Hi Pavel, I ran phenix.refine to produce a kicked map after deleting my ligand (to get an omit map). I got an error message. Sorry: Duplicate mtz_label_amplitudes:2FOFCWT Here is part of my .def file: How should I change it? map { mtz_label_amplitudes = None mtz_label_phases = None likelihood_weighted = None obs_factor = None calc_factor = None kicked = False fill_missing_f_obs_with_weighted_f_model = True } map { mtz_label_amplitudes = "2FOFCWT" mtz_label_phases = "PH2FOFCWT" likelihood_weighted = True obs_factor = 2 calc_factor = 1 kicked = True fill_missing_f_obs_with_weighted_f_model = True } map { mtz_label_amplitudes = "FOFCWT" mtz_label_phases = "PHFOFCWT" likelihood_weighted = True obs_factor = 1 calc_factor = 1 kicked = True fill_missing_f_obs_with_weighted_f_model = False } map { mtz_label_amplitudes = "2FOFCWT_no_fill" mtz_label_phases = "PH2FOFCWT_no_fill" likelihood_weighted = True obs_factor = 2 calc_factor = 1 kicked = False fill_missing_f_obs_with_weighted_f_model = False }
