Hi Matt,
Thanks for your reply !

  a.. Sorry, and I don't mean to pick on you in particular, but just to
  b.. emphasize Bruce's response.  Did you really think your question could
  c.. be answered with the data files?  
Well, I suppose the data file were necessary to understood what kind of problem I am seeing and if its really reproducible on some other PC, to be called is as a problem.
That’s what I understood from Bruce´s message.

  a.. DAthena tries to read any data file, but beamlines seem to be able to write very odd data files, and 
  b.. it is inevitable that some raw data files will cause problems.
I fully understand that different beamlines will produce different type of files depending on their preference. My message was to check if I can get some help if I have this kind of data set !  

  a.. Well, what would be your guess at could be going on?  What have you 
  b.. tried so far? 
  c.. I look at those files and  two thing come to my mind:  a) Column 1 
  d.. appears to be  the highly useless point number.   It seems perfectly 
  e.. believable that DAthena might think this column is the energy column, 
  f.. and   it appears to be in keV, not eV.    b)  Columns 3 to 10 have 3 
  g.. significant digits each.  Thus, without even trying to read the file, 
  h.. it's clear that 9 of the 14 columns are of no use.    The file also 
  i.. has an extra line at the end without data.
What I understood so far is dathena doesn’t have an problem to read a single data file. It works like charm when I open files one by one and select the energy units in eV.
The problem occurs during import of multiple files where I can choose Energy unit to eV but its gets applied to only first file in import. 
Having an Energy unit option in preprocessing tab could be useful ( its just some wild thought ) so that same setting will be applied to all the files imported. 

Well in the end I can import files one by one but then I have hundreds of data files, and that’s what made me to subscribe and mail to Ifeffit mailing list to see if I can get any help.
