Crystallography Open Database

DIFFRAC.EVA now supports a reference pattern database derived from the free-of-charge Crystallography Open Database (COD) for phase identification.

This reference pattern database contains d/I-patterns calculated from crystal structure data taken from the Crystallography Open Database, which integrates crystal structure data published by the IUCr journals, the American Mineralogist Crystal Structure Database (AMCSD), and other sources.

DIFFRAC.EVA generally supports phase identification using several databases simultaneously. However, the current license policy of ICDD does not permit its databases (PDF) and results generated from its databases to be combined with other non-ICDD databases. Accordingly DIFFRAC.EVA allows to perform simultaneous searches on

  • the COD reference databases and any user reference databases
  • all PDF2 and PDF 4 databases and any user reference databases

Simultaneous search on any PDF reference databases and the COD reference database is NOT supported, attempts to do so will result in an error message.

As usual in scientific practice, COD users are kindly asked to cite the following publication:

S. Grazulis, D. Chateigner, R. T. Downs, A. T. Yokochi, M. Quirós, L. Lutterotti, E. Manakova, J. Butkus, P. Moeck and A. Le Bail: "Crystallography Open Database - an open-access collection of crystal structures", J. Appl. Cryst. (2009). 42, 726-729.

Please note, that bibliography data is provided in most COD entries; this enables citations of individual COD entries where applicable, too.
