178611 (current)	2016-03-21	cif/4/07/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 4/07/22.	4072270.cif
132589	2015-03-02	cif/ (antanas@koala.ibt.lt) Multiple CIFs contained incorrect '_refined_diff_density_rms' tag values, consisting of the actual numerical values and a trailing substrings that were accidentaly concatinated to the end of the values. The values were malformed upon deposition due to incorrect comment markup (comments were not prefixed with a '#' symbol). The folllowing command was carried to remove the trailing substrings: find . -name .cif \| xargs perl -0777 -i -pe "s/_refine_diff_density_rms\s\'(\d\.\d)\s.*/_refine_diff_density_rms \1/" After the modifications 'cif_filter' script was used on all affected CIFs and changed values were inspected manually to avoid introduction of new errors (the trailling string might not be an artifact, but a misplaced e.s.d. value or a measurement unit symbol that implies the need of numerical value conversion).	4072270.cif
130086	2015-01-23	cod/ (robertas@burundukas) The 'cif_fix_values' program was applied to CIFs that have generated the validation messages containing tag '_exptl_crystal_density_meas'. 16946 CIFs had a values that were perceived as 'not measured' and they were changed to '?'. The total of 17089 CIFs was changed. Those that were not corrected by 'cif_fix_values' were reformatted by the parser (e.g. a doi tag was moved to another place). The processing command was: mysql -u cod_reader -h www.crystallography.net cod -e \ 'select distinct codid from validation \ where message like \ "%tag%_exptl_crystal_density_meas'\''%"' -NB \ \| xargs -i sh -c 'cif_fix_values {} \ \| cif_filter --add-cif-header {} \ \| sponge {}'	4072270.cif
