| 35909 | 2012-02-26 | cif/7/: reorganising range 7 into a prefix-directory tree. | 7008249.cif |
| 11752 | 2011-02-18 | cif/7/ Redepositing RSC CIFs that were formally processed with an old version of cif_fix_values script. |
7008249.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. |
7008249.cif |
| 1504 | 2010-09-08 | cif/7/ Adding data extracted from RSC 2005 and 2006 year publications. |
