looks mostly right. For CSF there is a "CSF" label that should be included. For WM, you may or may not want to include brainstem.

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
