Hello Freesurfer’s
I am trying to look at the cortical thickness for a specific ROI on the cortical surface (Primary Auditory Cortex: transverse temporal gyri). I found a specific tutorial (https://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness) however the tutorial assumes I already have an ROI mask created. I was wondering if anyone had any tips on creating an ROI for the cortical surface from the parcellation/annotation files. I know you can “hand-draw” ROI’s in tkmedit or freeview but I would prefer something less subjective that doesn’t rely on my untrained eye and unsteady hand! Thanks in advance.
Best,
Michael S.
Why not just get it from the ?h.aparc.stats file?
