Cannot convert float NaN to integer

Start with python-icebreaker/src/icebreaker/cli/ib_group.py and the icebreaker/ice_groups.py traceback location, using the attached STAR files to reproduce the failure. Compare the grouped_micrographs.star and selected particles.star inputs and trace which value becomes NaN before the integer conversion. Done means the input cause is understood and the job reports or handles it without this traceback.

Hi I run the test jobs to "flatten" and to "group" micrographs through relion. These jobs completed successfully. Now, I selected my particles in relion and I am trying to assign ice thickness coeficient. I use the ib_group.py, input mics from grouped_micrographs.star and selected particles.star without any parameter settings and single-threaded.

The job throws this error:

Traceback (most recent call last):

ice_groups.append(int(micro_now[y1][x1] * 10000))
ValueError: cannot convert float NaN to integer

What could be the reason? I tried converting group_micrographs.star file using relion_convert_star to match the format of the native particle.star. Files I used by default are attached.

Could you please take a lot, as I would really like to test the capacity of the IceBreaker.

Thank you
