IFEFFIT: Interactive XAFS Analysis

SEE: New IFEFFIT Web Page

IFEFFIT is an interactive program for XAFS analysis. It combines the high-quality analysis algorithms of AUTOBK and FEFFIT with graphical display of XAFS data and general data manipulation.

IFEFFIT comes as a command-line program, but the underlying functionality is available as a programming library. The IFEFFIT library can be used from C, Fortran, Tcl, Perl, and Python. This allows a variety of user interfaces (both graphical and non-graphical) to be written around IFEFFIT. There are several graphical user interfaces using the IFEFFIT library, including ATHENA, ARTEMIS, and SIXPACK. IFEFFIT and these GUIs are under active development, but are fairly well tested and ready for use.

Credits:

IFEFFIT was developed by Matt Newville at CARS, the Consortium for Advanced Radiation Sources, at The University of Chicago. Funding comes from the US DOE. IFEFFIT borrows many ideas and some code from the UWXAFS Project of the University of Washington.

Several other ideas, including the Fast Fourier Transform, non-linear least-squares fitting, the EXAFS path expansion, and eval() were taken from the wide range of publicly available resources that existed in a time before ideas were termed 'intellectual property'.

The IFEFFIT web page is hosted at CARS.
