Dear Bruce and IFEFFIT community, Hope all is well. I found a bug with Athena's file export function. I had two normalized mu(E) data with very similar spectra but different x-axis values (collected with different energy step settings). [image: image.png] When I batch exported them to a .dat file using the purple E button while "Save next plot to a file" was turned on, the resulting data only had a single x-axis column, which was taken from the first data. Hence, when I plot the two spectra from this .dat file, they now look different: [image: image.png] If I export each data individually to .dat files, then they are correct. [image: image.png] I'm attaching the Athena project file containing the two data and the .dat files I exported, both together and individually. Please let me know if anything is unclear. Thank you in advance for your help. Best, Soyoung Kim
