in purple. - Stack related settings (bounding box, missing sections and z planes) are now moved to a tab called "Stacks". - Stack bounding boxes and missing sections now update when stack viewer focus changes. - A new sphere shading allows for a better depth perception. - Volumes (created in the Volume Widget) can be displayed. A new selection control in the "View settings" tab allows to select individual volumes. They are colored the same way as they regular mesh. Currently, the color isn't updated on purpose to allow the easy creation of differently colored volumes. - When the current Z plane is displayed, it will now have the section's images data mapped to it. The used zoom level (resolution) and the opacity can be adjusted and orthogonal stacks are supported, too. - When restricting connectors to those shared by groups, you can now choose to include only those linking pre->post between the two groups in a specific direction. Skeleton Projection layer: - Instead of supporting only the display of the active skeleton, the projection layer can now subscribe to other skeleton sources and display multiple skeleton projections at the same time. The used source can be selected in the Settings Widget. This way, for instance, a Selection Table could provide input to the projection layer and effectively control which skeletons will be projected. And Through its own subscriptions, the Selection Table could even provide a dynamic list that includes the active node. Neuron Search: - A search result can now be exported as CSV. Only selected rows are exported. The resulting CSV will contain neuron IDs and neuron names. If annotations are displayed, a third column includes annotations. Undo: - Some actions are now stored as so called commands in a history, which can be displayed in a dialog by pressing the F9 key. Commands in this history can are reversible. They can be undone either through the history dialog or by pressing Ctrl+Z. - Through the history dialog, undone commands can also be redone. Of course, once one diverges from the list of previously undone commands by executing a completely new command (e.g. creating a node), redo is not possible anymore. - The following actions are recorded into history: tag add/remove/edit, annotation add/remove/edit, node radius edit, neuron rename, confidence change, connector link/unlink and node add/insert/move/remove/. Ontologies, classification and clustering: - Ontology tool widgets don't reset each other anymore if they are loaded. - The Classification Editor and Ontology Editor open sub-trees now quicker. - Clustering ontology based classifications is much faster and works for multi-level ontologies on thousands of classification graphs. Administration and Performance: - The return type of many performance-critical queries, like querying nodes for the tracing overlay, is now correctly specified as 'application/json' rather than 'text/html'. Make sure your nginx has gzip enabled for the 'application/json' type in its 'gzip_types' setting so that these responses are compressed. Miscellaneous: - Dragging a window into the center of another window now creates a tabbed window where both windows share the same area of the screen and can be switched between using tabs at the top of the window. Additional tabs can be added by dragging more windows into the center of the tabbed window. The active tab can be removed from the tabbed window by dragging it to another location in the window layout. - Dragging a window onto the top, left, bottom, or right edge of an already tabbed window while holding SHIFT will add it to that location inside the tab. - There is now a setting to invert the behavior of CTRL when navigating parent/child topology, i.e., when enabled [ and ] will navigate to the next real node by default, while holding CTRL will go to virtual nodes. - Which layers are hidden when Space is held is now configurable by checkboxes in the Stack Viewer's layer controls. - Scroll bar positions in widgets are now maintained when they change their size. - Non-superusers can now see user analytics and proficiency reports for projects for which they are administrators. - WebGL layers are now compatible with DVID stacks. - Tile layers now have an option in the layer controls to hide the tile layer if the nearest section is marked as broken, rather than the default behavior of displaying the nearest non-broken section. - Clustering over large sets of ontology based classification is now much faster. Bug fixes --------- - The skeleton projection layer can be used again and now renders lines with the same width as the tracing layer. This width can be configured in the settings widget. - Color pickers will now update the color of color picker enabled DOM elements again. - Fixed hiding edges with less than 2 synapses in the Graph Widget resulting in no edges. - Fixed an issue where cloning the Graph Widget cloned into the wrong widget. - Fixed an issue preventing removing split neurons from the Graph Widget. - Fixed an intermittent exception when renaming neurons. - Fixed a second Neuron Search widget not working properly. - Adding a neuron to a Selection Table now re-runs the sorting scheme. - Fixed Connectivity Matrix cloning. API changes ----------- Additions: - `GET /{project_id}/labels/[treenode|connector]/{label_id}/`: Returns a list of labels for a node. - `GET /{project_id}/connectors/{connector_id}/`: Returns information on a connector and its partners. - `POST /{project_id}/skeletons/within-spatial-distance`: Find skeletons within a given L-infinity distance of a treenode. Modifications: `POST /{project_id}/skeletons/connectivity`: - Response object now includes `gapjunctions` and `gapjunctions_reviewers` properties for gap junction connectors. - Documentation has correct parameter name: `source_skeleton_ids` not `source`. `POST /{project_id}/label/[treenode|connector]/{label_id}/update`: - Returns now also information about what labels were added, which were duplicates and which labels were deleted. `POST /{project_id}/label/[treenode|connector]/{label_id}/remove`: - Returns now also information about which label label was eventually removed. If nothing went wrong the field deleted_link has the input label ID. `POST /{project_id}/annotations/remove`: - The return field `deleted_annotations` is now called `deleted_links` and continues to contain a list of class_instance_class_instance IDs that were removed. The new `deleted_annotations` field contains a mapping of removed annotation IDs to the IDs of the object they were removed from. `POST /{project_id}/connector/delete`: - The response contains now detailed information about the removed connector, including its partners. `POST /{project_id}/node/list`: - Edition times of nodes and connectors-links are now returned, too. Therefore some array indices changed. - Link and connector types are now returned in a more general fashion. Instead of providing four different arrays for pre, post, gap-junction and other connectors (previously index 5, 6, 7, 8), each connector entry now contains one list with all links (index 5), each link is represented as [<treenode_id>, <relation_id>, <link_confidence>]. `POST /{project_id}/treenode/delete`: - A list of removed links is now returned as well. Each entry has the following format: [<link-id>, <relation-id>, <connector-id>, <confidecen>]. `POST /{project_id}/treenodes/{treenode_id}/confidence`: - Edition times of nodes and connectors-links are now returned, too. Each location ID in the returned updated_partners object, is now mapped to an object with an "edition_time" and an "old_confidence" field. - An optional "partner_ids" parameter is now accepted. If the "to_connectors" parameter is set to true, the "partner_ids" parameter allows to update only the links to the provided connector IDs. - An optional "partner_confidences" parameter is now accepted. If the "partner_ids" parameter is used, the "partner_confidences" parameter allows to specify an individual confidence for each selected partner. `POST /{project_id}/skeleton/join`: - IDs of the result skeleton and the deleted skeleton are now returned. Deprecations: None. Removals: -`[POST|GET] /{project_id}/label-for-node/[treenode|connector]/{label_id}`: Has been replaced with: `GET /{project_id}/labels/[treenode|connector]/{label_id}/` | 15 April 2016, 14:36:40 UTC |
