180198 (current)	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 7/10/94.	7109428.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.	7109428.cif
