Grainy 2D averages

Hey all. I can’t get rid of a certain graininess in my averages. I have tried to change the reconstitution resolution but this didn’t change much.
Is it due to bad image quality in the first place or are there other parameters I could change in the 2D classification job?

Hi Dario, likely signal to noise.
see Streaky classes for some answers.

Thanks a lot, I will go and try the suggested answers.

Much much better. Looks like its overfitted though. But then again, the particles per class is super low.