| refs/tags/2015.9.11 | 2015.9.11 | 5345229 | 2015.9.11 Contributors: Albert Cardona, Andrew Champion, Tom Kazimiers Features and enhancements ------------------------- Neuron Navigator: - It is now possible to remove multiple annotations at once from a neuron. A new column is added to annotation tables, each annotation row has now a checkbox in its first column. A click on the de-annotate link in this column's header or footer will remove all selected annotations from the current neuron. Tracing: - If a single-node skeleton is merged into another skeleton, no merge dialog is now shown by default. All annotations of this single-node skeleton are merged into the target skeleton without asking. This behavior can be changed to again show a merge UI if the single-node skeleton has annotations (behavior so far) through a new entry in the Tracing section of the settings widget. Graph widget: - New layout modes "dagre", "cola", "spread" and "springy". The first is based on DAGs (directed acyclic graphs) and the last three are force-directed. To note that "spread" will evenly layout neurons in trying to occupy as much space as possible, and also leads to symmetric-looking graphs when rendering multiple disconnected graphs of e.g. left and right homologous neurons. Try it. Connectivity matrix: - Descending and ascending sorting is now available for all sorting modes. - The new 'order of other' sorting mode will try to follow the column order for rows and vice versa. If skeletons are not found in the reference dimension, they are pushed to the end. Selection table: - When changing the color of a neuron, all other selected neurons can be colored at the same time, when the new 'all selected' checkbox (right above the color wheel) is checked. Neuron sarch: - The "select all" checkbox now does what it says and selects all neurons in the results set. - Pagination now works like in other widgets and the number of elements per page can be adjusted. - Annotations are not loaded by default anymore, but can be shown with the help of the new "Show annotations" checkbox. Miscellaneous: - When a connector is selected, basic information about it is displayed at the top of the window (where otherwise the neuron name is displayed). - A neuron search result's annotation list is now kept in sync with the rest of the widgets. If annotations change on a listed neuron or annotation, the search query is re-done. - If only transparency is changed in the batch color picker of the Selection Table, the transparency alone (and not the color) of the target skeletons will be updated. To also update the skeleton color, the color has to be changed in the color picker, too. Administration: - Adding custom code to CATMAID's front end is now easier: Add file names to the STATIC_EXTENSION_FILES array variable and have your web-server point the URL defined in STATIC_EXTENSION_URL (defaults to /staticext/) to the folder were those files live. CATMAID will then load those files after its own files. Bug fixes --------- - Nodes are now correctly scaled in skeleton projection layers. - Neuron navigator now updates if a skeleton is changed (e.g. due to a merge). - 'Sync to' selections to push changes from one widget to another (e.g. 3D viewer controlled by selection table) are now updated correctly, if a selected target is closed. - Changing the order of rows and columns of the connectivity matrix manually does now work like expected. - From within the neuron search removed annotations will now disappear again from the search widget after they are unlinked. - Using the CATMAID coloring scheme in the Selection Table is not random anymore. - CSV files exported from the Connectivity Widget now respect the table ordering and include the target neuron names. - Spheres that intersect in the 3D viewer (e.g. somas) don't appear broken up anymore. - The 3D viewer's SVG export will now correctly calculate the size of exported spheres (e.g. soma tags). | 11 September 2015, 17:50:01 UTC |
| refs/tags/2015.7.6 | 2015.7.6 | 11c5263 | 2015.7.6 CATMAID now uses the GPLv3 license and moved away from the stricter AGPLv3. This move was discussed with all previous contributors and agreed on. See the corresponding commit for more details. Contributors: Albert Cardona, Andrew Champion, Tom Kazimiers Notes ----- This release includes database changes that require manual intervention if you are upgrading from an existing installation. A new dependency is now required: PostGIS, an extension to PostgreSQL. After its installation, it has to be activated for the CATMAID database. To do so, connect to the database using a Postgres system user. Assuming a Postgres system user named "postgres" and a CATMAID database named "catmaid", this could be done by calling sudo -u postgres psql -d catmaid Being connected to the database, PostGIS can be enabled by executing CREATE EXTENSION postgis; Now PostGIS is enabled and the connection can be closed again. Now a regular update can be performed. Please note that this update can take quite some time to complete. On bigger neuron tracing installations, multiple hours are realistic. Features and enhancements ------------------------- Key shortcuts / mouse operations: - Ctrl + mouse wheel now zooms the stack, while shift zooms by smaller increments. - Pressing X in the tracing tool will begin measuring distance from the current cursor position. The mouse wheel can be used to measure along the stack Z axis. Clicking will close the measurement tool and show the final distance in the status bar. ESC cancels the tool. Multi-view tracing and virtual nodes: - Orthogonal views on a regular XY stack can now also be used for neuron reconstruction. If they are available as CATMAID stacks and opened while the tracing tool is activated, tracing data will be shown in the respective orthogonal views as well. Tracing can be done in these views just like in the regular XY view. - When tracing, it is not required anymore to place a node in every section. If no node has been placed in a section, CATMAID will place a so called virtual node where the skeleton and the section meet. If this virtual node is modified in any way, e.g. tagging, joining, moving, etc. it