usually we use eTIV for volume and surface area but not for thickness

Hi Professor,

I ran three steps of "recon-all" and get the cortical thickness, surfarea, GrayVol in lh.aparc.stats and subcotical volume in aseg.stats. If I want to use SPSS software for statistics， should I use eTIV as a covariate for everyone? Thank you very much.

Sincerely, Zheng
