Thanks Matt for the thorough explanation.

Actually it was Jamie Sethian who asked. I am working on using Larch as a code basis for doing high-throughput NEXAFS analysis. You can imagine automating just basic normalizing and background subtraction steps would be invaluable in this case. I am working with CAMERA ( Alex Hexamer, Ronald Pandolfi ) on making a GUI and Materials Project ( Patrick Huck ) along with ALS ( Alpha N'Daiye ) to have some sort of database contribution route. Data is coming from ALS beam line 6.3.1.

Yes, this is exactly the sort of thing Larch is meant to do!

I will be calling on you as I learn Python concurrently with implementing Larch. For example, I got read_ascii to work but couldn't get the plot functions to work and get "newplot not defined." I am using 2.7 on Mac OSX El Capitan. Any ideas?

Do you have wxPython installed and get the other dependencies (including wxmplot) installed? FWIW, I run it on a Macbook with El Capitan all the time, and have seen many successful installs with Anaconda.

If you are using Anaconda python on OS X, there is a weirdness with wxPython that requires using "pythonw" instead of "python" as the interpreter (some Framework thing), but that "just" makes running larch from a command-line or script fail immediately with a message about not being able to draw to the screen. The "larch_makeicons" makes mini-Apps that avoids this, and the next version will fix this even for the commandline programs.
