Zero padding in Refinement

Hi,
When running homogenous refinement on the output particles and volume from an ab-initio reconstruction job, the following error pops up. I don’t understand the reason.

Traceback (most recent call last):
  File "cryosparc_worker/cryosparc_compute/run.py", line 84, in cryosparc_compute.run.main
  File "cryosparc_worker/cryosparc_compute/jobs/refine/newrun.py", line 188, in cryosparc_compute.jobs.refine.newrun.run_homo_refine
AssertionError: Particle zeropadding size (E-step) is not even

I would appreciate it if you can help me.
Thanks

@shekshaa What is the box size (in pixels) of the input particles?
