# pyradiomics v1.1.0
## Radiomics feature extraction in Python
This is an open-source python package for the extraction of Radiomics features from 2D and 3D images and
binary masks.
Image loading and preprocessing (e.g. resampling and cropping) are first done using `SimpleITK`.
Then, loaded data are converted into numpy arrays for further calculation using feature classes
outlined below.
### Feature Classes
Currently supports the following feature classes:
- First Order Statistics
- Shape-based
- [Gray Level Cooccurence Matrix](https://en.wikipedia.org/wiki/Co-occurrence_matrix) (GLCM)
- [Gray Level Run Length Matrix](http://www.insight-journal.org/browse/publication/231) (GLRLM)
- [Gray Level Size Zone Matrix](https://en.wikipedia.org/wiki/Gray_level_size_zone_matrix) (GLSZM)
### Filter Classes
Aside from the feature classes, there are also some built-in optional filters:
- Laplacian of Gaussian (LoG, based on SimpleITK functionality)
- Wavelet (using the PyWavelets package)
- Square
- Square Root
- Logarithm
- Exponential
### Supporting reproducible extraction
Aside from calculating features, the pyradiomics package includes provenance information in the
output. This information contains information on used image and mask, as well as applied settings
and filters, thereby enabling fully reproducible feature extraction.
### Documentation
For more information, see the sphinx generated documentation available [here](http://pyradiomics.readthedocs.io/).
Alternatively, you can generate the documentation by checking out the master branch and running from the root directory:
python setup.py build_sphinx
The documentation can then be viewed in a browser by opening `PACKAGE_ROOT\build\sphinx\html\index.html`.
Furthermore, an instruction video is available [here](http://radiomics.io/pyradiomics.html).
### Installation
PyRadiomics is OS independent and compatible with both Python 2.7 and Python >=3.4.
To install this package on unix like systems run the following commands from the root directory:
sudo python -m pip install -r requirements.txt
sudo python setup.py install
Detailed installation instructions, as well as instructions for installing PyRadiomics on Windows are available in the
[documentation](http://pyradiomics.readthedocs.io/en/latest/installation.html).
### Docker
PyRadiomics contains three "flavors" of [Dockers](https://www.docker.com/). The first is a command line installation of the `pyradiomics` and `pyradiomicsbatch` command lines. The second is a [Jupyter notebook](http://jupyter.org/) with PyRadiomics pre-installed with example Notebooks. The third is a Ubuntu 16 based Docker for command line and interactive use. To build the Dockers:
docker build -t radiomics/cli .
docker build -t radiomics/notebook -f Dockerfile.notebook .
docker build -t radiomics/cli2 -f Dockerfile.ubuntu .
The `radiomics/notebook` Docker has an exposed volume (`/data`) that can be mapped to the host system directory. For example, to mount the current directory:
docker run --rm -it --publish 8888:8888 -v `pwd`:/data radiomics/notebook
or for a less secure notebook, skip the randomly generated token
docker run --rm -it --publish 8888:8888 -v `pwd`:/data radiomics/notebook start-notebook.sh --NotebookApp.token=''
and open the local webpage at http://localhost:8888/ with the current directory at http://localhost:8888/tree/data.
### Usage
PyRadiomics can be easily used in a Python script through the `featureextractor`
module. Furthermore, PyRadiomics provides two commandline scripts, `pyradiomics`
and `pyradiomicsbatch`, for single image extraction and batchprocessing, respectively.
Finally, a convenient front-end interface is provided as the 'Radiomics'
extension for 3D Slicer, available [here](https://github.com/Radiomics/SlicerRadiomics).
