249437 (current)	2020-03-17	cif/2/ Switching from COD_ERROR to COD_ENTRY_ISSUE CIF data items to describe the retraction in COD entries retracted via the the Acta Cryst. E editorial: William T. A. Harrison, Jim Simpson and Matthias Weil, Acta Cryst. E 66 (2010) e1--e2 http://journals.iucr.org/e/issues/2010/01/00/me0406/index.html http://journals.iucr.org/e/issues/2010/01/00/me0406/me0406.pdf doi:10.1107/S1600536809051757 (http://dx.doi.org/10.1107/S1600536809051757)	2206829.cif 2206829.hkl
192456	2017-02-22	cif/ Updating a link to the collection of the original retracted structures in the boilerplates of retracted entires: changing from HTTP protocol to SVN.	2206829.cif 2206829.hkl
180988	2016-04-03	hkl/2/20/ (antanas@echidna) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/20/68.	2206829.cif 2206829.hkl
176774	2016-02-20	cif/2/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/20.	2206829.cif 2206829.hkl
88064	2013-08-29	Adding _cod_database_fobs_code data item to all COD CIFs that have Fobs deposited and did not have this data item yet.	2206829.cif 2206829.hkl
77446	2013-03-27	cod/ (saulius@koala.ibt.lt) Removing atomic coordinates from the rest of the retracted entries: mysql --column-names=0 -u cod_reader cod -h cod.ibt.lt -e 'select file from data where status = "retracted" and flags like "%has coord%"' \ \| xargs -i find cif/2/ -name .svn -prune -o -name {}.cif -print \ \| xargs -t -i sh -c 'perl -i -ne "if( /^_atom_site_occupancy$/) { print \$_, \".\" . (\" .\" x 9) . \"\n\"; exit 0 }; print" {}' (the old coordinates before the retraction can be found in the COD retracted/ directory).	2206829.cif 2206829.hkl
77439	2013-03-27	cif/2/20/68/ (saulius@koala.ibt.lt) Adding DOI to the '2206829.cif', mainly to check if the 'retraction' flagg will be recorded in the COD MySQL databases after the commit.	2206829.cif 2206829.hkl
32112	2012-02-03	cif/: committing an update of 45+ thous files, with information appended from the originals.	2206829.cif 2206829.hkl
26848	2011-09-28	cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree.	2206829.cif 2206829.hkl
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).	2206829.cif 2206829.hkl
26025	2011-09-16	hkl/2/ Adding assigned Fobs files for the 1980-2010 IUCr data.	2206829.cif 2206829.hkl
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.	2206829.cif
18076	2011-04-19	cif/, retracted/ Processing retraction of the 11 more structures, as mentioned in http://journals.iucr.org/e/issues/2011/03/00/me0442/index.html.	2206829.cif
5310	2011-01-02	cif/ Running cif_fix_enum with the core CIF dictionary on COD ranges 2, 8 and 9. Range 9 remained unchanged, and in ranges 2 and 8 there were 17309 modified files, most changes were fixes enumerator case.	2206829.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.	2206829.cif
853	2009-11-16	cif/ Reconstructing spacegroup designators from the symmetry operators were possible. The comands used can be found in the log file reformat-spacegroups-2009.11.14.log committed with the current revision. Only lines that contained spacegroup designators were changed, and all files pass vcif test after the conversion.	2206829.cif
326	2008-04-03	Adding all Acta Cryst. B, C, and E missing retrospective CIF files up to 2008 February, generated from the files that were automatically downloaded from the IUCr site.	2206829.cif
