282068	2023-03-26	cod/ (saulius@tasmanijos-velnias) Adding the '_cod_related_entry_...' loop to those COD AMCSD entries that lacked it, and adding the related AMCSD database ID to this loop.	9012135.cif
282053	2023-03-24	cod/ (saulius@tasmanijos-velnias) Updating the existing COD records from the recent AMCSD downloads: - Adding AMCSD IDs to those COD records that exacly matched the AMCSD structures (comparing unit cells, space groups, coordinates and measurement conditions) but did not yet have the AMCSD ID; - Adding new mineral names, compound sources, measurement conditions (when those were missing) and other informations from the AMCSD CIFs.	9012135.cif

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)	9012135.cif

893	2009-11-20	cif/ Generating _diffrn_ambient_temperature and _diffrn_ambient_pressure tags from the CIF file comments like "T = 100K" (using the 975 revision of cif_create_AMCSD_pressure_temp_tags). Mostly, series 9 CIFs (obtained AMCSD) have such comments. Only files that did not had these tags originally were changed. The tags were generated using the following command: ( \ set -x; \ find $(/bin/ls -rd ?) -name \*.cif \ \| xargs -n1 -iX \ bash -c 'awk "/^#/,/^data_/{print}/^data_/{exit}" X \ \| grep -v "^data_" > tmp-$$; \ cif_create_AMCSD_pressure_temp_tags X >> tmp-$$; \ if (grep -q _diffrn_ambient_temperature tmp-$$ >& /dev/null && \ ! grep -q _diffrn_ambient_temperature X >& /dev/null) \|\| \ (grep -q _diffrn_ambient_pressure tmp-$$ >& /dev/null && \ ! grep -q _diffrn_ambient_pressure X >& /dev/null); \ then \ mv -v tmp-$$ X; \ fi; \ rm -f tmp-$$' \ ) >& make-temp-pressure-tags.log After this, the modified files were checked using 'vcif': svn st \| grep ^M \| awk '{print $NF}' \| xargs -n1 vcif -l 2048 It was checked that for the other tags, only tag order and value formatting has changed in the modifed files, if at all: ( \ set -x; \ svn st ? \ \| awk '/^M/{print $NF}' \ \| sort \ \| xargs -n1 -iX \ bash -c 'echo -e "\n"=== X ===; \ diff -b \ <(svn cat X \| sort) \ <(sort X)' \ ) 2>&1 \| tee diff-sorted.log tdbgrep === diff-sorted.log \ \| grep -v ^=== \ \| grep -v '^> _diffrn_' \ \| grep . \ \| grep -vE '^[0-9]+a[0-9]+' \ \| less and the changed files were validated against the cif_core.dic (thus checking, among others checks, that the values of the inserted tags have correct types): ( \ set -x; \ svn st ? \ \| awk '/^M/{print $NF}' \ \| sort \ \| xargs -n1 -iX \ bash -c 'echo === X ===; \ cif_validate \ --dic ~/struct/CIF-dictionaries/cif_core.dic \ X \ --check-all \ --do-not-check-tag-exists-local' \ ) >& validate-pressure-temperature.log	9012135.cif
