The duplicates were indentified as entries havin identical DOIs, cell length parameters and formulae, unspecified or identical RI R-factors, and not already marked as duplicates or suboptimal structures. Furthermore, coordinates had to be identical when comparing results of cif2ref conversion: codsql \ 'select d1.file, d1.doi, d2.file, d2.doi from data as d1 join data as d2 on d1.doi = d2.doi where d1.a = d2.a and d1.b = d2.b and d1.c = d2.c and d1.duplicateof is null and d2.duplicateof is null and d1.optimal is null and d2.optimal is null and (d1.RI is null or d2.RI is null or d1.RI = d2.RI) and d1.file > d2.file and (d1.formula = d2.formula or d1.calcformula = d2.calcformula)' \ -NB \ \| awk '{print $1, $3}' \ \| xargs codid2file \ \| xargs -n2 \ \| xargs -i bash -c ' \ CIF1=$(echo {} \| awk "{print \$1}"); \ CIF2=$(echo {} \| awk "{print \$2}"); \ echo -e "\n=== {} ==="; \ diff -bw -u <(cif2ref $CIF1) <(cif2ref $CIF2)' \ \| perl -00 -ne 'print unless /^(-\|\+)/m' \ \| grep . > ~/duplicates-2014-10-05.lst The resulting '~/duplicates-2014-10-05.lst' was post-processed as follows: awk '{print $2, $3}' duplicates-2014-10-05.lst \ \| xargs -i bash -c ' \ ID2=$(basename $(echo {} \| awk "{print \$2}") .cif); \ CIF1=$(echo {} \| awk "{print \$1}"); \ set -x; echo _cod_duplicate_entry $ID2 >> $CIF1' Structures from one powder diffraction paper were reverted: svn revert /home/saulius/struct/cod/cif/4/12/19/412199[567].cif And two files with more than one duplicate identified were fixed by hand: emacs -nw /home/saulius/struct/cod/cif/7/05/43/7054322.cif emacs -nw /home/saulius/struct/cod/cif/7/05/43/7054325.cif	4506660.cif
