Hi Dmitry, it sounds like you ran 2D classification with binned particles and would like to select some classes and use the unbinned particles downstream (perhaps another round of 2D to get โunbinnedโ 2D classes). You can select the classes of interest and input the selected particles to a new extract job to extract them without binning (fourier crop to box- blank). Once you have re-extracted without binning you can run another round of 2D or use for other jobs.
