| 175103 | 2016-01-27 | cif/ (antanas@kurmis) Adding full bibliography for entries 1100989, 100992, 1100995, 1100996, 1100998, 1101000, 1101001, 1101002, 1101004, 1101005, 1101007, 1101008, 1101009, 1101010, 1101011, 1101012, 1101013, 1101014. |
1100998.cif |
| 35911 | 2012-02-28 | cif/ Reorganising ranges 1, 3, 5, 6 and 8 into a prefix-directory tree. |
1100998.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. |
1100998.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. |
1100998.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/' |
1100998.cif |
| 14 | 2008-01-14 | Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files. |
1100998.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. |
1100998.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) |
