Hi, Yesterday, Mark Jensen alerted me to two problems in the current version of artemis. The first is a situation wherein artemis ignores certain guess parameters. The second is a situation in which artemis fails to display the header information from the feffNNNN.dat file as in this screenshot: http://leonardo.phys.washington.edu/~ravel/software/exafs/images/artemis/art... The first problem is due to the fact that artemis gets confused by capital letters in parameter names. That is, "deltar" is ok, but "deltaR" is not. This will be fixed in the next release. The work-around for this problem is to avoid capital letters in parameter names. The second problem was for the somewhat strange situation of running artemis on a unix machine and having made the feffNNNN.dat files on a windows machine. Because of a mistake that I made in the code that fills in the text box in the picture above, artemis got confused by the different end-of-line conventions on windows and unix. How embarassing! This will also be fixed soon. The work-around is to run feff and artemis on the same kind of computer. I want to thank Mark for the excellent bug report and for his help in troubleshooting.