will be created. This also slightly changes the way reviews work. Review information is only stored on real nodes. - The review widget has a new settings: in-between node step. It specifies how many sections can be skipped between adjacent real nodes. This is done with respect to the currently focused stack. This stack is also used to determine in which direction to move to look beyond the start of a segment. Stack viewer: - Other stacks in a project can be added to an open stack view by selecting the "Add to focused viewer" option from the stacks menu. This allows multiple stacks to exist in the same view like overlays, while accounting for differences in translation and resolution. The navigator will expand the available zoom levels to accomodate the maximum and minimum zoom possible in all of the open stacks. - Tile layers for stacks added to a viewer can be removed from a viewer via an "x" in the tile layer control. - Multiple viewers into the same stack can now be opened. - Each stack viewer can be toggled between coupling its navigation with other open stack viewers. Toggle this via the "Navigate with project" checkbox in the tile layer control. Tile layer: - New filter (WebGL only): intensity thresholded transparency 3D Viewer: - Connector restriction can now explicitly be turned on and off with a pull down list. One can select between "Show all" (i.e. restriction turned off), "All shared connectors" will only show connectors with partners in the current selection and "All pre->post connectors" will only allow connectors with at least one presynaptic partner and one postsynaptic partner in the current selection. The last option, "All group shared" allows to select two skeleton sources (e.g. two selection table) and it will only show connectors that are part of the 3D viewer and that connect between both selected groups of skeletons. There is also a pre->post enforcing variant of it. Neuron search: - The name displayed for neurons now follows the same naming mechanism used for other widgets. It can be controlled through the settings widget and will automatically update if a neuron name is changed. Miscellaneous: - In the connectivity widget, upstream and downstream thresholds can now be set at once for all seed neurons. Two drop down controls used for this will be displayed if there is more than one seed neuron. - Treenode Table refurbishing: far faster, supports multiple skeletons, can do tag search with regular expressions and lists the skeleton treenode ID. - Rows and columns of the connectivity matrix can now be moved around with little buttons that appear when the mouse is over row and column header cells. - There are now three options to change focus if a pointer enters a window: don't change focus (how it has been so far), focus stacks (will activate stacks when hovered, but won't change focus for other windows) and focus all (will change focus to every window hovered). The default will be stack focus follows the pointer. The settings widget makes these options available in general settings area. - There are three new controls in the split/merge dialog: Toggle the display of input and output markers on neurons in the embedded 3D viewer and select which shading method is used (default: "active node split"). Alternatively, "Strahler index" coloring can be used, which helps with depth perception. - Attempting to reload a CATMAID browser tab or go back in history, will now result in a warning dialog, asking for confirmation. It makes clear that CATMAID's window layout and content won't be saved if the acton isn't canceled. Administration: - Now that virtual nodes are available, existing database can (but don't have to) be optimized. A new management command will look for straight skeleton parts that are not referenced in any way and prunes them. In other words, if there are three successive collinear nodes and the middle one is not referenced, it will be removed. manage.py catmaid_prune_skeletons Bug fixes --------- - The Neuron Search widget doesn't throw an error anymore when a neuron listed in it is merged. - There is no longer a race condition in the database during concurrent split/merge of a skeleton and creation of a treenode in that skeleton. While this is not a comprehensive guarantee of conflict-free concurrency, it does remove the most likely scenario resulting in corruption of the database model. | 06 July 2015, 17:09:48 UTC |
| refs/tags/2015.7.31 | 2015.7.31 | 8e6cc8d | 2015.7.31 Contributors: Albert Cardona, Andrew Champion, Tom Kazimiers Features and enhancements ------------------------- Key shortcuts / mouse operations: - Ctrl + [ or ] now navigates to the next real (non-virtual) parent or child of the active node, respectively. Connectivity widget: - Upstream and downstream partners can now be filtered by synaptic confidence in addition to synaptic count. Synaptic confidence filtering is applied before count filtering. Confidence is taken to be the minimum of the presynaptic and postsynaptic connector confidence. 3D Viewer: - Tags matching a custom regex can be shown as handle spheres in addition to tags containing "uncertain" or "end". Note that after entering the regex in the "View Settings" tab the viewer must be refreshed from the "Main" tab before tag spheres are updated. - The active node marker now resizes based on the radius of the active node. - The active node marker can now optionally always be drawn on top of other objects, even if it is occluded. Miscellaneous: - A default neuron name can now be specified in the settings widget. Similar to annotations, the pattern "{nX}" can be used to add an automatically incrementing number to each new neuron created, starting at X. Omitting X will be interpreted to start from 1. This default name does not persist between sessions. - Neuron navigator: neuron name and annotation search are now case-insensitive. - The client now checks every 15 minutes whether it is the same version as the server. If not, an error dialog is shown prompting the user to refresh their browser. - It is now possible to show a projection of the active skeleton in the tracing overlay. All nodes will be displayed in the current slice, but no interaction is allowed with them. This feature can be useful to get more context on the current location in the active skeleton. This mode can be toggled with F10 or through a new entry in the settings (Tracing Overlay > Active skeleton projection), where different parameters can be adjusted. The color for the upstream and downstream part can be independently changed and various shading modes can be selected (plain color, Z distance transparency, Strahler based transparency or cut off). Bug fixes --------- - 3D viewer: the correct synapse colors are now used when connectors are restricted. - If annotations are added or removed, annotation search widgets are updated correctly. You can now search for newly created annotations without having to open a new search widget. - The order of the selection table is now remembered before it is refreshed. - Connectivity widget: common partners filtering now correctly enforces that partners are partnered with all target neurons, not just any two. - Review widget: the skipped node warning will now only show up when in fact more nodes have been skipped than allowed. - Fixed a vulnerability that allowed any user with "browse" access permissions to any project to execute arbitrary SQL statements on the CATMAID database. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJVu8kxAAoJEAganiFb3SCDVrYP/jbuAPF/YJKVOKKlgEi2F3o8 1jXo+Q+tm65PODfnVx/nLBQWHzb51HUa1X+kzIacXN/TQJ+CR2XG3K5T2empyhV/ CnzKLmIFRCk18Ft/IZisEvpqOA9xvaIsSI/RpOUvjPGxQXFAaqHpI5rqR/0x9pnS IlvR90ansD+nVoIvqyrfPTI33dafRBzdICNV3/+YQPxLF9bJ3vulE8DdNB9eY61W ZWPPDkbthpNVB/roERAfsMv5yZIDLzl9SDgg94AUvTEtuNOWtmRCuWFprMdrj72s zbrugmIHxt2rIXjywzteMRwIjvNf1RZBiRBpmP/U3T62V8izlmWhuja2jhbv10pf n4Jzar6g9vXS6QDcvd8+wxauZU3UKJ3l4Kw0mX4lUo/6j5MCX3tFmhaH3f8TWpyQ wyajbXKaaPxjFdF5kB7ktnaR7RPpDnZcKZpWCYHQ1bVyi1kNgkHnFZCx5Mf/Sqtz wlpGTHz1/zaoaAxH9IFAyzhCP8cxzrTJvOniVwbTx3AUCQ9lLBeYcXU6OWx2Y8/U oIk/WPsIUUMkMMPWgXDSANWzQO9jnzMQvs/uuYs1KXHhyJr3isdcS0Zq98HeVR9Z RHyk1VR3yRjRd/S5+IQ34rkupMZPGx71waqAg/uL4uyWx9TT/72ymBxHkSHy5P1O emee9PPaHcwFBQuWw6PA =K+Yw -----END PGP SIGNATURE----- | 31 July 2015, 19:14:10 UTC |
