I am looking for some help with a possible error on my part or bug associated with exporting normalized mu(E) spectra from Athena 0.9.24 64-bit on Windows 10 Pro 64-bit. I have some Si XANES data with a challenging background shape that is well removed through careful normalization in Athena, as long as the "Flatten normalized data" option is checked. When I save the current group as norm(E), what is saved is the non-flattened normalized data. The checkbox for flattening the data has no effect on what is exported despite changing what is plotted. I have verified this by comparing the files exported the the flatten box checked or unchecked. I have tried this with multiple data files loaded in multiple formats (raw beamline data, simple two-column E and mu data, PRJ files) and the effect is always the same. It is also unaffected by the normalization ranges I select. No matter what options I select Athena 0.9.24 will only save non-flattened norm(E) data. This behavior is different from what I remember, and I have verified that in version 0.8 of Athena the exported norm(E) was the flattened data, provided that the flatten box was checked (of course). I have been unable to determine if I have any errors in the settings in version 0.9.24 but all parameters that I can find are identical in both 0.9.24 and 0.8. I have also uninstalled and reinstalled Athena 0.9.24 and the effect is still the same. Has anyone else noticed this problem? Is this a bug? Thank you, Jeff -- Jeffrey G.
