#FITTING BASLEINE WITH FITYK SOFTWARE#

The data provided herein was used to generate the figures in DiameterJ: A Validated Open Source Nanofiber Diameter Measurement Tool, where more discussion can be found. Originally, Fityk was developed to analyse powder diffraction data.

It is positioned to fill the gap between general plotting software and programs specific for one field, e.g. Additionally, DiameterJ’s raw output files, and processed data is included for the reader. Fityk is a curve fitting and data analysis application, predominantly used to fit analytical, bell-shaped functions to experimental data.

In this article, all digital synthetic images, SEM images, and their segmentations are included. Yet, writing the very same commands in command window leads me to different result - it looks like the first fit was not frozen automatically and. With Auto-Freeze it does work fine - I have both Lorentzians properly fitted. Once validated, DiameterJ was used to analyze SEM images of electrospun polymeric nanofibers, including a comparison of different segmentation algorithms. guess Lorentzian - fit - activate one region where the small peak is - add a baseline - guess Lorentzian and fit. DiameterJ was validated with 130 in silico-derived, digital, synthetic images and 24 scanning electron microscope (SEM) images of steel wire samples with a known diameter distribution. 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. There are also people using it to remove the baseline from data, or to display data. Fityk is specialized in fitting peaks (bell-shaped functions like Gaussian, Loretzian, Pearson 7, Voigt) to experimental data.

These files include the images that were analyzed, the data to create histograms of fiber radius, pore size, fiber orientation, and summary statistics, as well as images to check the output of DiameterJ. Fityk is an open source app for nonlinear fitting of analytical functions (especially peak-shaped) to data (usually experimental data). DiameterJ produces ten files for every image that it analyzes. DiameterJ is an open source image analysis plugin for ImageJ.
