Hi, In the past (phenix 1.13) I have been able to execute molprobity with the command line: ============== phenix.python /usr/local/phenix-1.14-3260/modules/cctbx_project/mmtbx/command_line/molprobity.py /home/roberto/sda/ScipionUserData/projects/TestMolprobityValidation2/Runs/000170_PhenixProtRunMolprobity/extra/5ni1.cif map_file_name=/home/roberto/sda/ScipionUserData/projects/TestMolprobityValidation2/Runs/000170_PhenixProtRunMolprobity/extra/molprobity.mrc d_min=2.200000 pickle=True pdb_interpretation.clash_guard.nonbonded_distance_threshold=None nproc=4 pdb_interpretation.clash_guard.nonbonded_distance_threshold=None ================== Unfortunately, for version 1.14 I get the error: ========================== Traceback (most recent call last): File "/usr/local/phenix-1.14-3260/modules/cctbx_project/mmtbx/command_line/molprobity.py", line 310, in <module> run(sys.argv[1:]) File "/usr/local/phenix-1.14-3260/modules/cctbx_project/mmtbx/command_line/molprobity.py", line 193, in run map_params=params) File "/usr/local/phenix-1.14-3260/modules/cctbx_project/mmtbx/validation/molprobity/__init__.py", line 216, in __init__ molprobity_map_params=map_params.input.maps) File "/usr/local/phenix-1.14-3260/modules/cctbx_project/mmtbx/validation/experimental.py", line 198, in __init__ from mmtbx.command_line.map_model_cc import get_fsc ImportError: No module named map_model_cc ============== That is, there is an error in the line "from mmtbx.command_line.map_model_cc import get_fsc" By the way, if I just run the command: ============== phenix.python /usr/local/phenix-1.14-3260/modules/cctbx_project/mmtbx/command_line/molprobity.py /home/roberto/sda/ScipionUserData/projects/TestMolprobityValidation2/Runs/000170_PhenixProtRunMolprobity/extra/5ni1.cif ================== the program is executed without any problem. What should I do in order to execute molprobity.py with the option map_file_name. best wishes Roberto
