| 190396 (current) | 2017-01-11 | cif/2/ (antanas@echidna.ibt.lt) Moving the _atom_type_scat_source data item into the _atom_type loop in entries 2003422, 2003475, 2003531, 2003784, 2004060, 2212009, 2228532. All entries of the loop were assumed to have the same _atom_type_scat_source data item value. |

| 190394 | 2017-01-11 | cif/2/00/ (antanas@echidna.ibt.lt) Moving the _atom_type_scat_dispersion_real and _atom_type_scat_dispersion_imag data items into the _atom_type loop in entries 2003264, 2003293, 2003422, 2003475, 2003516, 2003531, 2003784, 2004060. |

| 176759 | 2016-02-19 | cif/2/ (antanas@echidna.ibt.lt) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/00. |
2003531.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. |
2003531.cif |
| 91933 | 2013-12-28 | cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs. |
2003531.cif |
| 89281 | 2013-10-15 | 2/00/35/ Adding the _atom_site_type_symbol data item to prevent confusion between oxygen and not existant 'Ow' type atoms. |
2003531.cif |
| 32112 | 2012-02-03 | cif/: committing an update of 45+ thous files, with information appended from the originals. | 2003531.cif |
| 26848 | 2011-09-28 | cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree. |
2003531.cif |
| 26029 | 2011-09-17 | cif/2/ Reverting changes of revision 25271: ( cd cif/2/; svn merge -r25271:25270 . ) The problem was that the reprocessed files from IUCr, although were more complete, "resurrected" data errors that were corrected in the previous recisions. The additional data that have been extracted during the reprocessing will have to be merged without overwriting the existing values in COD files, except some explicit and controlled cases (such as publication titles and chemical names). |
2003531.cif |
| 25271 | 2011-09-10 | cif/2/ Adding reporocessed IUCr CIFs for the years 1980-2010. The CIFs now contain more complete bibliography, substance names, correctly unfolded text fields (using the CIF line unfolding protocol), explicitely set cell angles, and _cod_data_source_block fields. |
2003531.cif |
| 966 | 2010-01-30 | cif/ Adding _cod_database_code tags to all COD entries. Adding tag description to the cif_cod.dic dictionary so that COD entries can be validated. |
2003531.cif |
| 846 | 2009-11-14 | cif/ Fixing _journal_volume values that had series letters prepended to them. Now the series letters are appended to the _journal_name_full, if needed, and the _journal_volume is purely numeric. To mimimise textual changes to CIFs this was done in several stages. First of all, a list of _journal_volume was compiled from the COD CIF collection: bash -xc 'find ? -name \*.cif \ | xargs cif_values \ --file \ --tag _journal_volume' \ >& cod-journal-volumes-`-date`.log & giving us a cod-journal-volumes-2009.11.13.log file (committed for reference as well). Then a list of volume names with letters was extracted and most of them transformed automatically into a correct form: awk '$3~/^[A-Z][0-9]/' cod-journal-volumes-2009.11.13.log \ | awk '{print $1}' \ | xargs -n1 -iI \ bash -c 'echo === I ===;\ awk "/^#/,/^data_/{print}/^data_/{exit}" I > tmp-$$; \ cif_adjust_journal_name_volume I \ | grep -E "_journal_name_full|_journal_volume" >> tmp-$$; \ awk "/^data_/,/\$eof/" I \ | grep -vE "^(data_|_journal_name_full|_journal_volume)" >> tmp-$$;\ mv -v tmp-$$ I' Note that this procedure assumes that all tags are at the beginning of the line, each value follows its tag on the same line, and there is only one tag per line. This procedure is not suitable for general CIFs, but fortunately, only very few CIFs in COD do not conform these rules. After the automatic conversion, a syntax check was run: svn st ? \ | awk '{print $NF}' \ | xargs -n1 -iI sh -c 'echo -n I"\r"; vcif -l 2048 I || echo "!!! I !!!\n"' Entries that were found to have errors (very few, less than 10) were reverted and fixed manually. The entries that had letters embedded into them were grepped separately: awk '$3~/[A-Z][0-9]/' cod-journal-volumes-2009.11.13.log \ | awk '$3~/^[^A-Z]/' and fixed manually. After all fixes, the previous 'vcif' test was rerun, yielding no syntax errors, and in addition a 'cif_filter' roundtrip test was run: svn st ? \ | awk '{print $NF}' \ | xargs -n1 -iI \ bash -c ' \ echo -en I "\r"; \ diff \ <(cif_filter I >& /dev/null) \ <(cif_filter I | cif_filter >& /dev/null) \ || echo "!!! I !!!\n"' This last test discovered one misspelled '_journal_yrae' tag in the 2/2003193.cif entry that was fixed by hand. |

| 20 | 2008-01-26 | Removing white space at the end of all lines from all COD CIF files: in the cod/cif/ directory: ff \*.cif | xargs perl -i -pe 's/\s+\n$/\n/' |
2003531.cif |
| 19 | 2008-01-26 | Changing all end-of-line codes from DOS style to UNIX style in all COD CIF files, for more convenient processing: In the cod/cif/ directory: ff \*.cif | xargs perl -i -pe 's/\r\n/\n/' |
2003531.cif |
| 14 | 2008-01-14 | Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files. |
