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.

Hello,
 
I have some issue to import a file in Athena: just a simple x-y column (.txt attached with this email).
 
Ti K-edge.
Data range in the file  : 4916.30 up to 5436.88 eV.
Issue: only data up to 5260 eV are imported (see screenshot: bug-importation).
 
Version: Demeter 0.9.24
System: Windows 7 Professional SP1
 
Well, I hope it's just not me not being able to find a proper way to import the file...
