Toolbox for analysing FCS/FFS data with array detectors

BrightEyes-FFS

A toolbox for analysing Fluorescence Correlation Spectroscopy (FCS) and Fluorescence Fluctuation Spectroscopy (FFS) data with array detectors. The fcs module contains libraries for:

• Calculating autocorrelations and cross-correlations of raw FCS/FFS data (i.e. photon counts vs. time or photon arrival time traces). Supported file types include .h5, .ptu, and .czi.
• Fitting correlations to various 2D and 3D diffusion models
• Calibration-free FCS/FFS analysis such as circular-scanning FCS and pair-correlation analysis
• Miscellaneous tools

The fcs_gui module contains libraries for:

• Storing and loading FCS/FFS analysis sessions, as used in the GUI

The pch module contains libraries for:

• Calculating photon counting histograms
• Fitting histograms with Fluorescence Intensity Distribution Analysis (FIDA)

The tools module contains libraries for:

• Fitting various models to data (polynomial, Gaussian, power law, etc.)
• Stokes-Einstein relation
• Save/load 2D arrays to/from .csv files
• Save data to .tiff file
• Miscellaneous tools

GUI

For quick and common types of analysis, you can use the GUI (https://github.com/VicidominiLab/BrightEyes-FFS-GUI), which contains most of the basic features. In addition, there is an automatic Jupyter Notebook writing tool to convert an analysis session started in the GUI to a Notebook.
