### Dependencies
- For the current work, we rely on brainspace (download here: https://brainspace.readthedocs.io/en/latest/pages/install.html), surfstat: https://mica-mni.github.io/surfstat/, scientific colourmaps: https://www.fabiocrameri.ch/colourmaps/, raincloudplots: https://github.com/RainCloudPlots/RainCloudPlots; abagen https://abagen.readthedocs.io/en/stable/ and NeuroSynth https://www.neurosynth.org, MPC code: https://github.com/MICA-MNI/micaopen/tree/master/MPC
- For the analyses we use surfaces constructed from freesurfer (fsaverage 5) and Schaefer 400 (7 networks) parcel solution.
### Step by step
Check out structure and function using the following steps. <br />
1. First we correlated the rows of the structural and functional matrices.
2. We did the same for the mean functional/structural matrix with their heritability maps - as well as heritability of structure-function coupling, and for macaques.
3. To compare humans and macaque data on the surface, we used Ting Xu's code and approach: https://github.com/CNG-LAB/PRIME-DE
4. To evaluate the topology we used brainspace to construct gradients.
5. For decoding we combined maps from step 1 and 4 in a 2D framework and mapped cytoarchitecture/functional communities, as well as
phylogenetic models (dual origin and functional reorganisation between macaques and humans), transcriptomic data (AHBA, using abagen) and
functional terms (NeuroSynth).
### Manuscript data
- Main data is from HCP and PRIME-DE which is openly available.
- Auxiliary data is in a .mat file. Do let me know if you think something is missing.
