2D multi class select

Probably Oli thought of it 2 years ago… Request to Select2D with multiple outputs - especially with the development of “solve structures from complex mixtures” i.e. cryoID. Would be nice to presort 10 obviously distinct particles in 1 job (not just “views”).

alternatively I have resorted to using “excluded particles” and “excluded templates” as my inputs for 2D select and this whittles down the pool of classes as you bin them iteratively
