Hi Folks, Larch 0.9.51 is now available for download and use. It's been several months since the last release, and there have been some important improvements to XAFS data processing and to the XAS Viewer application: - Parameters saved in an Athena Project File are now correctly saved and read into XAS Viewer (thanks Tyler Valentine!) - There is now a simple "Apply to all marked groups" feature for pre-edge peak fitting. That is, you can define a pre-edge peak model with one data set and then apply it to many others, either inspecting the individual fits or saving a CSV file with all the parameters and uncertainties for each fit to each data set. - XAS Viewer can now import multiple scans from a Spec file (thanks Mauro Rovezzi for help with this). It may seem that Specfiles are "legacy", but the reader should also be able to handle the ESRF Bliss HDF5 files (as read in with the silx package, from ESRF), which is their way of efficiently stacking multiple scans into a single binary file. While support for this here should be considered "beta" (or maybe "alpha"!), it is also reasonable to expect that this or a similar HDF5 format file will become a common way to collect and store XAFS data. - There are binary installers for Windows, MacOSX, and Linux. There are also now "GetLarch.sh" and "GetLarch.bat" scripts (that are very short) that can be run to do the download and install, essentially mimicking what the binary installer does. This may be useful for folks wanting to install Larch on multi-user servers or in existing (or "other") Python environments. This might also be useful for those who run into permissions issues, especially on MacOS, where installing a package from an untrusted source is often blocked by default. With the installer script, the unprivileged user is simply running a script that downloads a bunch of files and places them in the home folder. These scripts might also be useful for those who run into problems downloading very large files from millenia.cars.aps.anl.gov, as the installer scripts will use Anaconda and PyPI resources that are better distributed throughout the world. ... which brings me to a final note (I'll send out another message next week): The APS will have a planned power outage from April 30 to May 4 . This will take millenia.cars.aps.anl.gov off-line for those 5 +/- 1 days. That machine hosts the binary installers and also this mailing list. Mail sent to this list during that time will likely be lost (email routing servers can handle destination servers being down for a few hours, but not days). So, if you're planning on sending announcements here, either do it before April 29 or wait until May 5. If you have any questions, problems, or suggestions, please let me know. --Matt
Dear all,
tested the latest version on two Macs:
M1 on Big Sur
XAS viewer starts up, but the open dialog doesn’t work, it doesn’t open at all
old MacPro an 10.12.6
XAS viewer starts up, but the open dialog starts up, but I get a message, the he can’t read in the file or files. These file worked with the older version.
In both cases I started with an anaconda installation and made the update.
Matt, I can sent you more information.
Best regards
Stefan

Oh, I can definitely believe that there could be problems on M1 chips. I don't have access to one of these, at least not yet, so have not done any testing with that. I don't know to what extent the underlying python libraries are well-tested on M1 either. In some ways "XAS Viewer starts up" is an encouraging sign, but I don't know what might be going wrong from there. There isn't much you can do with XAS_Viewer without having read in some data, so it might be hard to test further.

Oh, can you send the files in question? There were changes in reading files that appear to be Spec files, but I think everything else should be the same. I don't think that OSX 10.12 is old enough to have "known problems".
In both cases I started with an anaconda installation and made the update.

Yes, that would be helpful. Thanks, --Matt
