Hi all,


I issue the following command to pdb_atom_selection but I get 0 atoms selected at the end? 


$ phenix.pdb_atom_selection refine_to_submit.pdb "chain X and chain B"
refine_to_submit.pdb
  Monomer Library directory:
    "/usr/local/phenix-1.8-1069/chem_data/mon_lib"
  Total number of atoms: 3817
  Number of models: 1
  Model: ""
    Number of chains: 6
    Chain: "B"
      Number of atoms: 1800
      Number of conformers: 1
      Conformer: ""
        Number of residues, atoms: 84, 1800
          Classifications: {'RNA': 84}
          Modifications used: {'rna3p_pyr': 26, 'rna2p_pur': 5, 'rna3p_pur': 44, 'rna2p_pyr': 9}
          Link IDs: {'rna3p': 70, 'rna2p': 13}
    Chain: "X"
      Number of atoms: 1800
      Number of conformers: 1
      Conformer: ""
        Number of residues, atoms: 84, 1800
          Classifications: {'RNA': 84}
          Modifications used: {'rna3p_pyr': 26, 'rna2p_pur': 5, 'rna3p_pur': 44, 'rna2p_pyr': 9}

chain X and chain B
  0 atoms selected

Thanks!
