Thanks for your reply! Would it be possible to get more details on the process
of how I might go about correcting these volumes myself? It would be ideal if I
had the volumes prior to entering it into my statistical model (and thus I’d
prefer not to use

factor in order to account for head size. I’m wondering whether the other
volumes given, e.g. TotalGray or lhCorticalWhiteMatter, have a
