Ab initio het recon fails to start, error in mrc.py

Troubleshooting

Hi guys,

One of my ab initio heterogeneous reconstruction jobs failed to start. This is the error that gets spit back at me. Can anyone help troubleshoot?

Traceback (most recent call last):
File “/mnt/Data_01/cryosparc/cryosparc-compute/sparcjob.py”, line 188, in
dataset = dataio.dataset_factory(current_dataset_params, do_cache=current_experiment_params.get(‘do_cache’, True))
