Hi Marie, Sorry about this, and for the delay in responding. Currently, diffkk and deltaf are not currently included in the Windows Ifeffit distribution, and are not available simply as ifeffit commands. The "almost-good" news is that diffkk has been ported to Python, which can, in principle, be downloaded and run on Windows machines. This code was ported by Adam Webb from Fortran (written mostly by me) to Python. For now, this code is available from http://cars.uchicago.edu/ifeffit/diffkk The "less-good" news is that, when I try to use this myself, I am getting important differences between the Windows and Unix version -- and the Windows version is definitely wrong.... In addition, it's more work to get the python code to work on Windows (like, how to get Python to communicate to Ifeffit and what other extensions you might need), which is not currently well-managed. It is possible (though no one has done it yet!) to make a standalone executable. Probably, we need to figure out why it's not working on Windows.... I will try to do work on this, but life is complicated this summer, so I can't promise when this can be completed. --Matt On Tue, Jul 7, 2009 at 9:20 AM, wrote:

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.
