Hi I'm running Phenix Version: 1.4 Release tag: 3 doing a refinement with experimental phase restraints (HL coefficients) Are the experimental phases now included in the map coefficients? If so, with what weight? Are there parameters affecting this? I'm asking because there is one region of the map where the experimental phased density is significantly different from the model (perhaps from non-isomorphism of the major derivative), and in the map from phenix.refine the electron density follows the model, whereas in refmac, which does generate phase-combined map coefficients, the map density follows the experimental phases. (probably I shouldn't be using this non-isomorphous derivative in the refinement, but that's a different question) Phil
