Hi Bruce,
These subjects were run with an older version of FreeSurfer and don't have ?h.cortex.label. I am afraid I don't see a generating command in the ReconAllDevTable. In ReconAllFilesVsSteps it looks like it is coming from mris_make_surfaces. Can I generate these labels from the old recon-all output?
Cheers,

Hi Morgan,
yes, that seems reasonable. You can start with the ?h.cortex.label and subdivide it into sulcal and gyral to avoid the medial wall.

I would like to obtain a ratio of gyral/sulcal GM/WM boundary surface area. I was wondering if the best solution would be to threshold each subject's ?h.sulc files to form a label that contains all gyral areas and then use mris_anatomical_stats -l to constrain a surface area measurement to this label? I was also wondering if there is a simple way to exclude the medial wall area from consideration in these calculations? Thanks in advance for your time.
