301863 (current)	2025-08-22	Add cross-references to PubChem compounds in COD range 7/20/ Each referenced PubChem compound corresponds to the full crystal structure.	7204910.cif
202017	2017-10-14	cif/ Marking COD entries in range 7 that are known to be related to ChemSpider entries using the _cod_related_entry data loop.	7204910.cif
180380	2016-03-26	cif/7/20/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 7/20/49.	7204910.cif
134621	2015-04-02	The 'cif_fix_values' script with an option '--fix-only-weighting-scheme' and 'cif_filter' script were run over CIF files which included an incorrect value of the data item '_refine_ls_weighting_scheme'. Read the log for more details. There were more than 18k CIF files with values to modify. Usually these incorrect values include comment with formulas, but values of this data item must be an enumerator. The script creates new data item '_refine_ls_weighting_details' to store these comments with formulas, and writes the enumerator 'calc' as a value of data item '_refine_ls_weighting_scheme'. There exists some exceptions in the script.	7204910.cif
120443	2014-07-15	Adding 17924 DOIs guessed from source file names.	7204910.cif
35909	2012-02-26	cif/7/: reorganising range 7 into a prefix-directory tree.	7204910.cif
5312	2011-01-03	cif/ Adding files, updated with the 'cif_fix_enum' program and the cif_core.dic dictionary. The enumerator values were fixed, mostly incorrect case, but also some values that had extra underscores, dashes or spaces. Unfortunately, 22 had non-ASCII characters with the 8-th bit set, and these got incorrectly interpreted as latin1 characters and converted to their UTF8 equivalents by Perl. To fix the structures, however, they need to be redeposited from the original files with the new CIFParser/cif_filter version.	7204910.cif
3946	2010-12-16	../uploads/cif-deposit/cod/cif Adding structures of 7204910 via cif-deposit CGI script.	7204910.cif
