| 282053 | 2023-03-24 | cod/ (saulius@tasmanijos-velnias) Updating the existing COD records from the recent AMCSD downloads: - Adding AMCSD IDs to those COD records that exacly matched the AMCSD structures (comparing unit cells, space groups, coordinates and measurement conditions) but did not yet have the AMCSD ID; - Adding new mineral names, compound sources, measurement conditions (when those were missing) and other informations from the AMCSD CIFs. |

9008987.cif |
| 255 | 2008-03-10 | Redepositing all AMCSD (9*series) COD CIF files. This redeposition regenerates AMCSD (9* series) files, 10011 entries total, from the original source CIF file cifdata.cif found on the CD received from Armel. Most importantly, the truncated formulas seem to be corrected. The files are not folded, i.e. they have lines longer than 80 characters (conforming CIF 1.1 specification, but not CIF 1.0 specification), and are otherwise syntactically correct. Some missing coordinates were fixed manually, restoring them from the AMCSD site, and non-ASCII symbols were fixed automatically during filtering. After the redeposition, the cifs-with-errors.lst was regenerated using the following command: find -name \*.cif \ | xargs -n1 -iI sh -c 'vcif -l 2048 I || echo I' \ | grep -vE 'CIF|ERR' \ | sort > cifs-with-errors.lst & |
9008987.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/' |
