Dear AJ,

Both sbTIV and eTIV are trying to model the same thing, but sbTIV seems to be a slightly better approximation in some cases:

Either one is fine, in any case ;-)

Hi,

How does one normalize the data output from hypo_seg for the head size, with sbTIV or eTIV, which are a bit different from each other.

Many thanks

AJ
