Hi Bruce and Louis,
Thank you for the suggestions. I will try them out.
Just fyi. For our dataset this error is very rare. So far it occured only in 1 out of 525+ scans processed with FS 5.1.
Thank you, Mehul

Hi Mehul, Alternatively you can try rerunning the skullstrip step, sometimes this works as well.
recon-all -skullstrip -autorecon2 -autorecon3 -s [SubjID]

Hi Mehul
this is a bug in the topology correction that we haven't been able to track down, mainly because the person who wrote this piece is long gone. If you edit the wm to remove a defect it usually goes away

Hi Folks
I am using Freesurfer 5.1 and I get the following error: "ERROR: _FindFacePath: could not find path!"
Is this is a memory related issue ? The same case went through smoothly with Freesurfer 5.0. Also I have not seen this error over a large number of subjects and I thought it might be system related, but even when I re-run it, I get the same error.
From the recon-all.error file, the last command is "mris_topo_fixer -mgz -warnings -seed 1234 ms0709_01 rh"
Here is a small snippet from the recon-all.log file (just before the error)

you probably ran out of memory. That's a giant defect so something is badly wrong. Check to make sure that the hemis are separated and that the skull and cerebellum aren't attached BruceOn Wed, 26 Oct 2011, Sindhuja Tirumalai Govindarajan wrote:
Hi all,
I got the following error while running recon-all on a patient

Kindly let me know how to proceed.
Thanks!
