Hi Dr. Bruce Ravel

I have Cl K-edge XAS data (as attached for example) that I took from beamline 9.3.1 ALS four years ago. I can’t import the data into the Athena, what’s a problem. I want to study XANES of the data. Thank you,

Amphol, I am forwarding your question (and my answer) to the Ifeffit mailing list, which is the appropriate venue for asking questions about the software. Please subscribe to and use the mailing list in the future. The problem with the data file you attached is that there are lines with just numbers before the line with the column lables. This confuses Ifeffit and therefore confuses Athena. The simplest solution is to comment out (or, I suppose, delete) the first few lines in the file, like so: # 7 # 008 # # # Mono ev Isignal Izero Ph E 2800.000 -0.05113220 0.30488586 2799.981 2800.500 -0.05165100 0.30612183 2800.482 2801.000 -0.05169678 0.30537415 2800.976 Regards, B -- Bruce Ravel ------------------------------------ bravel@bnl.gov National Institute of Standards and Technology Synchrotron Methods Group at NSLS --- Beamlines U7A, X24A, X23A2 Building 535A Upton NY, 11973 My homepage: http://xafs.org/BruceRavel EXAFS software: http://cars9.uchicago.edu/ifeffit/Demeter
