Hi Francis,
Also it's not desirable to create a _refine_data.mtz as it's unclear where the experimental phase labels came from the first place. Suppose I'm doing iterative rounds of MRSAD (with updated models during model building), I may have several AutoSol directories containing MRSAD runs for updated models.
How am I going to know where the HL's in *_refine_data.mtz came from? (grepping .def files?)
It would be easier if the .def's contained the full paths of the original .mtz files and not a phenix combined data file. I may have my original reflections in one mtz, an R-free set in another, experimental phases in another, etc.
