Re: [Freesurfer] fscalc / mris_calc problem

Hi Fred -- I'm currently traveling and have limited internet connectivity. I'll be back at the office later in the week and will take a look then. In the meantime, has this ever worked for you previously? I know that older versions of 'mris_calc' were somewhat particular about filename lengths

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

2012-12-31 Thread Gonzalo Rojas Costa
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

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...
