[Ifeffit] running diffkk and deltaf

[marie-helene.tuilier at uha.fr]

Hello everyone,

First, I would like to pay homage to the authors of that fairly 
user-friendly software, which is very useful for a  diffusion of XAFS 
technique. Thanks to the detailed explanation found in the various 
tutorials, I became able to use it almost without any help.
Despite every thing, I encounter now some difficulties running DIFFKK and 
DELTAF in IFEFFIT.  I am trying  to reduce DAFS data of a metallic nitride 
film at the Ti K-edge and  I need anomalous scattering factors. First I 
built diffkk.inp and deltaf.inp files following the instructions given by 
Matt Newville and Julie O. Cross in the Diffkk tutorial. Then, I begin to 
run diffkk in ifeffit 1.2.11c as follows:

ifeffit> run diffkk 
ifeffit> read diffkk.inp

or
 ifeffit> run deltaf 
ifeffit> read deltaf.inp

I become only a file named userenv.log  with such comments: " cannot 
process autoexec.bat". Perhaps I loaded a wrong version of IFEFFIT.
Thank you in advance.

Marie-Hélène
