Hi George, Hm, sorry about that. It seems to be saying that the parameter uncertainties weren't calculated correctly. It probably should not even be trying to estimate the uncertainty in the model. I believe it should be fixed in git master for larch, and I'll see about looking for this in lmfit too. On Mon, Apr 20, 2020 at 4:00 PM George Sterbinsky < GeorgeSterbinsky@u.northwestern.edu> wrote:
Hello,
When attempting to export an xdi file for a pre-edge peak fit in XAS viewer, the error message below prints to the terminal and the xdi file is not generated. I can provide the project file and instructions for generating the error message if that would be helpful.
Thank you, George
