Hi,

I am having trouble getting phenix to used segid's in reference model restraints when

my reference and target pdbs both don't use chain ID's.

phenix quits with this message:

*** Adding Reference Model Restraints ***
Sorry: chain ' ' in /home/path/removed/agnref2.pdb contains one or more errant TER cards.
Please remove and try again.

my definition file looks like this:

refinement {
   main {
     reference_model_restraints = True
   }
   reference_model {
     file = two.pdb
   }
}

refinement.reference_model.reference_group {
reference = segid A16S
selection = segid A16S
}

(above about 50 more times)

this was on versions 1.9-1692 , dev-2016 and dev-2056

any suggestions ?

thanks

jpd
