What surface feature are you exvaluating? If thickness, then don't do
normalization by eTIV or surface area or anything else

I am building a brain age model from the stats extracted with FreeSurfer. I
tested my model normalizing volumes by eTIV, which I think is the
recommended, and surfaces by WM total surface. For surfaces, I haven't
found any
