[phenixbb] phenix.refine issue

[Dennis Wolan]

I am having an issue with running a simple phenix.refine that I have  
never encountered before. I get a list of issues and the program quits  
with:

Traceback (most recent call last):
   File "/usr/local/phenix-1.4-3/phenix/phenix/command_line/ 
refine.py", line 9, in <module>
     command_line.run(command_name="phenix.refine", args=sys.argv[1:])

   File "/usr/local/phenix-1.4-3/iotbx/mtz/__init__.py", line 434, in  
as_miller_arrays
     and flex.min(column_group.sigmas()) > 0):
RuntimeError: min() argument is an empty array

I have no idea if the issue is with my pdb or mtz. I'm sure it's  
something very simple that I just am not identifying.

Thanks in advance,

Dennis
