fityk - non-linear curve fitting and data analysis
This manpage documents briefly the fityk
nonlinear fitting of analytical functions (especially peak-shaped) to data
(usually experimental data). In other words, for nonlinear peak separation and
It was developed for analyzing diffraction patterns, but can be also used in
other fields, since concepts and operations specific for crystallography are
separated from the rest of the program.
Fityk offers various nonlinear fitting methods, subtracting background,
calibrating data, easy placement of peaks and changing peak parameters,
automation of common tasks with scripts, and much more. The main advantage of
the program is a flexibility - parameters of peaks can be arbitrarily binded
with each other, eg. width of peak can be an independent variable, can be the
same as width of other peak or can be given by complicated - common for all
peaks - formula.
The program comes in two versions: fityk
, the GUI version and
, the command line version.
