Hi Carlo and Ying,
Does it means that if the sample is a random solid solution at experimental
temperature, in principle, you would be able to simulate the EXAFS spectra
whichever be the Mo/W ratio in the second shell coordination in the
Feff.inp, am I right?
Thanks, Yordy

This is my fault... and I apologize for the sloppiness and for being late in fixing this. I've been mixing 'development/testing' and 'production' versions, and haven't been very good at keeping them cleanly separated. I think I have this mostly under control now, but I will have to work on a decent "test suite".
I think I found another reason to make a 1.2.11c version too, that the mixing of "devel" and "production" caused an experiment in how fitting was done to be the default, so that the reported chi-square doesn't actually match the documentation (instead of summing real and imaginary parts, it sums real and magnitude components of the misfit, which is part of an experiment to see how Feff8.5 worked for XAFS. Using Magnitude as well Phase for another way to report chi-square and misfits is potentially a useful approach, but it's not what is documented. Anyway, mixing devel and production versions like this (for the past couple years, really) is very sloppy on my part, and I apologize again.
I actually have an ubuntu box now, though I built pgplot from source, and have never made a .deb file. There is a new source kit at http://cars.uchicago.edu/~ifeffit/src/ifeffit-1.2.11c.tar.gz I'll post this to sourceforge this afternoon, and I'll also make a new DLL for Windows and post all of these on the download page. I'll also make a new updater for Windows.

Well, now I have "pgplot5", "ifeffit", "perl-ifeffit" and "python-ifeffit" from binaries and "libperlxray" "horae" and "demeter" built from source (Bruce SVN).
Everything seems fine but I still do not understand why ifeffit 1.2.11 has all these "IFF str = *" output as stated also by Gareth in his "Ifeffit 1.2.11b terminal output" post. Is it normal?

I've uploaded source kits for Ifeffit 1.2.11c to the cars.uchicago.edu and sourceforge.net download sites.
I have a Windows dll made for this bug fix version. If anyone is interested, this is currently at http://cars.uchicago.edu/~ifeffit/updates/011/bin/ifeffit_12.dll
This should be a drop-in replacement for the IFEFFIT_DIR\bin\ifeffit_12.dll on your system. Artemis.exe will not be updated from this dll, as it has this dlls "compiled in". Bruce will have to make a new Artemis.exe, and then we'll make a automatic update.
Sorry for all the trouble,

Subject: [Ifeffit] Hexagonal WO3 To: ifeffit@millenia.cars.aps.anl.gov Message-ID: Content-Type: text/plain;charset=iso-8859-1;format="flowed" Dear All
Recently, I got one compound, W/Mo oxide, which has the similar structure with hexagonal WO3. We tested the EXAFS of W L3 edge and Mo K edge of this compound. So, we use the hexagonal WO3 model to refine the structure of our compounds. My question is that how can I get the FEFF file of this compound. Can I directly change some of W to Mo in FEFF file? or Do I need to add the Mo in the atom file? I do appreciate your help.
Best wishes Ying

There are several ways to do this, depending on what you are trying to find out. If you change W to Mo in the atoms input file than you are really making MoO3. What it seems like you need to do is to generate the FEFF input file from the WO3 structure, then replace the central atom with Mo. This will give you the first path which is likely oxygen. The second longest set of paths are likely to be W/Mo and you can do two things, one is to generate a FEFF calculation with W in this position and then make a second calculation with Mo and use both paths to fit the Mo environment. You will have to be careful about multiplicities though since by starting with the WO3 structure, you are assuming some degeneracies in the paths. The advantage is that you potentially have some multiple scatteing paths available to use.
Another approach is to generate the FEFF input file from WO3, look at the near neighbors and then generate some "quick first shell" paths for the nearest neighbor (oxygen) and then two fro the next near neighbor (one with W and one with Mo). The difference here is that you now have uncorrelated paths with no implied degeneracies. You cannot use this to fit multiple scattering paths.
I guess that my approach would be to start with the latter, more simple approach first to try to understand the problem. If I see that the environment looks like it is possible to fit with multiple scattering, I would move to the first approach, being careful to realize that in a solid sloution compound, the occupancy of the second shell of metal atoms is probably random and not perfectly ordered like a FEFF input file with substitutions would be.
Hope this helps.
