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):

Anyone has any idea what is happening?  Thanks.
