Re: [Freesurfer] Overinclusion of brain volume during segmentation - Question

Thanks a lot!! I have a follow up question: We use the command asegstats2table to output the subcortical volumes (and other whole brain volumes) to table. If the aseg is incorrect, can we still believe those values? Thanks, Christina On Thu, Mar 20, 2014 at 1:27 PM, Bruce Fischl wrote: > H

Hi Christina if the aseg is incorrect but the surfaces are right, then you don't need to worry about it. This is the reason we typically use the surfaces instead of the aseg for things like brain volume/cortex modeling. cheers Bruce On Thu, 20 Mar 2014, Christina Chen wrote: Hi! If the co

Hi! If the cortical surface outlines are fine, but there is an overinclusion of brain volume during segmentation, how should I fix this? Can we calculate brain volume based on the cortical surface outlines -- if so, how? Thanks! Christina ___ Freesurfe
