I have updated Freesurfer on all of the nodes from version 4.0.0 to version 4.0.2. Please let me know if you encounter any errors.
Note: It appears that Freesurfer is still crashing on node6. I have yet to figure out what is causing this, but in the mean time, you should avoid node6 when running Freesurfer jobs.
I'm thinking about updating Freesurfer to version 4.0.5 soon, maybe on Monday (Sept. 22). It'd be best if there were no Freesurfer jobs running when I do this, so unless it's a problem, please don't submit any new jobs that might still be running on Monday.
