130149 (current)	2015-01-27	cod/ (saulius@kolibris) Deriving Hall space group symbols for 12003 CIFs using the 'cif_filter --estimate-spacegroup' command.	1000054.cif
77586	2013-03-28	cod/cif/ (saulius@koala.ibt.lt) Merging mineral data updates (_chemical_name_mineral, _chemical_name_common, structural formulae) sent to me by T.D. in his e-mail. The merge was done by the command: for i in split/*.cif do ( B=$(basename $i); C=$(echo $B\|awk '{print "/home/saulius/struct/cod/cif/"substr($0,1,1)"/"substr($0,2,2)"/"substr($0,4,2)"/"$0}'); ( set -x; cif_merge --over \ _chemical_name_mineral,_chemical_name_structure_type,_chemical_name_common,_chemical_name_systematic,_chemical_formula_structural,_chemical_formula_sum \ $C $i ) \ \| cif_filter --add-cif-header $C \ \| sponge $C ) done in the working copy of the following repository: URL: svn+ssh://pitonas.ibt.lt/home/xray/svn-repositories/xyz-extraction/contributions Repository Root: svn+ssh://pitonas.ibt.lt/home/xray/svn-repositories/xyz-extraction Repository UUID: 9acf3947-1f02-0410-ae2a-984b57ad209b Revision: 2625 Node Kind: directory Schedule: normal Last Changed Author: saulius Last Changed Rev: 2625 Last Changed Date: 2013-03-28 15:13:00 +0200 (Thu, 28 Mar 2013)	1000054.cif
35911	2012-02-28	cif/ Reorganising ranges 1, 3, 5, 6 and 8 into a prefix-directory tree.	1000054.cif
966	2010-01-30	cif/ Adding _cod_database_code tags to all COD entries. Adding tag description to the cif_cod.dic dictionary so that COD entries can be validated.	1000054.cif
900	2009-11-21	cif/ Renaming data blocks of all COD CIFs so that they have COD number (taken from the COD file name) as their datablock number: find ? -name \.cif \ \| xargs \ perl \ -MFile::Basename \ -i \ -lpe 's/^data_([^\s])/"data_".basename($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.	1000054.cif
20	2008-01-26	Removing white space at the end of all lines from all COD CIF files: in the cod/cif/ directory: ff \*.cif \| xargs perl -i -pe 's/\s+\n$/\n/'	1000054.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/'	1000054.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	1000054.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.	1000054.cif
10	2008-01-04	BUG FIX: renaming all CIF files that had extension with all capital letters (.CIF) into files written in all lowercase (.cif). On Linux, where filenames are strictly cae-sensitive, the Web site engine would not find files that had .CIF extension (written in all caps).	1000054.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)	1000054.cif
