External Email - Use Caution        

Thank you for the suggestion.
You were correct, removing the -parallel portion of the script resulted in successful longitudinal processing.

For documentation purposes on my end, any ideas why '-parallel' cannot be used for 'recon-all -long'? My lab has previously used '-parallel' to parallel-process cross-sectional data ('recon-all -all') successfully.

Thanks again for the insight!

You don't often get email from yhuang43@mgh.harvard.edu. Learn why this is important
  Caution: External email.

Your recon-all was run with ‘-parallel’ option. It is the multi-processing done at the recon-all level. There is no synchronization mechanism to ensure shared resources access/update.

 

Can you try to submit the recon-all without ‘-parallel’?

Hi FreeSurfer folks,

 

I'm attempting to use cloud computing (via Compute Canada) to run the FreeSurfer longitudinal pipeline on a batch of participants' images.

It seems like every participant exits at the same point in the pipeline: after mris_curvature.

Unfortunately, the error is extremely non-descript (recon-all -s subject exited with ERRORS"), making troubleshooting difficult.

 

Any advice or thoughts are greatly appreciated; recon-all.log and recon-all.error attached.
