multi-body refinement

[ncoudray]

Hi,

I tried multi-body refinement and get the following error message:

=== Backtrace  ===

==================
ERROR: 
MetaDataTable::read: File MultiBody/job872/run_data.star does not exist

I am not sure if it is a bug or if I did something wrong and what are the consequences of this message. Also, this error message doesn't crash the job - It is still running and is now at iteration 1.

Best, Nicolas

It seems that relion_flex_analyse was executed before multi-body refinement finished. I don't know why. run_data.star is the output from refinement. As long as relion_refine_mpi is running, you don't have to worry. Once it is done, press Continue to run relion_flex_analyse again.

Thanks for the feedback - Maybe the reason is the same as for the logfile? (some synchronization bug that appears only on fast machines?)

I don't think so; we don't use & here.

This error is expected when the multibody refinement (relion_refine_mpi) fails. But relion_refine_mpi is running in your case... I don't know what is wrong.
