Hello Freesurfer experts,
I am currently doing some TBM analysis and to compute whole brain atrophy I consider all the structures except ventricles and CSF from aseg.mgz in my definition. Should I also include the cortex definition from aparc+aseg? If yes, should I then use aparc+aseg or aparc.a2009s+aseg segmentation file?
Any help will be greatly appreciated.
