That is what I would do. The FS WM volumes are computed using the surface, so it will be more accurate (and probably a little bigger)

Dear SAMSEG developers,

 

Is there an easy way/specific function to compute the total volumes (GM, WM and Total Brain) after the cross sectional processing pipeline has been run?

I currently add the volumes specified here: MorphometryStats - Free Surfer Wiki (harvard.edu)

However, adding the WM volumes (lhCerebralWhiteMatter + rhCerebralWhiteMatter + WM hypointensities) results in lower volumesthan  the volumes found with FreeSurfer.

 

Thank you very much in advance!

 

Best regards,

David
