There is nothing more you need to do. With --etiv, asegstats2table will divide by the eTIV (and multiply by something like 100k to make the values reasonable). At that point it is corrected. You could also regress against eTIV rather than dividing by it. I don't know which one is better.

Thank you Douglas for the answer. Could you be more explicit?
So, once you have the aseg.stats you need to run which command with --etiv-only?

It is not done. If you are running asegstats2table, you can have it perform the correction by adding --etiv to the command line

Hi,

Does the asegs.stats produced by recon_all have the volume estimates of subcortical structures adjusted by the eTIV?
I want to understand the effect of sex in the segmented structures. Should normalize the volumes of aseg.stats (Vol/eTIV) or is already done in recon_all?
Thank you!
