Sorry, and I don't mean to pick on you in particular, but just to
emphasize Bruce's response.  Did you really think your question could
be answered with the data files?   DAthena tries to read any data
file, but beamlines seem to be able to write very odd data files, and
it is inevitable that some raw data files will cause problems.

Well, what would be your guess at could be going on?  What have you
tried so far?

I look at those files and  two thing come to my mind:  a) Column 1
appears to be  the highly useless point number.   It seems perfectly
believable that DAthena might think this column is the energy column,
and   it appears to be in keV, not eV.    b)  Columns 3 to 10 have 3
significant digits each.  Thus, without even trying to read the file,
it's clear that 9 of the 14 columns are of no use.    The file also
has an extra line at the end without data.

It might be worthwhile to convert the files to simpler format that DAthena.
