If a Class P Filter job is queued up using ‘particles_all_classes’ from a not-yet-completed Heterogeneous Refinement (say, using only class 0), it will fail saying ‘particles.alignments_class_0’ is not connected. It used to work so it might be related to changing how the alignments are stored recently.
Hey @DanielAsarnow – apologies for the delayed response! Is the Hetero Refine job a clone of a pre-v4.5 job? When you build the Class Probability filter job, what do the low level inputs look like? (see below)
