Hello all,

I will greatly appreciate the help for the following:

I am getting the error "RuntimeError: min() argument is an empty array" (more details error message given below) while running phenix.refine. I am using PHENIX:  Version: 1.3 on  Platform: mac-intel-osx osx-10.5.7

My error message is as follows: 

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

Thanks in advance,
