What's new in Demeter?

New graplical toolkit

I am now using a graphical toolkit called wxWidgets that brings a much more professional and polished look to the GUIs. Among many advantages, wxWidgets always takes on a native look and feel. So on Linux, Athena will look like a Linux application and on Windows, it will look like a Windows application.

New plotting tools

I am now offering an alternative to the ugly old PGPLOT plotting. It uses Gnuplot, which makes much more attractive and feature-full plots. The GUIs also offer more kinds of plots and more control over how the plot gets made, all while still being quick, easy, and well-suited to the task of plotting XAS data.

New data processing and analysis features

The new Athena is much the same as the old Athena, although with a facelift. The new Artemis offers lots of new and interesting stuff, including:

• A revamped, more fully featured path-finder in Feff
• More bells and whistles in Atoms
• Various path abstractions which allow for more power. more flexible fitting models and more interesting plots
• More things are visible on the screen at once -- it is now possible to see a path page and the GDS page at the same time. Drag-n-drop is used extensively to move paths and other things around on screen

Here are a few screenshots of the new Athena and here are some screencast videos demonstrating the use of the new Artemis

A complete programming interface

This allows you to write your own scripts and programs using the exact same algorithms as in Athena and Artemis.

Some backwards compatibility

Athena project files are unchanged and can move between the old and new versions of Athena. Old-style Artemis project files can be imported (albeit with limited success at this time) into the new version of Artemis.
