Re: [Ifeffit] Athena problem

Hi Elien, I might not be correct but are the results you are showing in the 2nd screen shot coming from the combinatorics? That might be different than “fitting the data” since the combinatorics get those results by using each combination of standard and finding the best fits using those are particular standards. So across all the combinations, the D standard fits best by using a negative value which I think might be different. I am not sure but the tick box might not apply to the combinatorics. Maybe someone else can clarify or correct my interpretation, Chris ********************************************** Dr Christopher Patridge Assistant Professor Department of Chemistry SASE 315 D’Youville College 320 Porter Ave. Buffalo, NY 14201 716-829-8096 / 315-529-0501 patridgc@dyc.edu

Dear,

I was trying to do some linear combination fitting using Athena software. Although the box “All weight between 0 and 1” is ticked I get negative weight results. I have read the online Athena’s User's Guide, but I did not find what the issue can be. Do you have any ideas? Below you can find some print screens of my actions. I also get an “error” (print screen 2), which I don’t understand.

Thanks in advance Elien
