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?
