[Ifeffit] Can Artemis Simulate a FT spectrum?

Hi, I was wondering if it was possible for Artemis to simulate a FT spectrum, I have a model and would like to visually see what the simple R-space spectrum would like so see if there are any similarites at all to my sample. I'm not sure if the reason it doesn't converge is because the signal level is too low or if it is the wrong model all together. Robert
