Project Activity See All Activity > Categories Chemistry, Information Analysis, Physics, Visualization License GNU General Public License version 2. This free software was originally developed by Marcin Wojdyr. The program's installer files are generally known as cfityk.exe or fityk.exe etc. This download was checked by our built-in antivirus and was rated as clean. It is specialized in fitting peaks (bell-shaped functions like Gaussian, Loretzian, Pearson7, Voigt) to experimental data. Fityk is developed for Windows 2000/XP/Vista/7/8/10/11 environment, 32-bit version. It operates either as a command line program or with a graphical user interface. Fityk is nonlinear curve-fitting and data analysis software. It runs on Linux, macOS, Microsoft Windows, FreeBSD and other platforms. įityk is distributed under the terms of GNU General Public License, but since version 1.0.0, subscription is required for downloading binaries. It is also used in other fields that require peak analysis and peak-fitting, like chromatography or various kinds of spectroscopy. ![]() Originally, Fityk was developed to analyse powder diffraction data. It is possible to either change a single point or apply a transformation to all points. These properties can be changed using symbols X, Y, S and A, respectively. It is positioned to fill the gap between general plotting software and programs specific for one field, e.g. Every data point has four properties: x coordinate, y coordinate, standard deviation of y and active/inactive flag. Fityk is a curve fitting and data analysis application, predominantly used to fit analytical,īell-shaped functions to experimental data.
