It excludes WM in cerebellum and brain stem. doug On 05/21/2013 10:31 AM, Ritobrato Datta wrote:

Hi All,

I am using freesurfer 5.1 and I want to compute the brain parenchymal fraction (GM+WM/GM+WM+ventricularCSF).

In aseg.stats, I get the whole GM vol and I can also get the total ventricular CSF by adding the vols of different ventricles.

But I am confused abt the terminology - CorticalWhiteMatterVol

is this volume the total white matter in the brain or does this exclude something ?

Please advise.

Best
