Dear all, I am writing a bash script for running phenix.phaser automatically on an ensemble of multiple pdbs. These pdbs have been superimposed by other tools before running phaser. The following is what I wrote for the ensemble part in params.eff file: ensemble { model_id = a1 coordinates { pdb = model1.pdb pdb = model2.pdb pdb = model3.pdb pdb = model4.pdb rmsd = None identity = 0.9 } It runs well. When it finished, I want to confirm that it really run MR on all four models or on a ensemble of these models. However in .log file, I found at the refinement part it shown me: ---------- REFINEMENT ---------- There is 1 solution to refine Refining solutions 0% 100% |==| DONE Configuring ensembles --------------------- PDB file # 1: model1.pdb This pdb file contains 1 models The (input) RmsD of this model with respect to the real structure is 0.8 **************************** Does this mean that phenix.phaser only run MR with the first model? Does it due to the way I wrote in my params.eff file? What would be the correct way? Many thanks! best, G
