phenix.autosol 11 Pb data=deriv.sca seq_file=seq.dat \ sites_file=deriv_hyss_consensus_model.pdbThis will carry out the usual structure solution process, but will read sites from deriv_hyss_consensus_model.pdb, try both hands, and carry on from there. If you know the hand of the substructure, you can fix it with have_hand=True.
