Hello, I have been using SIXPACK to process my S K-edge XANES data from SSRL beamline 4-3. I am using SamView to average 5 scans (to improve S/N) for each sample. Then I save the averaged file (.avg) and open in the SIXPACK Background Removal application for normalization. All data sets seem to be working great with this method except one. This one opens fine in SamView, but Background Removal cannot open the averaged file. Here is the error message: *** read_data: error opening file *** C:\sixpack/test.inp pre_edge: no energy array? pre_edge: no energy array? I have saved the averaged file as a .txt file to look at it (.avg and .txt files attached), and I see an energy array. How can I open and use this in SIXPACK Background Removal? Thank you in advance, Julie Muretta
