About Demeter

Demeter is a comprehensive system for processing and analyzing X-ray Absorption Spectroscopy data.

Demeter is:

currently at version 0.9.26
available for linux, Windows, and Macintosh
a set of perl modules and related files
a programming tool -- it is the thing from which applications are built
free software, freely available from a git server
actively developed and maintained
in use by its author and users for real data analysis problems
a front end to Feff6, Larch, and Ifeffit (and, soon, Feff8)
the code base for Athena and Artemis
named for the Greek goddess of the harvest

Windows Installer & Updater

Download the 64 bit Installer package and double-click to install the Demeter system (version 0.9.26)

It's that simple! (Version 0.9.26 is an installer package, there is no updater package for this release and the documentation is included.)

I am no longer building 32-bit versions of the installer package. If you are unable to use the 64 bit installer, ask on the the Ifeffit mailing list and we'll see if something can be worked out.

Macintosh Installation

Carefully follow the Macintosh installation instructions.

Several common problems are discussed in the troubleshooting section.

Please report problems with the MacPorts package to the Ifeffit mailing list. Bruce does not own a Mac and cannot support Mac installation problems.

Frequently Asked Questions about Demeter, Athena, Artemis, and Hephaestus.
Lecture videos: In November 2011, I presented an XAS training course at the Diamond Light Source. All my lectures and software demonstrations were recorded along with the computer desktop. The Diamond technical staff did a great job assembling all of this material in streaming video. (There are other videos at that site, look for the ones with Bruce's name in the title.)
XAS Education: My collection of presentations that I give during XAS training courses. You can also find all the data used in the presentations and in the various videos linked above. PDF presentations are shown at my my Speaker Deck page. Here is a zip file with all the example data.
Programming documentation: This is the documentation embedded into each module which is part of the Demeter distribution. The PODs have been nicely formatted for html and organized into a structure that resembles a CPAN project page.
Demeter Programming Guide: The DPG is a how-to guide written at a higher level than the programming documentation. It includes descriptions of how to use the main components of Demeter as well as several complete examples.
Athena's new JSON-style project file. This allows a non-Demeter application to easily export data directly to Athena.
Demeter Changes list: The changes file for Demeter, Athena, Artemis, and Hephaestus. This version might be slightly more up-to-date.
Demeter To Do list: Bruce's "To Do" list for Demeter, Athena, Artemis, and Hephaestus. This version might be slightly more up-to-date.
