| 264417 (current) | 2021-04-22 | cif/1/10/06/ Removed a trailing space from an author name in entry 1100666. |
1100666.cif |
| 264416 | 2021-04-22 | cif/1/10/06/ Updated bibliographic information in entry 1100666. |
1100666.cif |
| 176428 | 2016-02-13 | Replaced deprecated COD CIF data names with their more modern alternatives. The _cod_cif_authors_sg_Hall and _cod_cif_authors_sg_H-M data items were renamed to _cod_original_sg_symbol_Hall and _cod_cif_authors_sg_H-M respectively. |
1100666.cif |
| 175154 | 2016-01-27 | cif/1/10/ (antanas@kurmis) Updating bibliography for entries 100666, 100667, 100668, 100669, 100670. |
1100666.cif |
| 93983 | 2014-01-21 | cif/1/10/06/ Fixing author name syntax. |
1100666.cif |
| 35911 | 2012-02-28 | cif/ Reorganising ranges 1, 3, 5, 6 and 8 into a prefix-directory tree. |
1100666.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. |
1100666.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. |
1100666.cif |
| 853 | 2009-11-16 | cif/ Reconstructing spacegroup designators from the symmetry operators were possible. The comands used can be found in the log file reformat-spacegroups-2009.11.14.log committed with the current revision. Only lines that contained spacegroup designators were changed, and all files pass vcif test after the conversion. |
1100666.cif |
| 23 | 2008-01-27 | Removed characters with the high-bit set from all COD CIF files, using the following commands: ff \*.cif \ | xargs -n1 perl -ne 'print $ARGV,"\n" and last if /[\177-\377]/' \ | tee have-high-bit-chars.lst cat have-high-bit-chars.lst \ | xargs -t -n1 -iI sh -c 'iconv -f latin1 I \ | utf8-to-cif \ | perl -pe "s/€/\\\\/g" \ | fold -w 79 -s > I.tmp; mv I.tmp I' Afterwards, some file were corrected manually, to remove one remaining \177 character, and to fix single-quoted lines that became too long and were folded. |
1100666.cif |
| 19 | 2008-01-26 | Changing all end-of-line codes from DOS style to UNIX style in all COD CIF files, for more convenient processing: In the cod/cif/ directory: ff \*.cif | xargs perl -i -pe 's/\r\n/\n/' |
1100666.cif |
| 14 | 2008-01-14 | Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files. |
1100666.cif |
| 13 | 2008-01-13 | Setting the svn:keywords property to "Author Date Revision URL Id" for all CIF files in the cod/cif directory. |
1100666.cif |
| 1 | 2007-11-30 | Adding all .cif files from the COD, downloaded in a Cod.zip file on 2007.02.07 (and the same Cod.zip is downloadable today, on 2007.11.29) |
