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).

Subject: [Freesurfer] Native volume to fs_average surface
External Email - Use Caution
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.
* mri_vol2surf --src filtered_func_MNI.nii --out filtered_func_surf.mgh
--hemi rh --mni152reg
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
