[MINC-users] Intracranial volume

[Andrew Janke]

Well I am sure that Louis would disagree here... ;)

He wrote a thing called BICCR (Brain Intra-Cranial Capacity Ratio) at
one stage and published a paper on it. I am not sure where the scripts
are to do it though!

Perhaps email Louis Collins directly and he can point you in the
direction of the code that he used to do it. Either that or the FSL
route shoudl work too.
