|---|---|---|---|
| 288533 (current) | 2023-12-24 | Changed data name '_commputing_cell_refinement' to '_computing_cell_refinement' in entries 4024870, 4069541. |
4024870.cif |
| 288193 | 2023-12-08 | cod/ Corrected misspelt data names in multiple entries using the 'cif_correct_tags' program and a data names replacement file from cod-tools revision 9828. This change affected only the misspelt variants of the '_exptl_absorpt_process_details' data name. |
4024870.cif |
| 201982 | 2017-10-13 | cif/ Marking COD entries in range 4 that are known to be related to ChemSpider entries using the _cod_related_entry data loop. |
4024870.cif |
| 178427 | 2016-03-21 | cif/4/02/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 4/02/48. |
4024870.cif |
| 120074 | 2014-07-11 | Adding DOIs to range 4/02 structures. | 4024870.cif |
| 34330 | 2012-02-24 | cif/4/ Reorganising CIF range 4 into a prefix tree. |
4024870.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. |
4024870.cif |
| 966 | 2010-01-30 | cif/ Adding _cod_database_code tags to all COD entries. Adding tag description to the cif_cod.dic dictionary so that COD entries can be validated. |
4024870.cif |
| 948 | 2010-01-19 | cif/ Adding CIFs for the Acta-Cryst-B-2009_06/ Acta-Cryst-C-2009_12/ Acta-Cryst-E-2009_12/ J-Appl-Cryst-2009_06/ J-Org-Chem-2009/ deposition. |
