Our lab has been using Freesurfer 5.3 for it's ongoing longitudinal study. I attempted to quality check one of our brains using tkmedit - I usually don't have any issues following our pipeline or running the tool. This time I received this message:

ERROR: A segfault has occurred. This is not your fault,

: but is most likely an unrecoverable error and has

: made the program unstable.

: Please send the contents of the file .xdebug_tkmedit

: that should be in this directory to freesurfer@nmr.mgh.harvard.edu

: Now exiting...

I'm not sure where the xdebug file is located - it isn't anywhere in our Freesurfer directory in the server. Where can I find this file, and how can I fix this error? I've tried trouble shooting with some solutions I've seen in the archive. We have checked permissions, I use a PC - not a mac, and I have checked the main freesurfer directories as well as the directories associated with the brain I want to check. I have also tried to open other brains in the viewer resulting in the same error message. Is there a fix for this - ideally, one that doesn't require switching Freesurfer versions?
