Hi Renat,
That 3rd defect is fairly large – normally it would hang but it’s possible you’re running out of memory. If you can zip the subject and file drop it to us, we can take a look:

best,
Andrew

Subject: [Freesurfer] Freesurfer 7 crashes during mris_fix_topology
External Email - Use Caution
Dear all,
I have a subject whose Freesurfer processing crashes during topology fixing step. The last lines in `recon-all.log` are:
After retessellation of defect 2 (v0=22890), euler #=-15 (110444,329616,219157) : difference with theory (-18) = -3
CORRECTING DEFECT 3 (vertices=8808, convex hull=2020, v0=31369)

For the full `recon-all.log` and `recon-all.error` files please see the attached files.
I tried to follow the manual topology fixing instructions from
MailScanner
has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/TopologicalDefect_freeview,
but *.white and *.pial surface files are missing from `surf` directory. It only contains these files:
lh.defect_borders lh.defect_labels lh.orig.nofix lh.smoothwm.nofix rh.orig.nofix rh.smoothwm.nofix
lh.defect_chull lh.inflated.nofix lh.qsphere.nofix rh.inflated.nofix rh.qsphere.nofix
Which files can I use in place of white and pial surface files in order to look for WM segmentation defects?
Some additional information about the data:
- I am running Freesurfer 7.1
- overall, there are no gross errors in WM segmentation, although the subjects does have significant temporal lobe atrophy
- there are two images acquired at different times, and processing fails for both images
- interestingly, processing didnt crash with Freesurfer 6.
Thank you and have a great weekend,
Renat.
