I mean if the holes and handles are corrected in the aseg.mgz. You mean sampling the surfaces into the volume may cause topological defects? On Sun, Oct 1, 2017 at 11:04 PM Bruce Fischl fischl@nmr.mgh.harvard.edu wrote:
hmmm, not exactly sure what you mean, but the aseg is corrected with the topologically corrected surfaces. Note that sampling them into the volume can change the topology though

I see. By the way is aseg.mgz the segmentation after surfaces ? I mean
if the topology correction is
considered. Thank you!

you can't get an accurate estimate of sulcal CSF from just a T1 asyou can't distinguish
it from other things that are dark, so we don't geenerate a labelfor it

inside the ventricles in aseg.mgz but i couldn't see the peripheral CSF (the csfoutside of cortex).
I'm wondering how can i have it or probably its label? Thank you!
