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)	1011053.cif

20519	2011-06-11	smi/* and cif/* Adding SMILES for all structures with nel=1 in the mysql entries, supossed to be pure elements. For most of them, just the element symbol remains since SMILES strings and substructure search makes no sense for compact packed structures. Only for molecularly defined substances (for example cyclosulphur moieties) a proper SMILES string has been defined. This does not add too much funcionality to substructure search but flags a large number of structures as "SMILES done". Some of them were found to be not pure elements (carbides, boranes, hydrocarbons) but were added anyway. CIF files and SQL entries have been fixed for these as well as for other with obviously wrong formulas.	1011053.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.	1011053.cif
720	2009-05-13	cod/cif/: Adding loop_ token in front of the _publ_author_name tag in all COD entries where _publ_author_name was not in a loop (this tag is loop-mandatory).	1011053.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/'	1011053.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)	1011053.cif
