| 301851 (current) | 2025-08-21 | Add cross-references to PubChem compounds in COD range 7/05/ Each referenced PubChem compound corresponds to the full crystal structure. |

| 202017 | 2017-10-14 | cif/ Marking COD entries in range 7 that are known to be related to ChemSpider entries using the _cod_related_entry data loop. |

| 180066 | 2016-03-26 | cif/7/05/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 7/05/12. |
7051284.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. |

| 129439 | 2015-01-07 | cod/ (robertas@burundukas) Correcting values of _exptl_crystal_density_meas and _exptl_crystal_density_method data items: codsql "select codid from validation where message like '%\\'_exptl_crystal_density_meas\\' value \"not measured\" is %'" -NB \ | codid2file \ | xargs perl -i -pe "s/_exptl_crystal_density_meas\\s+'not +measured'/_exptl_crystal_density_meas ?/i; \ s/_exptl_crystal_density_method\\s+('not +measured'|\\?|none)/_exptl_crystal_density_method ./i" |

| 106285 | 2014-03-15 | cod/ (saulius@kolibris) Adding the '_diffrn_radiation_probe neutron' data item to those COD CIFs that declared neuron radiation in their _diffrn_radiation_type data field, and did not have a _diffrn_radiation_probe item yet: codsql 'select file from data where radiation is null and radType like "%neutron%"' -NB \ | codid2file \ | xargs -i sh -c 'test -f {} && ( set -x; echo _diffrn_radiation_probe neutron >> {} )' Two files that had no newlines at the end were fixed manually. |
