Rigid.inp in CNS

[Matthew Meyer]

Dear expert refiners,
    I have a dimer that I would like to refine as 2 separate rigid
bodies.
In rigid.inp, there is an atom selection section.
 What should I use for...   atom_select=(known and not hydrogen)
                                            group_1=( ? )
                                            group_2=( ? )
I've tried atom#s separated by a <space>   (1 1061) or a dash (1-1061)
or residue #s w/ chain ID (A5-A144)

or should I run rigid.inp twice?
(once for each monomer - on separate pdb files)

Thanks in advance,
