  Preparation for phenix.refine

    Ligand restraint generation using eLBOW, phenix.elbow
    

  Build ligand and use monomer library to name atoms : LHG
  Using monomer library entry LHG as template

  Attempting to download Chemical Components file for F6C
  Running eLBOW on F6C.cif

   Residue has metal at the centre of a coordination sphere. Using input
   geometry to generate restraints. Hydrogens may not be added.
