[Ifeffit] Artemis

[Richard Mayes]

Alain,

I had a similar problem trying to run FEFF8.2 in Artemis on my WinXP
machine.  The simple fix is to have a folder outside Artemis where you
"store" the FEFF executable and an input file.  FEFF will write the
feffnnnn.dat files to that folder.  Then, import the input file into
Artemis, as long as the feffnnnn.dat files are in the same folder as the
input file, it will work.

I can't help you with your other question regarding why the plots don't
reflect your fit parameters.  It might help others though if you send the
project file to look at.

For those who don't have access to PowerPoint, a pdf of Alain's ppt is
attached.
