Dear FS experts,

I need to crate a mask for whole white matter in the brain including the cerebellum. Also I need a mask for the whoe gray matter.

Can I binzarize ( i.e. use mri_binarize) and input the files:

wm.seg.mgz from the output of recon-all to create a a mask for global white matter

and the file ribbon.mgz the output of recon-all to create a a mask for global gray matter

Thank you for any advice!

Bests,
John Anderson
