111965	2014-04-28	cif/ (saulius@koala.ibt.lt) Merging information from the recently deposited Chem. Comm. duplicates into the original files, and marking the new files as duplicated. The reason why the duplicates were overlooked was the changed publication year, and missing DOIs in the older entries. Since now DOIs are always recorded, this problem should not arise in the future. The command to update COD files was: grep '^7' cod-title-duplicates-single-year-diff.lst \ \| xargs -i sh -c ' OLDID=$(echo {}\|awk "{print \$1}"); MAIN=$(echo $OLDID \| codid2file); NEWID=$(echo {}\|awk "{print \$2}"); DUPL=$(echo $NEWID \| codid2file); echo === {} ===; sed "s/data_${NEWID}/data_${OLDID}/" ${DUPL} \ \| cif_merge \ --override-tag _journal_name_full,_journal_year \ ${MAIN} - \ \| cif_filter --add-cif-header ${MAIN} \ \| sponge ${MAIN}; echo "_cod_duplicate_entry $OLDID" >> ${DUPL}' The 'cod-title-duplicates-single-year-diff.lst' file was produced from the previous COD database version by the followinf command: mysql -NB -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 abs(cast(d2.year as signed)-cast(d1.year as signed)) = 1 and d1.duplicateof is null and d1.duplicateof is null and d1.year >= 1970' (The last 'd1.duplicateof is null' is actually a mistake, it should have been 'd2.duplicateof is null', but the result should at this point be the same...).	7108824.cif
