![]() If fityk is not installed on your compter then the command 'dpkg -L fityk' will give followin dpkg -L fitykĭpkg-query: package 'fityk' is not installed This will update the list of newest versions of packages and its dependencies on your system.Īfter downloading the latest package list with the help of above you can run the installation process. Libjs-sphinxdoc is necessary for the Javascript stuff in the documentation.Ībove command will download the package lists for Ubuntu 16.10 on your system. Variable, can be the same as the width of another peak or can be givenīy a complicated - common to all peaks - formula. the width of a peak can be an independent Of the program is flexibility - parameters of peaks can be arbitrarilyīound to each other, eg. Other fields, since concepts and operations specific for crystallography areįityk offers various nonlinear fitting methods, subtracting background,Ĭalibrating data, easy placement of peaks and changing peak parameters,Īutomation of common tasks with scripts, and much more. It was developed for analyzing diffraction patterns, but can be also used in Other words, for nonlinear peak separation and analysis. Various optimization methods (standard Marquardt least-squares algorithm, Genetic Algorithms, Nelder-Mead simplex).manual, graphical placement of peaks and auto-placement using peak detection algorithm.fitting systematic errors of the x coordinate of points (for example instrumental zero error or sample displacement correction in powder diffraction).dozens of built-in functions and support for user-defined functions.support for many data file formats, thanks to the xylib library.intuitive graphical interface (and also command line interface).to fit peaks – bell-shaped functions (Gaussian, Lorentzian, Voigt, Pearson VII, bifurcated Gaussian, EMG, Doniach-Sunjic, etc.),īut it is suitable for fitting any curve to 2D ( x, y) scientists who analyse data from powder diffraction, chromatography, photoluminescence and photoelectron spectroscopy, infrared and Raman spectroscopy, and other experimental techniques.Fityk is an open-source program for data processing and nonlinear curve fitting, that works for Windows, Linux and macOS.General-purpose nonlinear curve fitting and data analysisįityk is a flexible and portable program for nonlinear fitting of analyticalįunctions (especially peak-shaped) to data (usually experimental data). automation with macros (scripts) and embedded Lua for more complex scripting.the accuracy of nonlinear regression verified with reference datasets from NIST.an add-on for powder diffraction data (Pawley refinement).Linux: Debian, Linux Mint, MX Linux, Arch Linux, Ubuntu, Fedora, and openSUSE.Candidate for moving: This page should be moved to Applications/OtherApplications.Universe (community maintained) repository Main (officially supported) Ubuntu repository, not installed by default Those installed by default are in Main (officially supported) Ubuntu repository. For information about the Ubuntu repositories see Repositories. Clicking on the icon next a program should take you to information about the Ubuntu package.īIKA - A laboratory information management system (LIMS) built on top of Zope and Plone, and coded in Python.įityk - A curve fitting and data analysis program, specialized in peak fitting.īumblebee - A system for managing instruments and other resources (e.g. analytical equipment) that must be shared between a number of users. G3data - "g3data is used for extracting data from graphs. g3data makes the extracting process much easier." In publications graphs often are included, but the actual data is missing. A step by step installation guide can be found here: (Post by Chickenmonger) Intel Fortran Compiler 9.0 for noncommercial, nonacademic use. G95 - The goal of the g95 project is to create a free, open source Fortran 95 compiler and runtime libraries. PLplot - A powerful 2D and 3D scientific plotting library with C, C++, Fortran, Java, Python, Perl, Octave, and Tcl interfaces. Device plugins include X, wxWidgets, Gnome Canvas Widget, and Tk GUIs as well as Post Script, PNG, JPEG, and GIF file devices. ![]() GNUplot - A command-line driven 2D/3D plotting tool. ![]() Can perform data fitting and exports to PNG, PS, Xfig, and LaTeX formats. Has python bindings (python-gnuplot) for including in other programs or scripts. ![]() Plotdrop - A minimal GNOME front end to GNUPlot. Gnuplot tips (not so Frequently Asked Questions).
