Replicating cryosparc live particle picks/ 2Ds during processing

Hi! I was running cryosparc live (v3.3.2) during collection and had some promising particle picks/ class averages. When I restart the processing in cryosparc v4.5.3, I am having trouble finding those same particle picks/ classes in the same dataset (even if I’m mimicking the same settings I used during live). Are there settings in 2D Class that i can try to change that are more likely to mimic how the classification works on live? I’ve tried to increase EM iterations and a few other things but nothing has worked so far. I’m trying to avoid re-copying the data.

I’d appreciate any ideas/help!! Thanks so much!

Hi @mhaile! Welcome to the forum!

The 2D Classification algorithm does differ slightly between Live and “regular” CryoSPARC (there’s some discussion of this here), but in general, we expect their performance to be similar.

Can you describe what differences you’re seeing between the two jobs? Or, if you want, I’d be happy to take a look at your Live and regular 2D classes and we may be able to figure out a way to get a successful result for you!
