[phenixbb] Map after refinement

Hi Phenix developers/gurus,
I got a SAD structure, the experimental map (overall_best_denmod..mtz) from
Autosol looks great. I then built the model and used phenix.refine to refine
the model using the "exptl_fobs....mtz", which worked well as shown by the
lowered Rfree. However, the map from the refinement makes no sense at all,
totally featureless. Using the same refined model and mtz,
phenix.model_vs_data did make the right map. I have tried both phenix 1.5
and 1.6. Any clue?
Thanks,
