See below the changes in each version:. It operates either as a command line program or with ftiyk graphical user interface. October 17, GPLv2.

The utility allows users to execute vityk script, use data point ‘Transformations’ or adjust the preferred ‘Functions’, with the possibility of choosing between a wide range of options, such as ‘Quadratic’, ‘Cubic’, ‘Gaussian’, ‘Lorentzian’, ‘EMG’, ‘Polyline’, ‘ExpDecay’, ‘Voigt’, ‘Spline’, ‘DoniachSunjic’ and many more, while also letting users create their own.


On Fitjk fitting was very slow, this was fixed. The tool allows users to exclude inactivate points from fitting operations and work with several datasets simultaneously. Originally, Fityk was developed to analyse powder diffraction data. It is aimed at experimental data resulted from a variety of domains, like chromatography, spectroscopy, crystallography and many others.