| refs/tags/2015.7.17 | 2015.7.17 | 87084a8 | 2015.7.17 Contributors: Albert Cardona, Andrew Champion, Tom Kazimiers Features and enhancements ------------------------- Connectivity widget: - Partners can now be filtered by a minimum threshold on number of nodes, rather than only being able to filter single-node partners. - The user's review team is now an option in the partner review filter. - Changing the review filter no longer reloads the entire widget. - Many small performance improvements. Selection table: - The table layout has been streamlined with other tables in CATMAID. All columns except 'action columns' can now be used for sorting. Pagination is now done with the buttons to the right above and below the table, the page length can now be adjusted, too. The summary info button moved into the button panel while the filter input is now part of the table. - It is now possible to add a new annotation to individual neurons without changing the current selection. This can be done with the little tag icon in the actions column on the right. The former info button was replaced by a small 'i' icon and clicking the folder icon in the same column will open a Neuron Navigator window for the respective neuron. - All visibility related colums can be hidden with a new checkbox in the button panel. This might be useful to save space if a selection table is not used to control a 3D viewer. Miscellaneous: - Neuron search: annotations can now be searched for those by users in the review team. - Log: entries can now be filtered to include only actions from the user's review team. - The maximum number of nodes returned to the tracing overlay is now configurable as a server setting: NODE_LIST_MAXIMUM_COUNT (default 5000). - Group graph: a new lock buttons in the Selection tab allows to lock selected nodes, so that their position doesn't change until they are unlocked again. Bug fixes --------- - Fix display of intermediate nodes on edge between two joined skeletons. - The last lines of the review widget were hidden sometimes. This is not the case anymore. | 17 July 2015, 19:27:38 UTC |
| refs/tags/2015.5.27 | 2015.5.27 | d4b0b97 | 2015.5.27 Bug fixes --------- - Fix radius based neuron selection in tracing window. | 27 May 2015, 22:00:16 UTC |
| refs/tags/2015.5.19 | 2015.5.19 | 426bdff | 2015.5.19 Contributors: Tom Kazimiers Features and enhancements ------------------------- Key shortcuts / mouse operations: - Cycling through open end nodes will now only visit the root node if it is an actual leaf. That is, when it has only one child node and is untagged. 3D Viewer: - A light background shading variant for connectors was added. It uses a darker cyan color which provides more contrast if a white background is used. Miscellaneous: - The location of messages and notifications can be configured in the settings widget. The default location is still the upper right corner. - If the node display limit is hit while panning the field of view in tracing mode, node refresh will be temporary disabled. Once the mouse button is released again an no further panning happens within one second, node update is reset to normal. This allows for smoother panning if many nodes are visible. Bug fixes --------- Review system: - Review teams are now respected when Shift + W is used to jump to the next unreviewed node. 3D viewer: - Skeletons with other coloring than "Source", will now be visible when exported as SVG in the 3D viewer. Miscellaneous: - Skeletons added to a selection table, will now honor the table's "global" settings for pre, post, meta and text visibility. - If an annotation is removed from a neuron, the annotation itself will be deleted, too, if it is not used anywhere else. Now also meta annotations of the deleted annotation will be removed (and their meta annotations...), if they are not used anywhere else. | 19 May 2015, 20:00:22 UTC |
| refs/tags/2015.5.11 | 2015.5.11 | 00240e5 | 2015.5.11 Contributors: Albert Cardona, Andrew Champion, Tom Kazimiers Features and enhancements ------------------------- Connectivity widget: - Partner filtering now supports regular expressions when the first character of the search input is "/". Treenode table: - *REMOVED*: Radii can no longer be edited by clicking on their cell in the table. Connectivity matrix: - The tracing tool has got a new widget: a connectivity matrix. It can be opened with the "M" frame icon next to the button for the connectivity widget. To use it, one has to append skeletons for its rows and columns. Skeletons can also be added as group. Each cell shows two sub-cells, the first one shows the number of synapses from row to column and the second one the number synapses from column to row. When a synapse count number is clicked, a connector selection is opened, that contains the corresponding synapses. Both pre- and post-synaptic count cells can be colored individually. By default a coloring similar to the tracing layer's red and cyan is used. There are also color gradients available to produce heat maps (i.e. color cells based on the actual synapse count). - Graph widget: ability to split neurons by text tag on their skeletons. It's the "Tag" button under the "Subgraph" tab. Enables you to manually define regions on a neuronal arbor (like axon and dendrite, or multiple dendritic domains) and then have them be represented each as a node in the graph. The skeleton will be virtually cut at the nodes containing the tags, with the tagged node belonging to the downstream part (relative to the root node). 