When you say "gray matter volume", does it mean you are trying to do a VBM-style analysis? You can't do VBM with FS. You can do an analysis of cortical GM volume in a similar way. When you run mris_preproc, specify "volume" as the --meas

Hello,

Thanks in advance for your patience with what is probably a very basic question!

We would like to run a group analysis with gray matter volume at the voxel level following manual edits, and we are unsure which .mgz file is the proper output to use as the final output from manual edits. We do not have brain.finalsurfs.manedit.mgz files. Which subject file is the recommended output to use for a whole-brain voxel level group analysis after manual edits? I have included a screenshot of an example subject’s /mri directory below.
