Thank you Bruce,
So, if I want to report the volume of the Corpus Callosum, I should add up the volumes of CC_Posterior, CC_Mid_Posterior, CC_Central, CC_Mid_Anterior, CC_Anterior only. The ctx-?h-corpuscalosum/wm-?h-corpuscallosum is just useless and better to remove them from wmparc.mgz since they corrupted the wmparc volume. The aseg.mgz is right one to look at Corpus Callosum area. Am I right?

you're probably right. We used to segement the cc on the surface, but this wasn't nearly as accurate as in the volume, which replaced it.

The Freesurfer 4.3 segments the cc into 5 parts. But the wmparc.mgz has both 5 parts along with ctx-?h-corpuscallosum/ wm-?h-corpuscallosum. I think they should not co-exist. Maybe I¹m wrong.
