[3dem] ab initio reconstruction of multiple structures when each structure has a different point group symmetry

[Peter Doerschuk]

Dear 3DEM: For an engineering problem, I would like to do simultaneous ab initio reconstruction of two structures with different point group symmetries from a stack of unlabeled cryo EM images.  For instance, one structure has icosahedral symmetry, one structure has tetrahedral symmetry, and which images belong to which structure is not known.  I see e2refinemulti.html in EMAN2 but e2refinemulti.html is for refinement while I need ab initio model generation.  I would be very grateful for advice!  Thank you very much!  Best regards, Peter Doerschuk (pd83 at cornell.edu)
