"Web7. Running a fit¶. ARTEMIS is, admittedly, a complex and non-intuitive program. There are good reasons for ARTEMIS being the way it is, although those reasons may not be clear if you are coming to the program for the first time. While it is important that easy things be easy in ARTEMIS, letting hard things be possible is central to the intent of the program. " - Exafs software
