I've used Excel forever, but does the professional science world use it?ģ.
FITYK FOR MAC SOFTWARE
I've used Word and Excel for most of my labs, and occasionally LaTeX, but do professional biologists use MS Office? With that in mind, I'm looking for software recommendations for the following:ġ. Fityk plays a significant role in the fields of crystallography, chromatography, photoluminescence and photoelectron spectroscopy, infrared and Raman spectroscopy, and many others.As summer nears, I'm starting to get organized for my senior research project (bio and chem theses). You can also model zero-shift in your instrument or do more complicated refinement of the X scale. The program lets you fit multiple datasets together using common set of parameters. But it can also handle quite complex scenarios letting you define your own function types and specify sophisticated dependencies between parameters of the functions. The program can be operated with only a mouse when handling simple cases. The accuracy of nonlinear regression is verified with reference datasets from NIST.
FITYK FOR MAC SERIES
Fiyk also supports analysis of a series of datasets, automation of common tasks with scripts and embedded Lua for more complex scripting. It also allows graphical placement of peaks and auto-placement using peak detection algorithm. Fityk offers various nonlinear fitting methods, simple background subtraction, and other manipulations to the dataset. In other words, it is primarily peak fitting software, but can handle other types of functions such as data processing, and provides ergonomic graphical interface with a command line interface and scripting API. Fityk is usually bought by companies and institutions.įityk is a program for data processing usually experimental data, and nonlinear fitting of analytical functions especially peak-shaped. The program can be installed on many computers and can be also used after the end of subscription. The accuracy of nonlinear regression verified with reference datasets from NIST, an add-on for powder diffraction data (Pawley refinement), modular architecture, and an open source licence (GPLv2+).Subscribers have access to all versions of the program and to e-mail support. Manual, graphical placement of peaks and auto-placement using peak detection algorithm, various optimization methods (standard Marquardt least-squares algorithm, Genetic Algorithms, Nelder-Mead simplex), handling series of datasets, automation with macros (scripts) and embedded Lua for more complex scripting. Fityk has the following features for users intuitive graphical interface (and also command line interface), support for many data file formats, thanks to the xylib library, dozens of built-in functions and support for user-defined functions, equality constraints, fitting systematic errors of the x coordinate of points (for example instrumental zero error or sample displacement correction in powder diffraction). It is primarily used by scientists who analyse data from powder diffraction, chromatography, photoluminescence and photoelectron spectroscopy, infrared and Raman spectroscopy, and other experimental techniques and also used to fit peaks – bell-shaped functions (Gaussian, Lorentzian, Voigt, Pearson VII, bifurcated Gaussian.ĮMG, Doniach-Sunjic, etc.), but it is suitable for fitting any curve to 2D (x,y) data. Fityk is a program for data processing and nonlinear curve fitting.
