Re: [Ifeffit] found some issues found in larch (read-in issues)
Hi Stefan, Thanks, that's all very helpful. As Mauro says, some of these might be known already, but I'm not 100% certain of that.

Reading in spectra from Spec files, Athena Project files, and other "multi-spectrum files" would potentially be a bit more complicated -- which spectra from which file would you need? I guess we could assume "every spectrum", but with a Spec file, you still need to select columns.Maybe you have more uniform Spec files than the ones I normally see, but I'm not sure I know that "read every scan from multiple spec files" would be reliable. To be clear, I'm completely fine with *trying* to read in as many types of "data directly from beamlines" as possible, while also recognizing that this is a bit of a moving target and admitting that some data formats might have higher priorities than others. For sure, trying to better support HDF5 and NeXuS is a priority. > 2.

I'll investigate. As Mauro says, it might be related to another "known problem", but that doesn't mean it is completely solved ;) . > > > 3.

As Mauro says, I think we may have seen and solved this one. But, if you have error messages or further information on what you see when this happens, that might be helpful. --Matt ___ Ifeffit mailing list Ifeffit@millenia.cars.aps.anl.gov http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit Unsubscribe: http://millenia.cars.aps.anl.gov/mailman/options/ifeffit

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. > > On 26/10/2022 11:46, Mangold, Stefan (IPS) wrote: >> Dear All, dear Matt, >> all tests were done on Macs (one M1 & one Intel) with the latest version >> your software & latest OS. >> 1.

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

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.
