Hey Carlo, While I believe that you are indeed running up against one of Athena's weak spots, a mere description is insufficient for me to troubleshoot the problem. I really need a project file or a raw data file that will reliably trigger this problem. I routinely use Athena on data that extends beyond 1200eV, so this is not a generic problem. I recently wrote up some guidelines for how you, the problem reporter, can help me, the problem solver, solve problems quickly and efficiently. Please take a look at http://leonardo.phys.washington.edu/~ravel/software/exafs/bugs.html To everyone reading this mailing list: Please use the suggestions on that web page as appropriate to your problem when communicating with me. I get software-related mail *every day* and am often swamped. Communicating well with me will really facilitate my ability to address your problem.