3D Viewer: - Color mode "Downstream of tag" is now a shading mode. - New synapse coloring mode "Same as skeleton". If you then hide the skeletons and show only the synapses you will e.g. see spatial tiling of ORN axons, each defining a glomerulus in the larval olfactory lobe. - For PNG and SVG export one can now specify the dimensions of the result files. A dialog shown before exporting asks for width and height. Neuron dendrogram: - The horizontal and vertical spacing between nodes in the neuron dendrogram can now be fine tuned. Administration: - A new tool 'Group membership helper' has been added to add multiple users to multiple groups or to revoke their group membership. This can be used to control access over the data created by individual users. Miscellaneous: - A node-placement-and-radius-edit mode has been added. If enabled through the settings widget (Tracing > "Edit radius after node creation"), the radius for a node will be edited immediately after it has been created. This allows for easier volumetric reconstruction. In this mode, the radius circle editing tool is used to specify the radius. No dialog is shown once a radius is selected for a node and it will only be saved for the new node. - A new connector type ("abutting") can now be created. In contrast to the regular synaptic connector, it can be used to represent the fact that two or more neurons are in abutting processes. For now this mode can be activated through the settings widget (Tracing > "Create abutting connectors"). For abutting connectors the lines representing the links to nodes will appear in a green color. Bug fixes --------- 3D viewer: - Adding and removing neurons and static data lead in some situations to many errors that were displayed on the console (and therefore not visible to most users) and caused minor performance problems. This has been fixed and all data should now be added and removed correctly. - Following the active node should now work much more reliable. Before, it could happen that this stopped working after a second 3D viewer was closed. Connectivity widget: - Fix one cause of sluggish behavior for widgets that have been modified many times. Also fixes repeated alert dialogs when clicking a neuron in the partner tables that no longer exists or does not have any treenodes. Neuron Navigator: - Don't show an error if an invalid regular expression was entered for searching. Instead, color the search box red and show a warning message. | 11 May 2015, 21:20:10 UTC |
| refs/tags/2015.3.31 | 2015.3.31 | 126739e | Release 2015.3.31 Contributors: Albert Cardona, Andrew Champion, Tom Kazimiers, Stephan Gerhard Features and enhancements ------------------------- Key shortcuts / mouse operations: - Shift+T removes all tags from the currently active node. - After using R to go the nearest open leaf, shift+R cycles through other open leaves in the skeleton in order of ascending distance from the starting location. Combining alt with these operations orders open leaves by most recent creation instead of distance. - Ctrl+Y removes the active skeleton from the last used selection widget. - Shift+Y selects skeletons within a radius of the active node in the tracing layer and adds them to the last used selection widget. Ctrl+shift+Y works in the same way to remove skeletons from the last used selection widget. - If the next (or previous) branch/end point is already selected when V (or B) is pressed, the view will center on it nevertheless. - If the mouse is over the stack when zooming, the view will recenter so that the same stack location remains under the mouse at the new scale. - During review, Q and W during will refocus on the last reviewed neuron if review is interrupted (another node is selected), regardless of the auto centering setting. If one looks beyond the current segment, the last reviewed node will be selected by Q and W as well, but auto centering is respected. Review system: - New "Reviewer Team" system allows filtering reviews in visualizations and statistics to include only those by particular reviewers. Each user can control which reviewers to include in her team. A date can be configured for each reviewer in the team, so that only reviews from that reviewer after this date are included. * A user's reviewer team is configured through the Settings widget. * The review widget includes a team column between the user and union columns. * The percent reviewed column in the selection widget can be set to team or union. * Team review coloring is available in the 3D viewer and group graph. 3D viewer: - With Ctrl + mouse wheel, only the camera is moved in target direction, the target stays fixed. If Alt + mouse wheel is used, the target moves as well. - The CSV export not also includes the parent ID for each node, which can be used to reconstruct the topological tree. - The auto-created selection widget is now 50% smaller, giving more vertical space to the 3D viewer. - With the help of controls of the Animation tab, simple animations can be played. Currently, rotation around the X, Y and Z axis as well as the current "up" direction of the camera. is supported. The back-and-forth mode will reverse rotation direction once a full circle is reached. With the help of the stepwise visibility option, individual neurons can be made visible after a certain amount of time the animation is running. Additionally, neurons can be made sequentially visible after each rotation. - Animations can also be exported as WebM movie file. The "Export animation" button in the Export tab, will show a dialog with basic export settings. Like with the other view export options, the current 3D view setup is used. The frame size can be adjusted in the export dialog. Creating the file can take some seconds and currently only works for the Chrome browser (due to the lack of WebP support in others). The resulting WebM video file can be converted to any other format using e.g. VLC player, if needed. - New shading mode "synapse-free chunks". Has one parameter, the minimum amount of synapse-free cable to consider between two consecutive synapses, adjustable from the "Shading Parameters" tab. - New shading mode "dendritic backbone". Depends on 'microtubules end' tags, or will approximate twigs by using the Strahler number entered in the "Shading Parameters" tab. - The view settings tab now contains a control to scale the size of the node handles (e.g. active node, special tags). Tile layer: - Tiles can now be rendered with WebGL, which enables new visualization features and fixes some flickering issues. Enable via "Prefer WebGL Layers" in Settings. The WebGL renderer is currently considered experimental and may have stability issues on some clients. See https://github.com/acardona/CATMAID/issues/186#issuecomment-86540706 for details on using WebGL layers with your image stack host. - The blend mode used to combine stacks and overlays is now configurable when using WebGL. This greatly improves visualization of confocal and other multichannel data. Blend mode is selectable from the layers control, activated via the toggle at the bottom left of the stack view. - Filters can be applied to layers when using WebGL. Filters can be added and removed from layers through the layers control. Available filters currently include: * Gaussian blur * Color inversion * Brightness, contrast and saturation adjustment * Color matrix transform Connectivity widget: - It is now possible to remove added neurons again. Each row of the table of target neurons now contains a small 'x' icon in the first column to remove it. - The selection column is not included anymore in the CSV export. Analyze Arbor: - Options are provided to approximate twigs by using a branch Strahler number defined in the "Options". - Dimensions of the pie charts and XY plots is now configurable from the "Options" dialog. Graph widget: - New button to "Clone" the graph widget: opens a new widget with identical content. - New buttons to "Save" and "Open..." to/from JSON, so that complex graphs