I usually just divide the volume by the eTIV (you can do this in
asegstats2table with the --etiv flag). Some people will use it as a
nuisance regressor in the GLM

I hope you can help me with this point
I extracted the measures in 'aseg.stats', 'lh.aparc.stats',and
'rh.aparc.stats'. Now I want to use these measures as input data for
my model. However, I read that we need to normalize this data using
eTIV. Can you tell me how?
