Often we will start using blob picker in Live, then once we have a few decent 2D classes from the streaming job (not in template generation, just regular streaming 2D), we use these to re-pick using template picker and re-extract.
How are these newly re-extracted particles treated for the purposes of 2D? It seems like they are by default correlated with the existing 2D references, is this the case? Are the existing particles out of 2D automatically discarded when there is a change in extraction parameters?
The reason I ask is that often after doing this the streaming classes seem to degrade - but the picking is genuinely better, and indeed the classes improve markedly when I restart with a different number of classes (to force it to start from scratch).
