I have little familiarity with XES (or xraylarch, for that matter) so apologies if this isn't useful for your use-case - I'm sure some others will chime in with their respective tools, but I wanted to give a plug for the tool h5analysis (https://h5analysis.readthedocs.io/latest/index.html), which is maintained and developed by Teak Boyko and Patrick Braun at the REIXS beamline for this purpose, and which has some basic Larch integration features.

Hello,

I am new to the technique of XES and have been working out a way to analyze some XES spectra. I have used Larch in the past for XAS analysis and found a few places that indicated that larch is also capable of processing XES data in the LarchGUI application. I have been working to install a version or find how to do this and have not been successful. Have XES support been removed from the larch applications?

Any help or clarification is greatly appreciated! Thank you in advance.

Sincerely,
