If you want to save it on label format, then mri_cor2label is the right
way to go. Make sure to use the --surf option. If you want them in
separate mgz files, then use mri_binarize with --match

Hi Doug,
Yes, I mean a surface overlay, it is the mgz format. It essentially
has 25 visual areas, shown in the attached. I wanted to split them up,
so that each ROI is its own label. I saw I could use mri_cor2label,
but is there a better way?
Cheers,
Mason

When you say "surface" do you mean a surface overlay or a surface with
xyz and neighbor relations? Assuming you mean an overlay (eg,
something in an mgh or mgz file), you can try fscalc. Or do you have
25 frames in a single file and you want to split them into separate
files? You might be able to convert the mgh/mgz file to nii and use
FSL tools and then convert them back (sometimes works, sometimes not)

Hi Experts,
Apologies if this is a rather simple question. Is there a
FreeSurfer equivalent of fslmaths? I have an atlas overlay that
has 25 visual areas in a single .mgz file. I want to separate each
atlas region into a different file, so that I end up with 25
surface atlas regions. Is there a command that could achieve this?
My next question is whether or not there is a Freesurface command
that can be used to complete surface based correlations. For
example, if I want to check for the overlap between two ROIs. I
have been using fslcc to do this in the volume, but perhaps
freesurfer has something similar to do this on the surface?
Cheers,
Mason
