The current version of the mmcif_pdbx dictionary at http://mmcif.pdb.org/dictionaries/mmcif_pdbx.dic/Index/index.html
defines _refln.pdbx_DELFWT _refln.pdbx_DELPHWT _refln.pdbx_FWT _refln.pdbx_PHWT as fields in which you can deposit coefficients from the computation of weighted Fo-Fc and 2Fo-Fc maps; this is marvellous, since previously it's been very unclear how you deposit maps. However, when I make an mmcif file with entries for these fields and pass it through the version of cif2mtz in ccp4-6.2.0, I get Line 77: data name "_refln.pdbx_DELFWT" not present in dictionary Line 78: data name "_refln.pdbx_FWT" not present in dictionary Line 79: data name "_refln.pdbx_DELPHWT" not present in dictionary Line 80: data name "_refln.pdbx_PHWT" not present in dictionary Is it possible to edit the dictionary? It appears to be supplied as lib/cif_mmdic.lib which is a binary file; presumably that's produced with some kind of compiler from some kind of source file, but I'm not sure how to start looking for the compiler and the source.
