https://www.templateflow.org/ is a repository of neuroimaging templates (eg. MNI, fsLR) and a python library to pragmatically download them.
This includes volumetric as well as Surface-based Analysis (cifti).
You can find template flow atlases on rhea in /opt/ni_tools/templateflow/
TEMPLATEFLOW_HOME is set to /opt/ni_tools/templateflow/~/.cache/templateflow can be a symbolic link to /opt/ni_tools/templateflow/$TEMPLATEFLOW_HOME to that used in the container -v /opt/ni_tools/templateflow/:/root/.cache/templateflow. This will avoid downloading large files every time the container is run
templateflow uses Git annex to only copy files when requested. Until templateflow.api.get is run a template will only be a stand in empty file. Here's an example of grabbing left and right for all the 32k versions of fsLR
UPMC Certificates can cause problems, especially in docker. Look there if you get SSL errors.
# export HTTPS_PROXY=socks5h://localhost:12345 # deal with rhea python certs issue / man-in-the-middle from upmc
# export REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt
python -c "import templateflow; templateflow.api.get('fsLR', space=None, hemi=['L','R'],density='32k', suffix=['veryinflated','inflated','midthickness','sphere'])"
The results is den-32k files with some size, and the rest still with size 0 (empty).
