[MINC-users] Intracranial volume

[Morgan Hough]

Hi there,

Which version of FSL are you using? You might check if you have betsurf 
available (its certainly in the latest stable). It will give you inner 
and outer skull and you can improve the estimate with a T2 volume if you 
have that available as well.

Cheers,

-Morgan
