hmmm, if you rerun does it complete?

Hi Bruce,
No error message, just runs forever and eventually breaks my SSH connection to the cloud
I'm running it on. But when I do "-make all" afterwards it starts a few steps
before mris_spheres, so I have to redo and often crashes again.
Thank you for your help!
Best,
Michael

Hi Michael
I think that is the last message that mris_sphere prints so I believe it has
finished. Does it exit with an error message or just keep running forever?

Dear Freesurfer Experts,
I’m fairly new to freesurfer, but have a set-up in which I have been
able to run many successful recon-all runs. One problem that I have
sometimes, maybe about 20% of the time, is that the run will freeze and crash
at this step:
mris_sphere -rusage
/mnt/freesurfer_subjs/SUBJECT_ID/touch/rusage.mris_sphere.lh.dat -seed
1234 ../surf/lh.inflated ../surf/lh.sphere
here’s the end of the logfile:
“== Number of threads available to mris_sphere for OpenMP = 2 ==

Does anyone have any ideas why this might be happening? Maybe this is
a computationally intensive step? If I run a few recon-alls
concurrently it almost always crashes at this step.
The command I run is: recon-all -all -openmp 2 -qcache
-nuintensitycor-3T -s SUBJECT_ID -sd /mnt/freesurfer_subjs/
Thank you so much for your help!
Best,
Michael
