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.

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
