Dear Freesurfer experts,
Hello, I am a student currently working in Frank Guenther's lab at Boston University. I am quite new to freesurfer, so forgive me if the following question may be elementary.
I am interested in using freesurfer to compare the level of atrophy (preferably for different brain areas) in an individual subject to several controls. I'm wondering if there is any way to determine the volume of the '?h.pial-outer-smoothed', and corresponding '?h.pial' file generated from running the 'recon-all -s <subj> -localGI' command. The idea is that I could generate a metric representing a general level of atrophy in subjects by comparing these two volumes (or by comparing the '?h.pial-outer-smoothed' to intracranial volume), however, I have been unable to find a way to retrieve these values. Does anyone have any suggestions? I would greatly appreciate any help in this regard.
Thank you for your help!
Best, Riccardo Falsini
