180509 (current)	2016-03-26	cif/7/21/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 7/21/78.	7217897.cif
134573	2015-04-01	cod/ (robertas@burundukas) The 'cif_fix_values' script was applied on the CIF files, which had notes in the COD database's table 'validations' generated by the 'cif_validate' validator about misspelling of the enumerable values of the data item '_symmetry_cell_setting'. There was used the option '--fix-only-misspelled'. And there were used 'cif_filter' later in the pipe. Read the log for more details. There were 595 distinct CIF files which had messages from validator. The 'cif_fix_values' script generated 417 messages about corrected misspelled values of enumerators to the log file. Some messages were generated by 'cif_filter' and some changes by the 'cif_filter' were done without messaging to the log file. The 'cif_fix_value' script corrected the enumerators of all data items presented in the file for the replacement of the misspelled values.	7217897.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 {}'	7217897.cif
