Cannot convert float NaN to integer

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):
File "python-icebreaker-master/src/icebreaker/cli/ib_group.py", line 79, in

File "python-icebreaker-master/src/icebreaker/cli/ib_group.py", line 70, in main

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
