[phenixbb] dihedral error

[Simon Kolstoe]

phenix.refine keeps on stopping with the error:

AssertionError: Conflicting dihedral restraints:
   tor id: var_002
   1. definition from: residue: DRG, conformer A
   2. definition from: residue: DRG, conformer A
   atoms:
     " CB  DRG A 500 "
     " OG1 DRG A 500 "
     " PAL DRG A 500 "
     " OAF DRG A 500 "

It is for a phospho-threonine residue whose dictionary I made in  
PRODRG. I've tried all the different charge states of the phosphate  
however phenix gives the same error every time. Any ideas?

Thanks,

Simon
