Thanks. I ran this command: mris_anatomical_stats subjectID lh pial It gave me a total surface area of 115007 mm^2 I also tried the following command from within the 'label' directory: mris_anatomical_stats -l lh.cortex.label -f lh.cortex.stats -b subjectID lh pial It gave me a total surface

Volume-based registration is fine with subject as you have the same brain that you are registering (ideally such registrations are 6 DOF rigid registrations and any image distortions are corrected for). Surface-based registration is better when comparing across subjects due to the variability in
