Dear all,

I am refining a protein structure using phenix.refine, when i tried to use

optimize_wxc, optimize_wxu

It always crashes and gives following error. May anybody can explain what is the problem??

  

Traceback (most recent call last):
  File "/public/xtal/phenix/phenix-1.3b/phenix-1.3b/phenix/phenix/command_line/refine.py", line 5, in <module>
    command_line.run(command_name="phenix.refine", args=sys.argv[1:])
