[Ifeffit] Demeter: my new software project

[Anatoly Frenkel]

Bruce, first I thought you ran out of Greek goddesses names and tapped into
russian name book but then I googled Demeter and realized that she was a
Goddess of the Harvest. Nice name!

Subject: [Ifeffit] Demeter: my new software project



Hi!

I think that some of you will be interested in my latest XAS software
project, which I am calling Demeter.  Demeter is an object-oriented
programming interface to Ifeffit written in Perl.  It is intended to
encompass most of the current functionality of Athena and Artemis
while at the same time being more generalized, lower-level, and much
more robust.

In short, Demeter is not a software product.  Rather, it is the thing
that software products can be made from.

Demeter is targeted at a wide variety of XAS data analysis chores, such as

  * GUI's like Athena and Artemis.  In fact, I intend to rewrite
    Artemis using Demeter once I have incorporated enough
    functionality into Demeter.

  * A parser for feffit.inp files allowing you to translate your old
    analysis using feffit into ifeffit scripts and Artemis projects.

  * The analytic component of a high-throughput system such as those
    presented at the XAFS13 conference by the groups of Wolfram
    Meyer-Klaucke and Sven Schroeder.

  * The backend to specialized XAS software, like Shelly Kelly's mkfit
    program (http://www.mesg.anl.gov/exafs.html), or for ideosyncratic
    analysis like that described in Physical Review B, 73, p. 184121
    (2006)

There is still A LOT to do, but even at this early stage Demeter is
very useful.  In fact, Demeter can already be used for real data
processing and analysis.

Demeter is available on an anonymous Subversion server, so anyone with
an SVN client can check out a copy of Demeter at any time. Information
about Demeter and the Subversion server is at
   http://cars9.uchicago.edu/~ravel/software/demeter.html

You can browse the Demeter source code with your web browser at
   http://cars9.uchicago.edu/svn/demeter/

If this seems interesting to you, take a look at some of the short
example programs demonstrating Demeter's capabilities and economy of
language:
