Dear all, I tried to use the phenix.model_idealization code of phenix (in command line) following the syntax suggested inhttps://phenix-online.org/documentation/reference/model_idealization.html phenix.model_idealization xxxx.pdb But the code stops on the error : Traceback (most recent call last): File "/Applications/phenix-1.20.1-4487/build/../modules/cctbx_project/mmtbx/command_line/model_idealization.py", line 1118, in <module> run(sys.argv[1:]) File "/Applications/phenix-1.20.1-4487/build/../modules/cctbx_project/mmtbx/command_line/model_idealization.py", line 1106, in run mi_object.run() File "/Applications/phenix-1.20.1-4487/build/../modules/cctbx_project/mmtbx/command_line/model_idealization.py", line 548, in run self._setup_model_h() File "/Applications/phenix-1.20.1-4487/build/../modules/cctbx_project/mmtbx/command_line/model_idealization.py", line 478, in _setup_model_h params_h.pdb_interpretation = self.model._pdb_interpretation_params.pdb_interpretation AttributeError: 'NoneType' object has no attribute 'pdb_interpretation' Thanks in advance for any suggestion to solve this.
