301853 (current)	2025-08-22	Add cross-references to PubChem compounds in COD range 7/10/ Each referenced PubChem compound corresponds to the full crystal structure.	7106577.cif
180169	2016-03-26	cif/7/10/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 7/10/65.	7106577.cif
130086	2015-01-23	cod/ (robertas@burundukas) The 'cif_fix_values' program was applied to CIFs that have generated the validation messages containing tag '_exptl_crystal_density_meas'. 16946 CIFs had a values that were perceived as 'not measured' and they were changed to '?'. The total of 17089 CIFs was changed. Those that were not corrected by 'cif_fix_values' were reformatted by the parser (e.g. a doi tag was moved to another place). The processing command was: mysql -u cod_reader -h www.crystallography.net cod -e \ 'select distinct codid from validation \ where message like \ "%tag%_exptl_crystal_density_meas'\''%"' -NB \ \| xargs -i sh -c 'cif_fix_values {} \ \| cif_filter --add-cif-header {} \ \| sponge {}'	7106577.cif
106525	2014-03-15	cif/ (saulius@koala.ibt.lt) Adding DOIs to those Chem. Comm. structure descriptions that did not have it before and that could be matched unambiguously. Unambiguously means: a) journal name is "like 'Chem%Com%'" in SQl parlour b) first author's last name is the same in COD and in PubMed b) publication year and first page are the same in COD and in PubMed database. The commands to change these files where: awk '{print $1, $2}' outputs/join-dois.tab \ \| xargs -i sh -c ' CODID=$(echo {} \| awk "{print \$1}"); DOI=$(echo {} \| awk "{print \$2}"); CODFILE=$(echo $CODID \| codid2file); if ! grep -q _journal_paper_doi $CODFILE; then ( set -x; echo _journal_paper_doi $DOI >> $CODFILE ); else echo $CODID already has DOI; fi' Some files that did not had new-line at the end had to be fixed afterwards (in the ~/struct/cod/cif/7 directory, a COD working copy): svn st \ \| awk '{print $2}' \ \| xargs cifparse -q 2> /dev/null \ \| awk -F"'" '{print $2}' \ \| xargs perl -i -pe 's/_journal_paper_doi/\n_journal_paper_doi/' The working copy containing 'outputs/join-dois.tab' was: Path: /home/saulius/struct/xyz-extraction/dois/chem-comm-refetched-from-pubmed URL: svn+ssh://pitonas.ibt.lt/home/xray/svn-repositories/xyz-extraction/dois/chem-comm-refetched-from-pubmed Repository Root: svn+ssh://pitonas.ibt.lt/home/xray/svn-repositories/xyz-extraction Repository UUID: 9acf3947-1f02-0410-ae2a-984b57ad209b Revision: 2871 Node Kind: directory Schedule: normal Last Changed Author: saulius Last Changed Rev: 2871 Last Changed Date: 2014-03-15 11:18:46 +0200 (Sat, 15 Mar 2014) Three conflicts in files 10/81/7108128.cif, 10/81/7108130.cif and 10/99/7109903.cif were resolved manually.	7106577.cif
35909	2012-02-26	cif/7/: reorganising range 7 into a prefix-directory tree.	7106577.cif
