OK, thx. It looks like that measure does exclude ventricles/csf, per the website.
BrainSegNotVent - same as BrainSeg without ventricles (lateral,
inferior lateral, 3rd, 4th, 5th), CSF, and choroid plexus

Along with normalizing for eTIV, we’d like to normalize regional cortical volumes for total brain/tisuse volume (TBV).
Is the output BrainSegNotVent in the aseg.sats basically equivalent to TBV?
