[Ifeffit] Learning IFEFFIT

Hi, I am a Physics student. I am new to IFEFFIT. I have installed IFEFFIT to windows and Athena was not so difficult to learn. But I am not getting how to add multiple paths in Artemis. I tried by taking one example but experimental and theoretical plots were not well matching. What may be the reason for that and also suggest me if any videos are there to learn.