can be reloaded later on. Skeletons not present in the database are not loaded. Miscellaneous: - Selecting tags for highlighting in the neuron dendrogram - Synchronization between widgets was improved. Deleting a neuron in one widget, will remove it from other widgets as well. - Hovering over the CATMAID text on the front page will display CATMAID's version. Admin: - For projects, stacks, overlays and data views there is now the option to duplicate objects from within the admin view. To copy objects without their relations, there is now a new action in the list view's action menu. To duplicate an entity with its relations, select the object and use the "save as new" button. Export: - A basic JSON export of all treenodes and connectors of the selected neurons is now possible. Bug fixes --------- Tracing overlay: - Trying to remove a non-existent tag from a node now doesn't show an error dialog anymore, but only a notification. Key shortcuts / mouse operations: - Fix bug where tagged nodes were not considered open by R regardless of tag content. Neuron search: - Make neuron names wrap and use the next line, if there is not enough space for it. This makes the table not expand in width until the name fits anymore. 3D viewer: - Picking a synapse or other selectable elements is now more robust and now works also in orthographic mode. - The projection mode (orthographic or perspective) is now also stored in a saved view. - The 3D viewer's drawing canvas is now correctly sized again. Since the tab panel has been introduced, the 3D viewer has been too high. Now the pre-defined views (XY, XZ, ZY, ZX) are display correctly again, i.e. the whole bounding box is now seen again. - Performance enhancement when smoothing skeletons with a Gaussian by avoiding to update the same Vector3 instances twice. Reviews: - Pressing 'E' during review will now go to the next unreviewed segment as seen from the currently reviewed one. Before, the first unreviewed segment as seen from the top of the table was selected. - Pressing 'Q' on the first node (leaf) brings one back one section to check if the segment really ends. Pressing 'W' afterwards now brings one back to the first node, not the second like it has been before. Connectivity widget: - CSV export works again. Miscellaneous: - Vertical resizing of widgets now doesn't lead to strange size changes anymore. - An alternative DVID tile source was added to support its multiscale API. | 01 April 2015, 19:29:36 UTC |
| refs/tags/2015.12.21 | 2015.12.21 | 594495b | 2015.12.21 ========== Contributors: Albert Cardona, Andrew Champion, Eric Trautman, Tom Kazimiers Features and enhancements ------------------------- Selection table: - A new option ("Append with batch color") allows to override the color and opacity of appended skeletons with the current batch color and batch opacity. It is deselected by default. - Clearing the table doesn't ask for confirmation anymore. This has been removed for consistency with other widgets and because of the now available option to save/open skeleton lists. New widget "Synapse Distribution Plot": - For one or more neurons, plot distances of postsynaptic sites relative to an axon initial segment, represented by a skeleton node that is either computed or given via text tags. Each row represents the inputs contributed by a presynaptic arbor. Presynaptic arbors (rows) are sorted from more to less synapses. Presynaptic arbors can be filtered (i.e. hidden away) by a threshold on the number of inputs each provides, or by being listed in another widget that has selected skeletons. Individual synapses take by default the color of the postsynaptic arbor (that is, the arbors added via "Append"), but can be colored as well according to neuron colors in another widget. Click on an individual postsynaptic site to go to the corresponding skeleton node. Click on the legend to jump to the skeleton node representing the axon initial segment, relative to which all distance measurements where made. All presynaptic neurons are available in a separate skeleton source for each widget to pull neurons from. New widget "Synapse Fraction": - For one or more neurons, render a normalized stacked bar chart with the number of synapses for/from each partner skeletons (directly either upstream or downstream). Can group partner skeletons: add groups by selecting a skeleton source (another widget listing skeletons). Click on the legend to edit (title, color) the group, or remove it. Click on the legend to go to the nearest node in the partner skeleton. To open this new widget, open a connectivity widget and push the button named "Open partner chart". Settings widget: - Persistent settings are now scoped, so that default settings may be configured for an entire CATMAID instance ("global"), for each project ("project"), for each user ("user"), and for each user for each project ("session"). Only administrators have access to change project settings, and only superusers have access to change global settings. This allows, for example, administrators to set up recommended defaults for projects so that users only need to adjust their settings where their preferences differ from the project defaults. A selection box for which scope to adjust is at the top of the settings widget. Persistent settings will display information about scopes and defaults when hovering over them with the cursor. - Administrators may also lock persistent settings so that global or project defaults can not be changed by users. Graph widget: - In the main tab, a new remove button removes skeletons in the selected skeleton source from the graph. 3D Viewer: - Added new buttons under the "Export" tab to export connectors and synapses as CSV. And Skeletons are now exported to CSV with a new column, the radius at each skeleton node, and another new column for the neuron name as rendered by the NeuronNameService (controlled by the Settings). The connectors CSV contains, for each row, the connector ID, the treenode ID, the skeleton ID and the relation ID, mimicking the treenode_connector table. The synapses CSV exports two files: 1. The skeleton ID vs the neuron name 2. The list of synaptic relations of any arbor visible in the 3D Viewer, with columns for the presynaptic skeleton ID, its treenode ID emitting the synapse, the postsynaptic skeleton ID, and its treenode ID that receives the synapse. Review system: - Creation, deletion, and edition of synapses and relations now causes related nodes to become unreviewed. Changes to presynaptic relations or the connector itself cause all related treenodes to become unreviewed, while changes to postsynaptic relations affect only that specific related treenode. Changes to other connection relations (abutment, etc.) behave like presynaptic relations, propagating to all related treenodes. Skeleton source subscriptions: - So far some widgets allowed to synchronize their skeleton list along with individual property changes. This was done through a "Sync to" selection which pushed this information to other widgets. This has now been replaced with a subscription option. Many widgets allow now to react to changes in skeleton lists in other widgets. Widgets supporting this got a new small chain icon in their title bar with which a subscription management