Hi all, Using previous versions of FreeSurfer, we have used the eTIV as a covariate for our volumetric analyses. We have been using the eTIV numbers from 5.1.0 for new studies. What would you recommend using for subjects who have been run with 5.1.0? Can you make the template available publicly, or would it be legitimate to take the eTIV from 5.0 and the aparc stats from 5.1.0?
