Hi folks, Carlo asked about a simpler way of doing simple, first-shell analysis that what Artemis provides. Let's talk about that. Artemis is complicated program. It may be powerful and effective. Some of you may like it for what it allows you to do. Some of you may consider that it competes favorably against other programs in terms of ease-of-use. Or not. Be that as it may, Artemis is a complicated program and I will be the first to say so. I originally designed and started to write Artemis in a way that would address my analysis needs. I work on some comlicated fitting problems and delve pretty deeply into the guts of Feff and Ifeffit. Artemis' first responsibility is to handle *my* needs. That said, Artemis should not be overtly hostile to novice users. Indeed, there are a number of features in Artemis that were included with the novice in mind: automatic generation of guess parameters when a feff calculation is imported, feedback about unusual values for fitting variables, and so on. I am disinclined to make huge changes to how Artemis works. I like Artemis and it serves my own research needs quite well. The system of various pages -- atoms, feff.inp, feff interpretation, data, path, GDS -- works well for me and gives the Artemis user a high degree of control over the fine details of the fit. That is unlikely to change. We are left with two topics of conversation: (1) What can be done within the framework of Artemis to expedite a simple fit? (2) Should we consider a new application which works differently from Artemis and which is designed principally to handle the simplest problems? #2 is a fine topic of conversation and might be an excellent chore for someone looking to get involved in Ifeffit development. I have some ideas about #1. So it seems do several people on the list. My next message will be about that.
