Error with keys during live

[dzyla]

I ran my first live session in v5.0.0 (also v5.0.1) and got this error during particle picking (Patch motion and CTF worked well):

Fail count: 2

Traceback (most recent call last):

KeyError: ‘particles’

Modifications to the standard live session are 2 workers per GPU and a Fourier crop of 0.5.

Best,

This issue occurs when the worker returns no particles. I believe it should be fixed to always return all the keys, so that even if there are no particles in the micrograph, no error occurs. The problem was that the minimum score threshold was set too high, preventing any particles from passing it.

Thanks @dzyla for this report. We think we have found the cause and plan to release a fix. For an immediate workaround, one can try re-running the session with the Enable Plotting in RTP Worker advanced parameter disabled.