user interface can be shown and hidden. Widgets that contain multiple sources, like the connectivity matrix, have one icon per source. A hover title will show which one to use for each source. - The UI allows to add subscriptions to multiple sources which can then be combined through set operations. Currently sources are combined in a strict left-associative fashion from top to bottom of the list. When "Override existing" is checked, widget local skeletons are not used when subscriptions are refreshed and will subsequently be removed. Otherwise, the local set is united with the first subscription before all other subscription sources are applied. - The scope of individual subscriptions can be adjusted: By default each subscription reacts to skeletons added, removed and updated in a source. The "Filter" selection allows to listen to only one of these events. For instance, subscribing to the active skeleton with the "Only additions" filter, allows to collect skeletons selected active skeletons without removing them again from a widget. - By default, only selected skeletons are subscribed to. This means if a skeleton becomes unselected in a source it is removed from the target widget. If the "Only selected" checkbox is unchecked, also unselected skeletons are added to a target widget. They are removed when skeletons are removed from the source and their selection state is synced. - All widget still feature the "From [Source] Append/Clear/Refresh" work-flow. The subscription UI's "Pull" button does the same as the regular "Append" button: a one-time sync from a source. Miscellaneous: - Many tracing widgets now allow a user to hide their controls. A little gear icon in their title bar toggles their visibility. - Rather than only specifying annotations that are used as successive fallbacks for labeling neurons, neuron labels can now be specified as arbitrary combinations of annotation-based components using a format string. This is still configured in the annotations section of the settings widget. - Volumes can now be edited when clicked on in the volume widget. This will also display the edited volume as layer in the active stack viewer. - Moving a node in the tracing overlay now updates its position in the database as soon as the mouse is released, rather than waiting until the section changes. - Changes to the CATMAID API are now documented in `API_CHANGELOG.md`. - A docker image of a running CATMAID instance is now available for evaluating or developing CATMAID without needing to perform a complete install. The latest release is available via the "stable" tag, and the current development version is available via the "latest" tag. To try it: docker run -p 8080:80 aschampion/catmaid Then point your browser to http://localhost:8080. The default superuser has username "admin" and password "admin". Bug fixes --------- - API testing URL generated by Swagger (used for the API documentation at /apis) now respect a sub-directory that CATMAID might run from. - Fixed near active node shading in the 3D viewer. - Pre- and post-synaptic edges in the tracing overlay now update when dragging a related treenode. API changes ----------- The CATMAID API now authorizes requests using an API token tied to your account instead of your username and password. To obtain this token, open the CATMAID client in your browser, hover your cursor over your name (next to the "Logout" link), and click "Get API token". As a security measure, you will be prompted to re-enter your password, then shown your token string. To use the API token, set the HTTP `X-Authorization` header on all of your API requests to be 'Token', a space, and the token string, e.g.: X-Authorization: Token 9944b09199c62bcf9418ad846dd0e4bbdfc6ee4b Additions: - `GET /projects/`: List projects visible to the requesting user. - `GET /client/datastores/`: List key-value store datastores used by the client. - `POST /client/datastores/`: Create a key-value store datastore for the client. - `DELETE /client/datastores/{name}`: Delete a key-value store datastore for the client. - `GET /client/datastores/{name}/`: List key-value data in a datastore for the client. - `PUT /client/datastores/{name}/`: Create or replace a key-value data entry for the client. - `POST /{project_id}/volumes/{volume_id}/`: Get detailed information on a spatial volume or set its properties. Modifications: `GET /{project_id}/annotations/`: - Params are now correctly documented as form rather than query params. `POST /{project_id}/annotations/`: - Params are now correctly documented as form rather than query params. `POST /{project_id}/annotations/forskeletons`: - Params are now correctly documented as form rather than query params. `POST /{project_id}/skeletons/connectivity`: - `boolean_op` form param now expects string "AND" or "OR" rather than "logic-AND" or "logic-OR". `POST /{project_id}/volumes/add`: - Params are now correctly documented as form rather than query params. Deprecations: None. Removals: None. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJWeElKAAoJEAganiFb3SCDFZMQAKigf23zW6luG/uGs75v4U5D 6+N6EoPdUC2q2SYfjc24EQhkmwgUeGYuaatl8HUga17hJzIQltKRpexwFdKm5cDc XOBnDHyUOMkhMngiCzw/hocLIF9eVZWRHnIGdLcrY2/1uCs8/btOqraSsLzoKo1u NaEmEkNrVAxRdzl2wWriMCUgcHv0PUNzI0TUvOmcyYi54JnzRo9v7k7EHa6E3dY4 u7QcLFAAXS2mU11k5rinK0j0EEicasE4rBCz6WZ4cepE44jl7z06HUg043nSssLt PhpwXC7dL6Uk6onx0+GYDzHKEySTqBi1eYELcMSADRxbpwMRBudF1hvj0khj5J8x NHi62/TWuMQIxMdKB8ZHPeWoGyxbOy+nEfmFJZ8pi0t0g9pG8ihZ20YE6OGKTXS2 L/oobgTxrdB53WOb35wZDbp0LDGTmTdauRwC1PwBd01fUy0dmXOm9ejdvE9lX/fw XQKojAtrhj9p+RdUADxQvwiEqaBUC1fMcCPI7MWkvV4vQcoxSTOTGg9a10uUUtUN c0syndrU3dHL2/xGGtQ53QtUR3A9i++1X+v8qsDmYshcEm0l52g5m7uNN6j3Z4m0 0CJE7k+TFy5hlMdiplglcp+TxsnQ4NGP8dSnxd0uQedt8PJY5i+nEujARmPg6ZEv jJ56X+Itedwh7Wece5GO =QjCQ -----END PGP SIGNATURE----- | 21 December 2015, 18:44:03 UTC |
| refs/tags/2015.11.16 | 2015.11.16 | 4aac7ea | 2015.11.16 ========== Contributors: Albert Cardona, Andrew Champion, Tom Kazimiers Features and enhancements ------------------------- Key shortcuts / mouse operations: - Pressing \ now brings up a dialog to go to the nearest node with a label matching a query regex. If a node is active, this search is limited to the active skeleton. Shift + \ cycles through matching nodes in ascending distance order. Ctrl + \ repeats the last search regex without prompting. - Deleting a virtual node with DELETE or Ctrl+Shift+click instead suppresses the virtual node. Suppressed virtual nodes are skipped during review. A setting is available to also skip suppressed virtual nodes during normal navigation with [ and ]. Selection table: - Batch coloring is now much quicker. - If the batch color button is pressed a second time the color picker will not only close but also will the batch coloring be re-applied. This won't happen if the color picker is closed by clicking somewhere else. - The status text line at the bottom of the table includes now the number of selected neurons. This is helpful when a filter is active and more neurons are selected than visible. - Sorting for visibility columns has been removed. - Neurons part of a Selection Table can now also be filtered based on annotations. This can be done with the help of the input field next to the name filter. Like with the name filter input, pressing