Hello,

I want to calculate the Grey matter, white matter and  CSF  volumes.

The total gray matter volume is already in the ASEG file.

Then
I add up following volumes for ventricular CSF: Left Lateral Ventricle + Left Inferior Lateral Ventricle + Right lateral Ventricle  + Right Inf Lateral Ventricle + 3rd Ventricle + 4th Ventricle + 5th Ventricle  + Right choroids plexus + left choroids plexus. 

also,

 I add up following volumes for white matter volume:  CorticalWhiteMatterVol +Left-Cerebellum-White-Matter + Right-Cerebellum-White-Matter.

Are these right?

Thanks,

Jinsong
