I am analyzing Neodymium Oxide with G.I.Feffit. I have two paths and I'm having trouble showing the contributions (chi data, Forward and back Fouirer Transform) to the fit from each path. I ran into a problem with the Sigma2 for the second path, sigma2_2. When I guess sigma2_2 I can print out the individual path contributions to the fit with the fitted parameters factored in. If I define, def ( ), sigma2_2 = sigma2_1 then the path contributions that I try to print out do not have the debye-waller parameters factored in. I have tried the analysis with feffit245 and the path contributions it shows seem be consistent with the fit. So, I figure I must be writing something wrong in my command file. I have attached the fit command files, log files, and contribution graphs for when I guess sigma2_2 and define sigma2_2 = sigma2_1. In the graphs black = data, red = fit, green= contribution from path 2, blue= contribution from path 1.

Thanks,
