ZeroDivisionError: float division by zero in local refinement

Local Refinement
1

Greeting there,

I am running the local refinement but come across error as below. I searched previous posts and find some posts mentioned same error in different type of job.
How could I debug to run the local refinement?

Thanks in advance,
Yanhe

Hi Yanhe,

Please can you post

  • a screenshot of the job’s inputs
  • non-default job parameters

Hi Wolfram,

I have it solved by changing the mask used in the job running.
I am a cryoET guy, and always use Matlab for mask generation, I turn to tutorial by cryoSPARC and works now.
Anyway, thanks a lot.

Could you please answer my another post about NU refinement? I thought it is because of the box size problem, am I correct?

Thanks and best,
Yanhe
