Hi Christina
we don't correct any volumes for head size - we just provide the
information for you to do it yourself. I think including it as a
regressor is more common than dividing it out, but perhaps others can
comment.

Hello,
I have a question regarding volume-correction for the morphometry stats
obtained via recon-all. I’ve noted that eTIV is derived using the atlas
scaling factor in order to account for head size. I’m wondering whether the
other volumes given, e.g. TotalGray or lhCorticalWhiteMatter, have also been
corrected for head size? If not, is there a recommended method in which to
do so so that regional volumes can be compared between participants?
Many thanks for your help!
Best,
Christina
