I see. By the way is aseg.mgz the segmentation after surfaces ? I mean if the topology correction is considered. <div>Thank you!<br><br>On Sunday, October 1, 2017, Bruce Fischl &lt;<a href="mailto:fischl@nmr.mgh.harvard.edu">fischl@nmr.mgh.harvard.edu</a>&gt; wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">you can&#39;t get an accurate estimate of sulcal CSF from just a T1 as you can&#39;t distinguish it from other things that are dark, so we don&#39;t geenerate a label for it<br>

Dear FreeSurfer Experts,<br>
I&#39;m so new to the FreeSurfer. I have seen the CSF segmentation which is inside the ventricles in<br>
aseg.mgz  but i couldn&#39;t see the peripheral CSF (the csf outside of cortex). I&#39;m wondering how can i<br>
have it or probably its label?  <br>
Thank you! <br>
