You could also do it pretty easily in matlab or python

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) On 6/12/2020 10:24 AM, Mason Wells wrote:
External Email - Use Caution 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
