Frida - Flexible rapid interactive data analysis
frida
Frida is software for scientific data analysis, primarily written for inelastic neutron scattering. Its data model is quite generic (data files consist of x-y-dy tables that are differentiated by z coordinates), so that it can be used for many different kinds of observational data.

Frida1, written in FORTRAN, was developed in the 1990s. The original name IDA was changed to Frida just because there were too many other open-source projects all called IDA.
Frida2 is a rewrite in C++. It is the standard tool for data analysis at the backscattering spectrometer SPHERES. The more specific routines for time-of-flight spectroscopy are currently being ported from Frida1 to Frida2, so that Frida1 can be phased out by mid-2010.
Frida1 includes raw data reduction routines for numerous backscattering and time-of-flight spectrometers. These routines are not ported to Frida2, but to the separate raw-data reduction package SLAW: http://iffwww.iff.kfa-juelich.de/~wuttke/slaw/.
