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.
Cheers,
