Hi Mason
Yes, you can use mri_vol2surf to go native vol->native surf, then mri_surf2surf to go native surf->group surf
Cheers

HI Matt,
Thanks for the reply. Are you suggesting I go native volume > native surface > fs_average? If so, can you recommend the best can I go from native to group average surface?

You would do that through the subject’s own surface. It does not work very well to map data directly from the volume onto group average surfaces (see e.g. Coalson et al., 2018 PNAS).

Hi experts,
I have some fMRI data that I have pre-processed in Feat. I want to resample a single subject's data to the fs_average surface but unsure of the most optimal way of doing this. At present I am
warping the functional data to the MNI brain in the volume (using FSL's applywarp) and then resampling to fs_average using the following command.
My question is whether you think this is the most appropriate approach, and/or if there is way to move directly from native volume to fs_average surface without needing to go via MNI volume?
Best wishes,
Mason
