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.

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
