Hi Everybody,
I am using phenix-1.3b.
When i tried to use "Optimizing target weights" utility by typing following command line

phenix.refine data.hkl model.pdb optimize_wxc=true optimize_wxu=true


I got following error.

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>

TypeError: __init__() takes at least 5 non-keyword arguments (3 given)

May anybody tell me please how can i fix these errors??
