[Freesurfer] white/gray surface and volumetric segmentation (aseg) difference...
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...

Hi Gonzalo that's one of the reasons we use the surfaces for cortical morphometry, not the aseg. cheers Bruce On Mon, 31 Dec 2012, Gonzalo Rojas Costa wrote: Hi: With some mprage images, I got differences in the volumetric segmentation (aseg) of the cortex and the white/gray surface...
