[Neuroimaging] [nilearn] map parcellation from Colin space to fsaverage surface

[Noam Peled]

Hello Jan,
In our tool, mmvt.org, we've already used freesurfer on the colin template.
You are welcome to take a look. We are working on the documentation, so
I'll be happy to assist.
Here is an example of fMRI activity projected on colin's semi-inflated
surface:

Best,
