Hi,
We want to control for intracranial volume in our analyses but we would like verify the reliability and validity of the ICV volume reported in the aseg.stats file (I know the methods reported on the WIki - http://surfer.nmr.mgh.harvard.edu/fswiki/eTIV but haven't seen much in the way of a mask file we could look at). Is there an actual ICV mask file we can look at and load (and potentially edit)? Or, if not, is there an easy way to create an ICV mask?
Thank you,
