Hello Free Surfer developers,
From my understanding, the volumes provided in the aseg.stats document is not corrected by the head size.
In order to do that, it is recommended to use the ITV and the label ID's:
mri_label_volume -eTIV \ $sdir/transforms/talairach.xfm 1948 \ $sdir/aseg.mgz 17 53
However, I need the corrected volume of the Brain Segmentation Volume without Ventricles, the Total gray matter volume, Left hemisphere cerebral white matter volume, and Right hemisphere cerebral white matter volume, none of which have a label ID.
Is there any way to obtain these corrected volumes in free surfer itself?
Thanks,

No, this was a situation that we were not anticipating. You'll have to do it yourself. If you run asegstats2table, it will create a table that has the BrainSegNotVet and the eTIV
