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

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!
