176729 (current)	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 1.	1100064.cif
130149	2015-01-27	cod/ (saulius@kolibris) Deriving Hall space group symbols for 12003 CIFs using the 'cif_filter --estimate-spacegroup' command.	1100064.cif
120071	2014-07-11	Adding DOIs to range 1 structures.	1100064.cif
112050	2014-04-29	cod/ (saulius@koala.ibt.lt) Marking 392 files as duplicates of the COD entries (with smaller COD IDs) that had identical title, cell constants and coordinates: mysql -u cod_reader cod -e ' select d1.file, d2.file from data as d1 join data as d2 on ( d1.title = d2.title or d1.title = substr(d2.title,1,length(d2.title)-1) or d2.title = substr(d1.title,1,length(d1.title)-1)) and d1.file < d2.file and d1.a = d2.a and d1.b = d2.b and d1.c = d2.c and d1.vol = d2.vol and (d1.calcformula = d2.calcformula or d1.calcformula is null or d2.calcformula is null) and d1.duplicateof is null and d2.duplicateof is null and d1.optimal is null and d2.optimal is null order by d1.file, d2.file' -NB \ \| xargs -i bash -c ' F1=$(echo {} \| awk "{print \$1}" \| codid2file); F2=$(echo {} \| awk "{print \$2}"\| codid2file); true echo === {} ===; if diff -q <(cif2ref $F1) <(cif2ref $F2) >& /dev/null; then CODID=$(echo {} \| awk "{print \$1}"); echo $CODID is the main entry for $F2; echo "_cod_duplicate_entry $CODID" >> $F2; fi' The localhost `cod` database's table `data` was loaded with the last night's COD `data` dump.	1100064.cif
35911	2012-02-28	cif/ Reorganising ranges 1, 3, 5, 6 and 8 into a prefix-directory tree.	1100064.cif
5312	2011-01-03	cif/ Adding files, updated with the 'cif_fix_enum' program and the cif_core.dic dictionary. The enumerator values were fixed, mostly incorrect case, but also some values that had extra underscores, dashes or spaces. Unfortunately, 22 had non-ASCII characters with the 8-th bit set, and these got incorrectly interpreted as latin1 characters and converted to their UTF8 equivalents by Perl. To fix the structures, however, they need to be redeposited from the original files with the new CIFParser/cif_filter version.	1100064.cif
966	2010-01-30	cif/ Adding _cod_database_code tags to all COD entries. Adding tag description to the cif_cod.dic dictionary so that COD entries can be validated.	1100064.cif
900	2009-11-21	cif/ Renaming data blocks of all COD CIFs so that they have COD number (taken from the COD file name) as their datablock number: find ? -name \.cif \ \| xargs \ perl \ -MFile::Basename \ -i \ -lpe 's/^data_([^\s])/"data_".basename($ARGV, ".cif")/e' After this change, 'cif2cod' will give correct keys in the generated table. Also, data block names are guaranteed to be distinct, so any subset of COD CIFs can be concatenated into one file without introducing ambiguity.	1100064.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/'	1100064.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	1100064.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.	1100064.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)	1100064.cif
