For binarization use mri_binarize. For intersecting, you can use mri_binarize with the --mask option. If you want to add to volumes, you can use fscalc, eg fscalc vol1.mgh sum vol2.mgh -o sum.mgh fscalc has a bunch of options. Run it with -help to see

Hi Freesurfer experts.

Is there any tool to perfom volume calculations? Such binarize a volume, intersect two volumes, sum volumes etc?

Thanks.
