Hi Rex, the command phenix.superpose_ligands 1.pdb 2.pdb will do it. 1.pdb and 2.pdb are two PDB files containing the ligands. The output result will be in overlay_1_pdb_2_pdb.pdb file. The algorithm is based on graph matching, and it is good for ligand-sized molecules. The atom labels can

Dear Rex, if I understood corrctly what you are looking for you could also use Gerard Kleywegt's lsqman, where you can pick the atoms which you want to use for superpositioning. Tim On Fri, Sep 03, 2010 at 12:44:03PM +0100, Rex Palmer wrote: > This is not really protein crystallography but we ar
