You can ask it to sample the maximum along the surface normal over a certain distance. Use --projdist-max. Run mri_vol2surf --help for more info

I've been using mri_vol2surf to move some activation data in MNI space to the fsaverage surface with the following command:
mri_vol2surf --mov MNIvol.nii --projfrac-max 0 1 0.1 --hemi rh --o rh.out.mgz --mni152reg
This works well, but I'm losing a small temporal gyrus cluster that sits close to pial surface. I was assuming this was due to the proximity to the pial surface and resampling, but are there any other options or flags I could use to get this to project successfully?
Thanks very much,
Dan
