Hi Bruce,
No, I expect cerebellar volume to vary with diagnosis, but I want to account for the head size differences. This seemed to me the way to do that, but of course I am not an expert.
Best,
Marja

if you expect cerebellar volume to vary in an uninteresting way with head size (which I think you probably do)

Ok Thanks! Just to be sure, the eTIV would also make the cerebellar numbers
more informative right?

yes, you can just use those volumes, and no, including it as a regressor isn't the same as dividing by eTIV (although you can do that instead). cheers Bruce On Fri, 10 Jun 2016, Marja Caverlé wrote: Ok thanks Bruce. If I want to use these cerebellar white matter volumes, I assume I also need to use the eTIV as regressor right? (just like for the cerebral volumes? And maybe a stupid question, but can I use the eTIV as regressor by just dividing the structure volume by the eTIV?

I already did recon -all on all my subjects, but I cannot find any of these numbers in the .stats files. Am I just missing them, or does the recon all not do any cerebellar stuff?
