[Ifeffit] How can I fit the results obtained from FEFF9 to the experimental data using the ARTEMIS.

Hi, I have started using FEFF9 recently. I am using it to generate theoretical model for some copper compounds and complexes. As you have mentioned in one of research article' Nuclear Instruments and Methods in Physics Research A 619(2010)28-32' How can I fit the results obtained from FEFF9 to the experimental data using the ARTEMIS. I have tried to search the answer on the ifeffit mailing list but unable to find a satisfactory one. With thanks in advance -- Dr. Abhijeet Gaur
