libdemeter-perl

Description

Demeter provides an object oriented interface to the EXAFS data analysis capabilities of the popular and powerful Ifeffit package and its successor Larch. Given that the Ifeffit and Larch APIs involve streams of text commands, this package is, at heart, a code generator. Many methods of this package return text. All actual interaction with Ifeffit or Larch is handled through a single method, dispose, which is described below. The internal structure of this package involves accumulating text in a scalar variable through successive calls to the various code generating methods. This text is then disposed to Ifeffit, to Larch, to a file, or elsewhere. The outward looking methods organize all of the complicated interactions of your data with Ifeffit or Larch.

This package is aimed at many targets. It can be the back-end of a graphical data analysis program, providing the glue between the on-screen representation of the fit and the actual command executed by Ifeffit or Larch. It can be used for one-off data analysis chores -- indeed most of the examples that come with the package can be reworked into useful one-off scripts. It can also be the back-end to sophisticated data analysis chores such as high-throughout data processing and analysis or complex physical modeling.
