Neurophotonics tutorial on making connectivity diagrams from Channelrhodopsin-2 stimulated data Lim, Diana; LeDue, Jeffrey; Murphy, Timothy H


This package of sample data and matlab codes will process, filter, and average raw voltage sensitive dye images, generate a comprehensive connectivity matrix and a network diagram (as seen in Lim et al., 2012, 2014).

Requirements: Matlab (with Bioinformatics Toolbox and Brain Connectivity Toolbox)

Inputs: sample data; Matlab functions; Mask.tif (as included in .zip file)

Outputs: dF/F0(%) VSD connectivity matrix; Figure of network properties as a function of threshold levels; Network diagram

To use this package: Unzip data files and ensure all Matlab functions are in the same directory as the NetworkAnalysis_VSD.m Open NetworkAnalysis_VSD.m with Matlab In NetworkAnalysis_VSD.m, enter the folder name where the data is stored (line 5) Execute code.