the Enter key will activate both filters and starting with a slash character ("/") will make the input be treated as a regular expression (to e.g. only show neurons that are annotated with a1 and b2, use "/a1|b2"). For now no meta-annotations are taken into account. - With the help of the new "Open" and "Close" buttons, skeleton lists can be stored into JSON files as well as loaded from them. Along with each skeleton ID, the current color and opacity is stored. Skeleton projection layer - With the new "Skeleton color gradient" coloring mode, the skeleton's tracing color (currently only yellow fo the active skeleton) is used for coloring. It fades into downstream and upstream colors, respectively (which are black and white by default). - Nodes can be selected by placing the mouse close to them (regardless if displayed or not) and pressing 'g'. If no node is found in close proximity (<50px screen space), the tracing layer's node selection is used. Graph widget: - Synapses can be filtered from edges based on their confidence. The confidence threshold is applied to the minimum of the pre- and post-synaptic relation confidences. Confidence filtering is applied prior to synapse count filtering. - Synapse count coloring on edges can now be configured independently from edge colors. Volumes: - A new widget, the Volume Manager, allows to create and list volumetric geometries. These geometries are not yet displayable and for now only box volumes can be created. The widget is available through a new 3D box icon, last in the list of tracing tool widgets. - New nodes can now be tested for intersection with a certain volume. The Tracing section of the settings widget allows to choose a volume against which new nodes will be tested. If they are outside of it, a warning will be shown. Neuron Search: - Partial annotations as well as regular expressions are now supported for searching. If the text entered in an 'annotated' search field matches a single existing annotation (i.e. one that would also show up in the auto-completion), it is used as search constraint, just like before. However, if no matching annotation was found, the input text is treated as a regular expression on annotation names if it starts with a slash character ('/'), otherwise it is treated as a regular search pattern over all annotations. For instance, finding all things that are are annotated by either A1 or B2 would look like '/A1|B2' or requiring annotations that end on 'xyz' could be searched for by '/xyz$'. This also works with sub-annotation queries. 3D viewer: - Different neuron visibility modes are now available for animations. A drop down list replaces the check-box and an option dialog is shown if a particular animation mode requires user input. Besides the 'show one neuron per rotation' mode, there is now also the 'Show n neurons per rotation' mode and a mode which uses a pattern to explicitly define the visibility of particular neurons after a particular rotation. The animation export now uses the visibility mode selected in the 3D viewer. Administration: - CATMAID has been able to use DVID as a project/stack back-end and as a image source for quite a wile now. To make the latter option easier to setup, a new admin tool is available to create CATMAID stacks based on a DVID server. It can be found in the "Custom views" section of CATMAID's admin interface, labeled as "DVID stack importer". With the help of this tool on can inspect all available repositories and data instances on a DVID server and create a stack based on one data instance. CATMAID will make sure that all pre-conditions are met by a stack created this way. Miscellaneous: - By default new widgets will now select the last widget created as skeleton source. If wanted, this can be adjusted to the previous behavior (always select 'Active skeleton') through the 'Auto-select widget created last as source for new widgets' option in the settings widget. - Multiple stacks opened through a URL can now optionally be opened in the same stack viewer window by adding "&composite=1" to the URL. - If an already reviewed node is moved it will now become unreviewed again. - Links clicked in the message menu will now open in a new page. Bug fixes --------- - The skeleton projection layer will now update automatically on skeleton changes like new or removed nodes as well as splits and merges. It will also not complain anymore if a connector was selected. - Text rendered in the 3D viewer is now upright again (instead of upside-down). | 16 November 2015, 20:27:39 UTC |
| refs/tags/2015.10.19 | 2015.10.19 | db8ed6e | 2015.10.19 ========== Contributors: Albert Cardona, Andrew Champion, Tom Kazimiers Features and enhancements ------------------------- Scripting: - The widget instance associated with the focused window can be retrieved with the convenience function `CATMAID.front()`. Orthogonal views and multi-channel data: - Stack groups can be used to relate different stacks to each other within one project, e.g. to make clear that some stacks are different orthogonal views or different channels of the same dataset. If there are stack groups defined in a project, they are for now available through the "Projects" menu, which provides sub-menus for stacks and stack groups for each project. When opened, the stacks of a channel based stack groups are added as layers to the first stack. Ortho-view stacks are all opened in a separate stack viewer. - If a stack group consists of the three different orthogonal views for a dataset, the window layout is adapted automatically as soon as the stack group is opened. The layout will be a four-pane layout in which the left half of the screen is the XY view on top of the XZ view and the right half of the screen is the ZY view on top of a selection table. - Since stack group are instances of the 'stackgroup' class, they can be referenced from within ontologies. All projects now have a 'stackgroup' class and the relations 'has_view' and 'has_channel' created by default. They are also created for projects that don't have them, yet. - Stack groups can be created and managed from with the admin interface through either the new Stack group page or while editing/creating a stack. 3D viewer: - Skeletons can be shaded by distance from a plane through the active node. The plane can either be a Z-plane in project space or a plane normal to the ray from the camera to the active node. Tile layer: - WebGL rendering is now compatible with orthogonal views. - Tiles can now be rendered either with linear pixel interpolation (previous default behavior) or nearest neighbor interpolation. This is controlled by the "Image tile interpolation" setting. Graph widget: - When growing by circles, the set of neurons added can be filtered to include only those with annotations matching a regex. Miscellaneous: - A new color picker replaces the color wheel. The new control hovers over other elements so it can be moved, has color memory slots, defaults to a smaller size and can be resized to show input elements for different color spaces. To save a color in a memory slot, click on the rectangle containing the small circle next to the memory slots. - Documentation for some HTTP API endpoints is now available from your CATMAID server at the `/apis/` URL.
