Are the values you want not in the aseg.stats file? You can do it from individual ROIs, but you have to  use all of them, not just the ones you list

        External Email - Use Caution        

Dear Freesurfer Experts,


I want to generate global measures of cortical thickness and pial surface area analogous to using total cerebral volume as a global brain volume estimate.


In your opinion, would it be reasonable to generate these global thickness and surface area estimates from the following .aparc variables:


SurfArea.lh.Frontal
MeanThick.lh.Frontal
SurfArea.rh.Frontal
MeanThick.rh.Frontal
SurfArea.lh.Occipital
MeanThick.lh.Occipital
SurfArea.rh.Occipital
MeanThick.rh.Occipital
SurfArea.lh.Parietal
MeanThick.lh.Parietal
SurfArea.rh.Parietal
MeanThick.rh.Parietal
SurfArea.lh.Temporal
MeanThick.lh.Temporal
SurfArea.rh.Temporal
MeanThick.rh.Temporal

Regards,


Micah
