not sure if this ever got answered. The gcs is an atlas we use to label individual subjects. If you have run your subject through recon-all there should be *.annot files in the subject's label dir that correspond to the individual subject parcellations. You can read those in to matlab or python (or convert them to labels if you are interested in individual parcels instead of the whole thing)

Hello FreeSurfer Developers,
I'm attempting to using DK atlas as label to mask my global brain index. I found the lh/rh.DKTatlas4 0.gcs in /freesurfer/average folder. But I don't know how to read this gcs files. Can I convert this file from gcs to gifit or annot version. Then using MRIread or nilabel to read it label files?
