Hey Ian, Basically, ditto on what Matt said. 300 columns is not something that Athena is designed to do. My opinion is that you (or the beamline you visit) should have some kind of tool to turn a file that into XAS. As for the energy dispersive thing -- it's long been on the to do list. From time to time, I have poked at it, but I have never developed an algorithm that I actually like. Even the algorithm in the old Athena was unstable and required very good initial guesses. The best parts of A&A are the parts that I have needed in my career. I've never actually done my own experiment at an ED beamline, so my software doesn't really support it.

Dear All,
Here’s an issue I recently encountered while trying to handle some very large /in situ/ datasets in Athena; it may be by design/an inherent limitation, rather than a bug, though:
(I am running Demeter 0.9.21 pre and Demeter 0.9.20 , both x64 on Windows 8.1 x64 on separate machines).
Each of my datafiles contains over 300 columns of u(E) data as space delimited plain text, however when I try and import them to Athena the import window will only display checkboxes up to column 87.
I’ve attached an example datafile and a logfile to this email. (The data is very poor, but that shouldn’t be an issue for debugging…) I’ve also attached a copy of the datafile as it came from the beamline – this also displays the issue, so it’s nothing I’ve done to the file.
On a related note, is it possible for the energy dispersive data calibration to be added back to Athena? To get the calibration parameters for this data I had to use the (very) old version!
Thanks,
Ian
