291792 (current)	2024-05-09	Inserting Z values into entries of 9 range, mostly missing.	9010939.cif
282067	2023-03-26	cod/ (saulius@tasmanijos-velnias) Adding AMCSD ID to the '_cod_related_entry_' data loop.	9010939.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.	9010939.cif
202019	2017-10-14	cif/ Marking COD entries in range 9 that are known to be related to ChemSpider entries using the _cod_related_entry data loop.	9010939.cif
176725	2016-02-18	cif/ (antanas@echidna.ibt.lt) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in range 9.	9010939.cif
120115	2014-07-12	Adding DOIs to range 9 structures.	9010939.cif
85285	2013-05-05	cod/ (saulius@koala.ibt.lt) Removing outdated _amcsd_database_code data items from all series 9 CIFs.	9010939.cif
35913	2012-02-28	cif/9/ Reorganising range 9 into a prefix-directory tree. Range 9 is the last range to be reorganised.	9010939.cif
1210	2010-06-10	cif/9/ Updating 13213 AMCSD CIFs, taking new data from the AMCSD database and adding the assigned AMCSD numbers.	9010939.cif
1071	2010-04-10	cif/9/ Updating COD entries from AMCSD, processed in the AMCSD-resynchronisation-2009.06.24/ directory. Entries are updated if they could be unambiguously mapped to a unique COD number by automatic search scripts in AMCSD-resynchronisation-2009.06.24/.	9010939.cif
966	2010-01-30	cif/ Adding _cod_database_code tags to all COD entries. Adding tag description to the cif_cod.dic dictionary so that COD entries can be validated.	9010939.cif
903	2009-11-23	cif/ Setting svn:keywords property on those CIFs that did not have them.	9010939.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	9010939.cif
