Hi, I can propose you few things: read the manual available on the webpage of feff, find in the internet some presentations (pdf or powerpoint) of Bruce Ravel, Ania Wolska or Moniek Tromp - there are some nice examples how to define/use multipaths. about the multipaths - I do not understand completely what you mean. Do you import the experimental data from the file and calculate in Artemis paths from the structure file? Does single paths fit to experimental data? What about the phase correction? What sample you investigate (the symmetry of sample I mean - is some inorganic or organic, semiorganic)? What is the value of NLEG parameter in feff.inp file? Maybe some multipaths are missing. And finally which plots - in R or in k scale? what are windows for R and k space for fitting? The best would be if you send a project file to see it. kicaj W dniu 12-03-11 11:02, Krishnananda ShAsTri pisze:

Hi,

I am a Physics student. I am new to IFEFFIT. I have installed IFEFFIT to windows and Athena was not so difficult to learn. But I am not getting how to add multiple paths in Artemis. I tried by taking one example but experimental and theoretical plots were not well matching. What may be the reason for that and also suggest me if any videos are there to learn.
