This list may contain information from a number of different derivatives; _phasing_MIR_der_refln.der_id indicates to which derivative a given record corresponds. (A derivative in this context does not necessary equate with a data set; see the definition of the PHASING_MIR_DER dategory for a more thorough discussion of the meaning of derivative.) It is not necessary for the data items describing the measured value of F to appear in this list, as they will already have been given in the PHASING_SET_REFLN category. However, these items may also be listed here for completeness, if desired. ; _category.id phasing_MIR_der_refln _category.mandatory_code no loop_ _category_key.name '_phasing_MIR_der_refln.index_h' '_phasing_MIR_der_refln.index_k' '_phasing_MIR_der_refln.index_l' '_phasing_MIR_der_refln.der_id' '_phasing_MIR_der_refln.set_id' loop_ _category_group.id 'inclusive_group' 'phasing_group' loop_ _category_examples.detail _category_examples.case # -- ==================================================================== 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 ====================================================================
