Description
QtiSAS [1, 2] is an open-source cross-platform software designed for the graphical visualization, reduction, analysis, and fit of data. At Jülich Centre for Neutron Science (JCNS) it is designed particularly to work on data produced by small-angle neutron scattering (SANS) instruments, however it could also be an alternative to proprietary scientific software like Origin or Igor Pro.
QtiSAS has following SANS tools:
- DAN is SANS data reduction interface which allows to define a new or modify an existing data-reduction-protocol inside of the running program.
- ASCII.1D is powerful import/export tool for the radial averaged SANS datasets that allows conversion to other SANS-presentation (Guinier, Zimm, Porod, etc), data filtering, arithmetic operations.
- SVD is singular value decomposition. Scattering curves of a multicomponent system measured by applying a set of the scattering contrasts could be decomposed to the individual scattering functions and corresponding cross-terms.
- Fit.Curve(s) is the fitting interface which allows to a user to fit radial averaged datasets taking into account polydispersity of any parameter of a fitting function and/or the instrument resolution.
- Fit.Compile is user-friendly interface to create and compile a fit function of any complexity using custom C++, but there is also an option of calling of FORTRAN functions.
