I have generated surfaces using the the centos4 build (version 5.0)
and want to confirm that my surface-based GM and WM volumes are correct.
For the surface-based GM calculation I originally used 'mris_anatomical_stats -l lh.cortex.label subjectID hemi'
(run from within the 'label' subdirectory) and for WM i used 'mris_wm_volume subjectID hemi' (run from within
the 'surf' subdirectory).
When I add the left/right cortical volumes, I get a total that is different from what is output in
the 'aseg.stats' file, which in version 5.0 is noted to contain total surface-based GM volume.
(Cortex, CortexVol: Total cortical gray matter volume (based on surface-stream).
What are the correct GM and WM surface-based volumes?
Thanks. Jim
