[Ifeffit] sorting files in Athena

[Barton, David (DG)]

Dariusz,

One other reasonable solution to this problem is to request that your
beamline owner change their file naming scheme to truly name the file
something like "scan_0001rXXX, where the XXX is the scan number and it
is padded with zeros... Such as: scan_0001r001.dat, then all problems
with lexigraphical ordering in Windows and other platforms is solved
because scan_0001r001.dat will then be listed before scan_0001r010.dat
in the file list.  As a result, programs that import lists of files (not
just Athena) will then be able to handle multiple files in the manner
that you expect.

Dave

this is a typical problem with the Windows file selection dialog. 
Windows always puts the file, which is currently selected, at the first 
position of the files list. Now, when you're shift-clicking on your last

file, you automatically select this one. That's why file 31 is in first 
position.

The easiest workaround for this issue is to select your files backwards,

i.e. first click on file 31, then shift-click on file 1.

Now, with HASYLAB files, it gets a little more complicated, due to 
filenames like scan_00001rxx, where xx is the scan number during a 
QEXAFS scan. I usually just open them in two chunks, one with xx=1-9 and

then xx=10-99. This way, you can use the lexical sorting of Windows.

Cheers,
dominik
