| Revision | Date | Message | Files |
|---|---|---|---|
| 277836 (current) | 2022-09-14 | cif/ Added space group information derived from the space group operation list using the 'cif_filter' program. |
2203958.cif |
| 277835 | 2022-09-14 | cif/ Reordered data items using the 'cif_filter' program to ensure that future changes to the file result in a minimal number of modified lines. |
2203958.cif |
| 176774 | 2016-02-20 | cif/2/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/20. |
2203958.cif |
| 132410 | 2015-02-25 | cod/ (robertas@burundukas) Replaced zero-length value of the tag '_chemical_name_systematic' with '?'. codsql 'select file, chemname from data \ where length(chemname) = 0' -NB \ | perl -ne 'print $1."\n" if /\b(\d{7})\s*$/' \ | codid2file \ | xargs perl -0777 -i -pe 's/\b_chemical_name_systematic \K \s*? ( \n ; \s*? \n ; | '\'' \s* '\'' \s*? ) (?=\n) /" " x8 . "?"/ixmse' |
2203958.cif |
| 91933 | 2013-12-28 | cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs. |
2203958.cif |
| 26848 | 2011-09-28 | cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree. |
2203958.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. |
2203958.cif |
| 321 | 2008-03-30 | Changing the COD CIF files header (comments) in all files that were recently deposited from the IUCr autodownloaded sources to the text agreed with IUCr. |
2203958.cif |
| 101 | 2008-02-08 | Renaming the '_[local]_cod_original_file' tag into '_[local]_cod_data_source_file'. This reflects better the actual usage of the mentioned files -- they were used for data extraction, but not as originals for verbatim copying. |
2203958.cif |
| 87 | 2008-02-04 | Adding CIF files from ActaE2004-Issues-4-12/ (1465 files). |
