179575	2016-03-24	cif/4/50/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 4/50/40.	4504080.cif
134621	2015-04-02	The 'cif_fix_values' script with an option '--fix-only-weighting-scheme' and 'cif_filter' script were run over CIF files which included an incorrect value of the data item '_refine_ls_weighting_scheme'. Read the log for more details. There were more than 18k CIF files with values to modify. Usually these incorrect values include comment with formulas, but values of this data item must be an enumerator. The script creates new data item '_refine_ls_weighting_details' to store these comments with formulas, and writes the enumerator 'calc' as a value of data item '_refine_ls_weighting_scheme'. There exists some exceptions in the script.	4504080.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).	4504080.cif
