1516637.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). |
