Hi, I was using phenix.refine from the latest cci apps bundle to do tls +individual_sites+individual_adp refinement. The program crashed with the following error message. ----------Target weights (before refinement)---------- Traceback (most recent call last): File "/nfs/home/jzhu/cci_apps_sources/phenix/phenix/command_line/ refine.py", line 5, in <module> command_line.run(command_name="phenix.refine", args=sys.argv[1:]) File "/nfs/home/jzhu/cci_apps_sources/phenix/phenix/refinement/ command_line.py", line 75, in run call_back_after_monitor_collect=call_back_after_monitor_collect) File "/nfs/home/jzhu/cci_apps_sources/phenix/phenix/refinement/ driver.py", line 1108, in run log = log) File "/nfs/home/jzhu/cci_apps_sources/phenix/phenix/refinement/ strategies.py", line 245, in refinement_machine log = log) File "/nfs/home/jzhu/cci_apps_sources/phenix/phenix/refinement/ weight_xray_chem.py", line 222, in __init__ compute_gradients = True) File "/nfs/home/jzhu/cci_apps_sources/mmtbx/mmtbx/restraints.py", line 144, in energies_adp_aniso xray_structure = xray_structure, File "/nfs/home/jzhu/cci_apps_sources/cctbx/cctbx/adp_restraints/ __init__.py", line 109, in __init__ self.check_flags(fl_i) File "/nfs/home/jzhu/cci_apps_sources/cctbx/cctbx/adp_restraints/ __init__.py", line 177, in check_flags assert not fl.use_u_aniso() AssertionError Anyone has any idea what is happening?
