Libisis is a suite of tools for analyzing neutron scattering data developed at the ISIS pulsed neutron source.
Libisis takes raw signals obtained from number of the neutron scattering instruments and transforms these data into neutron scattering data in the form of <math>S_N (detector_n ,\tau _f )</math> where <math>S_N</math> is the number of neutron counted by the detector, <math>detector_n</math> -- number of the detector and <math>\tau _f</math> -- the time of the neutron's flight to this detector.
These data then have to be processed by the Homer application, which transforms these data into the data in the form <math>S(detector_n,\epsilon)</math>, where <math>S</math> is now in a physical units (e.g. mb/Sr/Unit_cell or relative units, related to a white beam vanadium run) and the <math>\epsilon</math> is the energy, lost by neutrons in collisions.
In addition to raw neutron scattering data, LIBISIS and HOMER use number of instrument and experiment description and calibration data files to do their job properly. Technical description of these files and what these programs are doing can be found here.
LIBISIS has a Fortran core with a Matlab interface. Some applications, such as Homer, can be run as standalone applications. Libisis was primarily developed by Dickon Champion, Freddie Akeroyd, Pranav Amin, Toby Perring and Dean Whittaker.
