Hi Martin

a defect that large means that something big went wrong (skull or dura attached, etc...). Try looking at the ?h.orig.nofix and/or the ?h.inflated.nofix surfaces with the ?h.defect_labels overlayed to find defect 9

Dear FreeSurfer team,

 

For a case report I’m running recon-all on a patient with a giant arachnoid 
cyst in the left
hemisphere. It gets stuck at this point (last message):

CORRECTING DEFECT 9 (vertices=21935, convex hull=1992, v0=31849)

XL defect detected...

It is stuck here since a whole day now, so I’m not expecting it to advance…

Following this post: 
https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg48891.html I
looked at the wm.mgz, but did not find huge errors.

Do you have any ideas what the problem might be or what I can do to work around 
it?

 

Thanks,

Martin
