Hi Matt and all,
Unfortunately, after a clean install of larch following the source
installation instructions, I am not able export any fits to xdi files, and
a different error, shown below, is now printed in the terminal. Please let
me know if any additional information would be helpful in solving this
issue.
Thank you,
George

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.

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
