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.	1008774.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.	1008774.cif
35911	2012-02-28	cif/ Reorganising ranges 1, 3, 5, 6 and 8 into a prefix-directory tree.	1008774.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.	1008774.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.	1008774.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/'	1008774.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	1008774.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.	1008774.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)	1008774.cif
