Hello Bruce, After a break I just started to use Artemis again and I am delighted about the new features, especially the ability to store and compare subsequent fits in one file. Below I want to submit the bugs that I came accross so far (on Win2000): - If one opens by mistake an input file that is unknown to Artemis (or Athena) this file will be destroyed and cut to about 4kB. Workaround: Just DON'T do this (or keep regular backups). - Funny things happen when one studies an atoms/feff calculation without having loaded an experiment file: I imported an atoms.inp, ran atoms and feff and did two summations (Sum | All included paths ..). For the first summation I included only the first path, for the second summation only the second path. The first summation seems fine, for the second summation Artemis obviously includes both paths. In subsequent summations this effect will continue: all paths used in the past are considered plus the paths currently included. Workaround: Load a 'dummy'-chi file even for just making summations. I was teaching the use of Artemis to a few colleagues. I recommend them to keep a copy of their atoms.inp-files at a separate place for re-use in later projects. If time permits maybe you could account for these issues: - If saving an atoms.inp file via Theory | Write special output | atoms the name 'artemis.stuff' will be provided. Is it possible to change that to 'atoms.inp'? - The link to TKAtoms is missing for newly installed systems. Cheers, Gerrit Schmithals
