| 291269 (current) | 2024-04-18 | cif/9: Inserting Z values for entries in the 9 range |
9000253.cif |
| 176725 | 2016-02-18 | cif/ (antanas@echidna.ibt.lt) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in range 9. |
9000253.cif |
| 35913 | 2012-02-28 | cif/9/ Reorganising range 9 into a prefix-directory tree. Range 9 is the last range to be reorganised. |
9000253.cif |
| 1071 | 2010-04-10 | cif/9/ Updating COD entries from AMCSD, processed in the AMCSD-resynchronisation-2009.06.24/ directory. Entries are updated if they could be unambiguously mapped to a unique COD number by automatic search scripts in AMCSD-resynchronisation-2009.06.24/. |
9000253.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. |
9000253.cif |
| 255 | 2008-03-10 | Redepositing all AMCSD (9*series) COD CIF files. This redeposition regenerates AMCSD (9* series) files, 10011 entries total, from the original source CIF file cifdata.cif found on the CD received from Armel. Most importantly, the truncated formulas seem to be corrected. The files are not folded, i.e. they have lines longer than 80 characters (conforming CIF 1.1 specification, but not CIF 1.0 specification), and are otherwise syntactically correct. Some missing coordinates were fixed manually, restoring them from the AMCSD site, and non-ASCII symbols were fixed automatically during filtering. After the redeposition, the cifs-with-errors.lst was regenerated using the following command: find -name \*.cif \ | xargs -n1 -iI sh -c 'vcif -l 2048 I || echo I' \ | grep -vE 'CIF|ERR' \ | sort > cifs-with-errors.lst & |
9000253.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/' |
9000253.cif |
| 14 | 2008-01-14 | Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files. |
9000253.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. |
9000253.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) |
