Hi Aowen,

Sorry for the trouble. I think you are seeing a “known but not-yet solved” problem. The Feffit Panel in Larix needs to have an experimental data set to show a simulated EXAFS spectrum. That should not be necessary, but it is for now to work around this bug.

This is on the list of things to fix, but I did not get to it before the most recent release.

Subject: [Ifeffit] Issue about plotting simulated EXAFS in Larix

Dear Matt, I am trying to simulate a theoretical EXAFS with a DFT calculated CIF file via Larix. I performed a FEFF calculation on the CIF file and imported a path to the FEFF fitting panel. However, I didn't get any results when I clicked

Dear Matt,

I am trying to simulate a theoretical EXAFS with a DFT calculated CIF file via Larix. I performed a FEFF calculation on the CIF file and imported a path to the FEFF fitting panel. However, I didn't get any results when I clicked on the "Plot Current Model" bottom. I get the following error message: TypeError: unsopported format string passed to NoneType.__format__. Could you please help me? Thank you in advance.

Best regards,

Aowen
