Hello Matt,
Did you try using /Applications/Ifeffit/bin/feff6 as the preferred feff executable in Artemis? That's what the error message was suggesting you try.
I did try, no success
Can you verify that you have /Applications/Ifeffit/bin/feff6?
verified, I do have it. In the meantime I made an interesting discovery that some of you will certainly be able to explain: If I launch Artemis using the double click on the application icon I DO get the error message and feff does not run, regardless of which application I choose for the graphics However: If I launch the program from the terminal window, I do not get the question on whether to choose Xwindow or Aquaterm, the default being apparently Xwindow PGPLOT, and everything runs smoothly. So, what is the origin of the error message that I get when I launch the program from the icon?
