I just installed the new version (0_9_20_(64)_pre9) and have noticed that atoms (integrated or stand alone) cannot generate feff8 input file anymore. You can still set it up in the preference but has no action and feff8 is not anymore in the selectable options. Was it wished?
This was by design. That is, the lines of code that expose the feff8 options in the style menu in Atoms were commented out. I should explain why I did that. 1. I want to support feff8, but I want feff8 support to be as good and as natural in the context of doing EXAFS analysis as is the current feff6 support. Feff8 and feff6 are sufficiently different that I cannot easily support feff8 without writing a significant amount of code. 2. Matt and I have been working on the version of feff 8.5 which John and his group have kindly released under a redistributable license. This work in progress can be found at https://github.com/xraypy/feff85exafs We need to do some work with this code base to make it easier to integrate into and use with Larch, Demeter, and other applications. There is still quite a bit of work to be done. Help would be welcome. 3. Once that version of feff8 is ready for use, I will retire the version of feff6 that comes with the software. 4. The differences between the input files of feff6 and feff8 and pretty slim. While inconvenient, it is not a show stopper to make those modification to your input file before running feff8. I want to emphasize that my main concern with Artemis is to provide a solid user experience for the chore of EXAFS analysis. I acknowledge that people have very good reasons to use Feff and even my Atoms program in other ways. Until the redistributable version of Feff8 is ready for use in Demeter, I see my main priority to be supporting EXAFS analysis. For now that means feff6. All that said, there is a command line version of atoms called "datoms". It gets installed into your execution path when you install Demeter on any of the platforms. It has a command line switch, "-8", which does what you want. http://bruceravel.github.io/demeter/pods/datoms.pl.html B -- Bruce Ravel ------------------------------------ bravel@bnl.gov National Institute of Standards and Technology Synchrotron Science Group at NSLS --- Beamlines U7A, X24A, X23A2 Building 535A Upton NY, 11973 Homepage: http://xafs.org/BruceRavel Software: https://github.com/bruceravel
