| 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. |

| 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. |
