Hi Gonzalo
that's one of the reasons we use the surfaces for cortical morphometry, not the aseg.

Hi:
With some mprage images, I got differences in the volumetric segmentation (aseg) of the cortex and the white/gray surface... Why ?... I know that both methods are totally different... In the aseg I got some bad segmentation of the cortex, but it in the white/gray surface I got very better results...
Sincerely,
