Many thanks Robert.
I was able to import everything after your suggestion.
About : "I don't like the steps in the original mu(E) either - rounding off too soon"
It's because I have brutally rounded the data in excel. The initial data had 6 digits and I was wondering if it could be an issue for Athena.
Thanks again.

According to
http://millenia.cars.aps.anl.gov/pipermail/ifeffit/2013-August/006762.html
limit is 8192
It is possible to rebin the data in Athena...in multiple steps...what it first imports, then export, then
attach the missing higher E data, re-import, rebin...using a near edge step size of 0.2 eV, 0.05 invAng
in the EXAFS and 2 eV in the pre-edge, these two steps were sufficient to reduce the data size to 555 points.
The match between original and rebin does show some small differences but I didn't deglitch first.

I don't like the steps in the original mu(E) either - rounding off too soon,
or is it there at this level in the raw data?
...discrete noise/quantization error at the 1:800 level versus 'traditional exafs' 10^6 counts (1:1000)

Just a quick idea on why I cannot import the .txt file attached with previous email.
I realized that the files contain 11948 points ! (it's QEXAFS data).
Athena might have an hard limit of 8200 points that may be imported in a single file.
