Dear all, I recently performed FEFF calculations to model chi(k) spectra. The generated chi.dat files had chi(k) data starting at 1.4k. When importing the data (chi.dat) in Athena (version 0.8.056) using IFEFFIT 1.2.11 (XP OS), Athena was not able to interpolate the data from 0 to xk (x being the starting k value of the file, in my case 1.4). Thus Athena could only read the data in but no changes were visible in the plot window when changing parameters (e.g. k-weight, looking at the FT). The plot window just froze. Yet the echo and Ifeffit buffer indicated that the changes had been taken into account. I tried to uncheck the buffering and storing options in the plot window without success. In contrast, with the newest version of Artemis (i.e. 0.8.012, or previous versions of Athena, e.g. 0.8.054), I was able to read and play with any chi data. To look at the data in Athena 0.8.056 I simply added a 0-1.4k interval with a 0.05k grid and set chi(k) to 0 in this interval. Do you also experience this tiny Athena 0.8.056 (XP OS) bug? Or is there a workaround?
