Hi Stefan,

Very sorry for that. This will be fixed in the next version, which I'm
hoping to get out in the next week or so.

[Ifeffit] Larch 0.9.59, problems with PCA

2022-05-10 Thread Mangold, Stefan (IPS)
Dear all,

on 2 computers (Mac, Intel and ARM, newest version operating system) the PCA 
does not work. If I press "Build Model with selected groups“ on both computers 
and several different datasets, I only get „training model“ and nothing else 
happens. Absolutely nothing else changes within this tab inside XAS viewer.

Best regards

Stefan Mangold

[Ifeffit] Larch 0.9.59

2022-04-01 Thread Matt Newville
Hi Folks,

Larch version 0.9.59 has been released.  It should now be installed by
default using all installation mechanisms, and you may see a notice to
update if running xas_viewer.

This is mostly bug fixes, but some are important enough to warrant pushing
out now.  Changes are detailed at
https://github.com/xraypy/xraylarch/releases/tag/0.9.59

For XAS Viewer use, the most important of these are
 a)  "energy reference" and "energy shifting" of spectra work much better.
 b) the action of the "pin icon to select points on the graph" has now
changed (by popular opinion) to be: click on pin icon, *and then* cliick on
point of the graph.

There are also new binary installers - the one for Linux might work for
more people ;), and the installation might be faster for more people.

We're hoping that there will be another release in a couple of months to
give a more comprehensive "Project File" concept.   But, as always,
suggestions or comments are welcome.

Cheers,

--Matt
