hi holly,
you can average labels in a common surface space with
mris_spherical_average. when you say you used mri_surf2vol, though, it
sounds like you have these labels in volume space?
good luck,
oliver

We have an ROI for V1 of each of 10 subjects that we have transformed
onto the surface of fsaverage with mri_surf2vol. Now we would like to
sum these binary masks to produce a single mask with values from 0 to
10 corresponding to the overlap of the individual masks on the average
surface.
Is there a way to do this with freesurfer tools or do we need to
invoke fslmaths from the FSL tools?
Thanks,
Holly
