Hello, I have recently installed Demeter suite on my LinuxMint 20 machine with all required dependencies met. Athena works well and Demeter passed all tests during installation. When running Artemis however, there is an issue with fits that persists with provided examples any any other projects I open (including the ones done by colleagues and just re-run on my machine). After the fit (which completes fine and returns expected fit that looks ok when comparing it to experiment), when inspecting the log file, chi-square, reduced chi-square and R values are equal to 0 (example log file attached bellow). No errors accompany the fit. I am using Larch installed with anaconda, and Artemis uses Feff6 executable. I have re-installed Demeter and tried to get it to work with Ifeffit but the error persists. I have found an existing git hub thread dealing with similar issue (https://github.com/bruceravel/demeter/issues/62) but no solution that I could discern. Could it be an issue with my perl version (5.30.0)? If someone has any ideas what the issue could be and how to fix it, I would appreciate the help. Please let me know if I can provide any additional information, and I apologize if there is something obvious I may have missed. Sincerely, Ava -- Ava Rajh
