Are you talking about outliers across subject? Or across region? I would just
take the FS-supplied value instead of averaging the regions.

Hi Bruce,
Is it also necessary to remove outliers (eg. 3 SD from the mean) for
Freesurfer structural measures of MRI images that have been visually

Hi Bruce,
Thanks for the prompt reply. It is my understanding that l_thickness,
r_thickness and estimated intracranial volume are accurately measured.
Would I still need to identify and remove outliers if visual inspection of
the images has not been do
