Hi Hashem, I would suggest you try the following: use the latest version i.e Artemis 0.8.011 if you have not or process your crystallographic data externally with Feff6 before inputing your generated data into ArtemisIf you are using Windows Vista you could also possibly try what you had previously done on Windows XP.

However, it failed to run and an error message indicated that there is something wrong with the crystallographic data. I used the crystallographic data of hydrotalcite from different sources, but encountered the same problem. Can you please help identify the problem and run feff?   Please find attached the crystallographic data for hydrotalcite.   I appreciate your help.   Regards, Hashem Stietiya Louisiana State University   _______________________________________________ Ifeffit mailing list Ifeffit@millenia.cars.aps.anl.gov http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit
