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?
