Dear Rietvelders, the INDEX program as distributed on www.bgmn.de for free is now multithreading enabled. It does a full exhaustive search and takes care for the different statistical peak position errors/weightings as delivered by EFLECH, which was multithreading enabled too. See Z. Kristallogr. Suppl. 26 (2007) 197-202
The program triplet TEIL/EFLECH/INDEX is available for Windows and Linux, command line only. Indexing triclinic K<sub>2</sub>Cr<sub>2</sub>O<sub>7</sub> takes 2 hours on a 2.4GHz Phenom using all 4 cores, scanning from cubic to triclinic. Regards Joerg Bergmann
