Dear John, Still I could not find the PDB subset cif for SF from mmCIF 0.9.0. > _phasing_MIR_refln.der_id . . . . . . . . . . . . . . 74 > _phasing_MIR_refln.F_calc . . . . . . . . . . . . . . 79 > _phasing_MIR_refln.F_calc_au . . . . . . . . . . . . . 85 > _phasing_MIR_refln.F_meas . . . . . . . . . . . . . . 91 99 104 > _phasing_MIR_refln.F_meas_au . . . . . . . . . . . . . 95 > _phasing_MIR_refln.F_meas_sigma . . . . . . . . . . . 98 > _phasing_MIR_refln.F_meas_sigma_au . . . . . . . . . . 103 > _phasing_MIR_refln.index_h . . . . . . . . . . . . . . 108 > _phasing_MIR_refln.index_k . . . . . . . . . . . . . . 112 > _phasing_MIR_refln.index_l . . . . . . . . . . . . . . 116 > _phasing_MIR_refln.phase_calc . . . . . . . . . . . . 120 In the mmCIF 0.9.0 save__phasing_MIR_der.id _item_description.description ; The value of _phasing_MIR_der.id must uniquely identify a record in the PHASING_MIR_DER list. Note that this item need not be a number; it can be any unique identifier. ; loop_ _item.name _item.category_id _item.mandatory_code '_phasing_MIR_der.id' phasing_MIR_der yes '_phasing_MIR_der_refln.der_id' phasing_MIR_der_refln yes '_phasing_MIR_der_shell.der_id' phasing_MIR_der_shell yes '_phasing_MIR_der_site.der_id' phasing_MIR_der_site yes loop_ _item_linked.child_name _item_linked.parent_name '_phasing_MIR_der_refln.der_id' '_phasing_MIR_der.id' '_phasing_MIR_der_shell.der_id' '_phasing_MIR_der.id' '_phasing_MIR_der_site.der_id' '_phasing_MIR_der.id' _item_type.code line loop_ _item_examples.case 'KAu(CN)2' 'K2HgI4_anom' 'K2HgI4_iso' Are you planning to include PDB's subset for MIR phasing data? What this means '_phasing_MIR_der_refln.der_id' phasing_MIR_der_refln yes regards, Jiang. -- ==================================================================== Jiansheng Jiang Ph.D. | Protein Data Bank | Phone: (516) 344-6388 Biology Department, Bldg 463 | Fax: (516) 344-5751 Brookhaven National Laboratory | mailto://jiang@bnl.gov Upton NY 11973-5000, USA | http://www.pdb.bnl.gov/~jiang ====================================================================
