Hi Tamas,

I'm trying to run feff to do the feff paths calculation the same way I've done before (feff file from TkAtoms and the executable feff6l are in the same folder), and now it just doesn't want to work. Hitting feff6l causes the opening of the DOS window, but it closes immediately and doesn't do the calculation. Does anyone know what's the cause of this? (I have the updates version of Ifeffit and the updater, too.)

With 1.2.4(+ the updates), it should be that clicking on the feff6l batch file brings up a dialog to browse for feff.inp, and then runs feff6l on that file, in that directory. I think this batch file could be copied from C:\Program Files\Ifeffit (or whereever Ifeffit is installed) and still run OK. But I believe a shortcut to the executable (feff6l.exe) in another directory will not work, as this executable needs to find DLLs to run properly. That's why there are the batch files. If the proper environmental variables are set and the Ifeffit directory is in your path, the executable should run from a DOS command window. You could add this to autoexec.bat (or look at feff6l.bat): SET IFEFFIT_DIR=C:\Program Files\Ifeffit SET PATH=%PATH%;%IFEFFIT_DIR% SET PGPLOT_DIR=%IFEFFIT_DIR% SET PGPLOT_DEV=/GW or set these environmental variables from the Control Panel (Generally Control Panel -> Settings -> Advanced -> Environmental Variables, though it does vary with versions of Windows). Actually, for Feff6, only the path needs to be set to include the Ifeffit directory. Please let me know if these suggestions don't help enough to get fef6l working for you... --Matt
