Hi all, One of the bugs reported last week involved a project file which made extensive use of the "quick first shell" -- or QFS -- feature of Artemis. The bug involved a problem importing such paths from a saved project file. That bug has been fixed in the 0.9.13 release that I announce a short while ago. This project file that triggered the bug reminded me of an issue that has come up at several recent XAS training courses that I have participated in. In situations where rather little is known about the structure of a material, there is a thought that the QFS tool could provide a model-independent way of generating scattering amplitudes and phase shifts for atoms suspected of being in the material. While the QFS tool is a reasonable thing for atoms in the first coordination shell (hence the name!), this is a dangerous practice for atoms at longer distances. Artemis does not police its misuse in this way beyond simply issuing a warning sugesting that you may be doing something inappropriate. A full discussion of this topic is rather lengthy, so I will refer you to a wiki page that I wrote: http://cars9.uchicago.edu/ifeffit/Demeter/QFS If you have considered using the QFS tool for atoms beyond the first coordination shell, please read that wiki page all the way to the end.
