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: https://surfer.nmr.mgh.harvard.edu/fswiki/sbTIV
Either one is fine, in any case ;-)

External Email - Use Caution
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 _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edumailto:Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
