Bases: pwem.protocols.protocol_3d.ProtRefine3D, relion.protocols.protocol_base.ProtRelionBase

Protocol to refine a 3D map using Relion.

Relion employs an empirical Bayesian approach to refinement of (multiple) 3D reconstructions or 2D class averages in electron cryo-microscopy (cryo-EM). Many parameters of a statistical model are learned from the data,which leads to objective and high-quality results.
