2D Classification: ValueError: index is out of bounds for array

Troubleshooting

Hi, I’m also getting the same error here. 2D classification constantly gives error: File “cryosparc_master/cryosparc_compute/engine/newengine.py”, line 1619, in cryosparc_master.cryosparc_compute.engine.newengine.EngineThread.find_best_pose_shift_class
File “<array_function internals>”, line 5, in unravel_index
ValueError: index -4194304 is out of bounds for array with size 336. This is 2D jobs on Reference based Motion corrected particles. Any help is appreicated!

@hgxy15 We are not sure what is causing this issue. Another user linked a similar error to a faulty RAM module: Out of bounds error, 4.2.1CS, 2D, 2080TI - #3 by mulik52.

Hi @wtempel I was able to identify the problem following your previous suggestions. The error originated from a particle with NAN values. Thanks for the help

As of CryoSPARC v4.5, the error message when NaN particle values are encountered will be clearer (it will directly state that NaN values were encountered)
