| 202017 (current) | 2017-10-14 | cif/ Marking COD entries in range 7 that are known to be related to ChemSpider entries using the _cod_related_entry data loop. |
7150170.cif |
| 176453 | 2016-02-16 | cif/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in range 7. |
7150170.cif |
| 120443 | 2014-07-15 | Adding 17924 DOIs guessed from source file names. | 7150170.cif |
| 35909 | 2012-02-26 | cif/7/: reorganising range 7 into a prefix-directory tree. | 7150170.cif |
| 1650 | 2010-10-21 | cif/{1,7}/ Restoring CIF headers in the recently redeposited RSC-originating CIFs. |
7150170.cif |
| 1648 | 2010-10-21 | cif/7/, cif/1/ Redepositing files from the 2005-RSC processing that were unambiguously identified by the cod_numbers program. Two files in COD were found truncated, and one has coordinates published in a journal that differ slightly from the COD entry; also the journal name is different -- most probably, the structure was update during publication. I assume however that the currently deposited structures are better description of the publisted research results, and thus overwrite the differing files. The command was: ( set -x; pwd; for i in */outputs/numbers.lst; \ do ( cd $(dirname $(dirname $i)); \ awk '{if($(NF-1)==1)print $NF,$(NF-2)}' outputs/numbers.lst \ | while read -a line; \ do \ L=$(echo ${line[1]} \ | awk '{print substr($0,0,1)}'); \ NEW=${line[0]}; \ OLD=~/struct/cod/cif/$L/${line[1]}.cif; \ cif_filter --renumber --start-data ${line[1]} \ $NEW --add-cif-header $OLD > $OLD; \ done ) \ done ) \ 2>&1 | tee ~/struct/cod/cif/redeposit-2005-RSC.log File 7/7150115.cif was in addition corrected manually (some s.d. values table were specified in an incorrect format). |
7150170.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. |
7150170.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. |
7150170.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/' |
7150170.cif |
| 14 | 2008-01-14 | Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files. |
7150170.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. |
7150170.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) |
