Dear Freesurfers
As recommended I'm calculating the cortical GM&WM vols from the surfaces.
Using the --excl-ctxgmwm to exclude the GM&WM volume from the segmentations and the --surf-ctx-vol and --surf-wm-vol to respectively compute the GM and WM surface volumes. The problem is that in the aseg.stats file the lines:
# surface-based-volume mm3 lh-cerebral-white-matter
# surface-based-volume mm3 lh-cerebral-cortex
# surface-based-volume mm3 rh-cerebral-white-matter
# surface-based-volume mm3 rh-cerebral-cortex
are not appearing,
I've checked with the volumes using "mris_volume -v lh/rh.pial" and "mris_wm_volume subjID lh/rh -v". Only the volumes from the mris_wm_volume coincide with the ones in the ones in the lines: # Measure lhCorticalWhiteMatter,.....,Left Hemisphere Cortical White Matter Volume, ,mm3 in both hemispheres but not the cortical GM volumes
