There are a number of known problems with the current version of Artemis. It's pretty much impossible for me to troubleshoot without examples being posted to the mailing list. B On 04/07/2014 11:17 AM, Matt Newville wrote:

Hi Alexander,

I think you may not alone in having this issue. You should be using normalized chi(k) in Artemis, but I don't think Artemis would be reading chi(k) from the project file incorrectly.... Perhaps there is something strange about how you're doing the normalization? Or perhaps it is just a question of what k-weighting is being used for the plot. Unfortunately, the PNGs I see have been cropped and don't show the labels of the axes.

I'm sending this to the Ifeffit mailing list, where you'll probably get a more complete answer.

Dear Mr. Newville,

I came across a problem when I import an ATHENA project after normalization into ARTEMIS. Maybe you could tell me who to contact about this problem. Let me try to explain it in few words:

I normalize my EXAFS data in ATHENA and safe it a s a .prj file. When I open the .prj file in ARTEMIS I noticed, that the amplitude of some oscillations have changed. When I save the chi(k) as .txt, this problem does not occur. When I open the chi(k) text file in ARTEMIS, the normalization and the amplitude of the oscillations are exactly the same as in ATHEN.

I have attached a .png file for the EXAFS in k-space. It is the same .prj file, one time opened in ARTEMIS, one time in ATHENA. To be more specific, the amplitude of the oscillation at k=3 is -1.4 and -1.6, respectively.

Thank you very much for your help in advance!

Best regards from Hamburg, Alexander
