Hi, I am trying to use kick map to remove model bias with the following script phenix.refine MR.1_refine_data.mtz MR.1_refine_001_refine_001.pdb output.prefix=refine-090828a simulated_annealing=True simulated_annealing.start_temperature=8000 strategy=individual_sites refine.params However, the program says: Sorry: Unknown file format: refine.params I do not understand why the format of refine.params cannot be read, which has the following contents. Does anyone know why? refinement { electron_density_maps { 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=True } }
