Dear Stefan,

Thanks for reporting these issues. Some of them are already known to us, but require time for fixing and implementing new features.

I take the occasion to say that anybody with Python programming skills is welcome to contribute and help with the development of Larch. Having a community of developers instead of always asking to one single person should be strongly considered.

There are still to much limitation in some parts of the code in larch for my data evaluation. I would need to quite some code into the project and I#m not a python programmer (yet).

Going back to your specific questions, here my two cents contribution.

Dear All, dear Matt, all tests were done on Macs (one M1 & one Intel) with the latest version your software & latest OS. 1. Read-In of spec files works, but only one file at once. Even if multiple files are selected

2. If one tries to load text-files it is possible to load data form multiple files as long as you don’t try to load also the reference spectra. If you load the reference also the read-in stopps at the transmission/fluorescence spectrum of the second file selected.

These are related to:

we create 3 different files in one go: - one spec like file - one simple text file with only a view columns - one hdf5 file (also all fluorescence data of all detector channels available) we don't write multiple scans in one file, because in the beginning hdf5 file access was limited to one program, so we were not able to write multiple scans during in-situ experiments and make online data evaluation best regards Stefan

Furthermore, with respect to an ASCII file, a Spec file may contain multiple scans, so it is impossible to know in advance which scan to select if one selects multiple Spec files to load.

To my opinion, when you need to read multiple data from many files, the simplest approach is to write a small python script (or Jupyter notebook) that reads the data and save them in an Athena project file or Larch session that you can then easily read back with xas_viewer.

I can further help with that.

3. Trouble, that I sometimes can’t unmount network volumes after reading from them, larch saved on local discs. MacOS claims that python has files open; no other python program running

I let Matt or somebody else reply on this point.

...

4. unable to save the data of one XAS-viewer while having two xas-viewer open.
