Fitting of previously refined sub-models (e.g. segment A, segment B, segment CDEF from the upper arm) in ChimeraX as rigid bodies, then relaxing the model using ISOLDE before rigid body refinement in Phenix (rigid bodies selected: res. 95-472 of arm scaffold protein and dimers of arm segments A, B and C, dimer of arm segment D, dimer of arm segment E, dimer of arm segment F, trimer of tripod proteins, trimer of RBP1, trimer of RBP2, res. 489-752 of arm scaffold protein).
