Hi,

We've been encountering the following error when re-running 43 healthy
subjects through both the recon-all -all stream and through the
recon-all -long stream. The error seem to occur quite random with
regards to the subjects:

"
#...@# Cortical ribbon mask Tue Jun  2 03:09:13 CEST 2009
/work/220791.d/2039B.long.2039A/mri

--label_right_white 41 --label_right_ribbon 42 --save_ribbon
--save_distance 2039B.long.2039A

SUBJECTS_DIR is /work/220791.d

Segmentation fault

We've used Freesurfer v.4.1. The scans have previously been run in fs. 4.05.

After the error occurs, I've tried to rerun the subjects just through
this step. They usually complete the step after 1-2 subsequent reruns.
However, this is quite time consuming - any suggestions how to solve
this?

We use centOS4 64bit. I run the subjects on our computing cluster
which allocates 2,1 GB of memory for each subject. I've seen the error
addressed on the list earlier, but I couldn't find any obvious
solution.

Thanks!


Best regards
