Hi folks, Today I posted new source tarballs of Athena and Artemis on my web site. A new Windows installer will be available later today from Matt's web site. This time there are some big changes. 1. I am now distributing Athena and Artemis in a single source tarball called `horae-001.tar.gz'. http://homepage.mac.com/cparada/GML/HORAE.html 2. Windows users should download and install the new installer package because there are several new library and example files. I will continue the practice of posting replacement executables when I _next_ update Athena and Artemis. 3. I have started numbering Athena and Artemis differently. Both programs are getting within striking distance of becoming the magical 1.0. Because of that and other reasons, I want to start using actual version numbers rather than dates to identify the versions. Athena is starting at 0.8 and Artemis at 0.5. The version number on the source tarball will simply be an incremented counter unrelated to the version numbers of the programs. 4. I have made a very large number of changes to Artemis. I'll refer you to the change logs for all the details. In addition to many, many squished bugs, the most important change is that reading in feffNNNN.dat files now works in a much more sensible manner. You can read in individual feffNNNN.dat files or read in all at once by selecting the feff.inp file. In either case, the feffNNNN.dat files should be grouped in a sensible manner in the list in the skinny part of the window. 5. The other big new feature in Artemis is templates. This is a scheme I am working on to help automate the creation of fitting models. The idea is that after reading in data and a feff calculation, you can select, for example, "FirstShell" from the Templates menu. Artemis reads an external file which described a prototypical first shell fit and generates guess, set, and path parameters that hopefully are close to an appropriate fitting model. For copper data, you can hit the big green fit button right after reading in the template file and get a reasonable fit. Some tweaking is usually necessary, but the templates are a decent start. 6. The most interesting change to Athena is that you can now save your data as a "chi(k) record". This is a special file that has the same structure as a normal Athena project file, but which contains only a single entry. That entry is saved as chi(k) rather than as mu(E). The purpose of this kind of file is for reading into Artemis. The advantage of a chi(k) record over chi(k) column data is that the values for things like the Fourier transform parameters that you chose in Athena will be set in Artemis. As always, let me know about problems and feature requests, Enjoy, Bruce -- Bruce Ravel ----------------------------------- ravel@phys.washington.edu Code 6134, Building 3, Room 222 Naval Research Laboratory phone: (1) 202 767 5947 Washington DC 20375, USA fax: (1) 202 767 1697 NRL Synchrotron Radiation Consortium (NRL-SRC) Beamlines X11a, X11b, X23b, X24c, U4b National Synchrotron Light Source Brookhaven National Laboratory, Upton, NY 11973 My homepage: http://feff.phys.washington.edu/~ravel EXAFS software: http://feff.phys.washington.edu/~ravel/software/exafs/
