yes. The surface lives in a continuum and cannot necessarily be represented on a descrete grid On Sun, 1 Oct 2017, Fereshte wrote: 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, 201

Hi FreeSurfer experts, To follow up on my early post, I am wondering if I use fwhm=15 to analyze area, mri_surfcluster reported that it cannot find fwhm31 in fsaverage/${hemi}/cortex/fwhm31/... is this normal? When I use fwhm=10, everything seems to be okay. Best, Daniel On Tue, Sep 26, 2017 a

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 On Mon, 2 Oct 2017, angel angel wrote: I see. By the way is aseg.mgz the segmentation after surfaces ? I mean if th

you can't get an accurate estimate of sulcal CSF from just a T1 as you can't distinguish it from other things that are dark, so we don't geenerate a label for it cheers Bruce On Sun, 1 Oct 2017, angel angel wrote: Dear FreeSurfer Experts, I'm so new to the FreeSurfer. I have seen the CSF segm

Dear FreeSurfer Experts, I'm so new to the FreeSurfer. I have seen the CSF segmentation which is inside the ventricles in aseg.mgz but i couldn't see the peripheral CSF (the csf outside of cortex). I'm wondering how can i have it or probably its label? Thank you! __
