Hi Juejing, Oh, very sorry for the trouble... I have definitely seen something similar, but I think that is fixed in the development version. Can you send a Session file, and I'll see if I can make sure that is fixed for the next release (soon!)... On Sat, Aug 27, 2022 at 5:13 PM wrote:

Hi all,

I am using xas_viewer, version 0.9.65, to fit some XAFS data. In a typical situation I will also fit the coordination numbers of atoms by add customized variables in the amplitude boxes (image below). It works fine during my fitting.

However, when I save my result as a larch session and load it later, all my customized parameters are disappeared, and the amplitude boxes are reset. Therefore, I need to refill all the variables after each save & load cycle. This becomes increasingly tedious when dealing with about 20 different paths. Is there any workaround of this problem?

Best,
