Toolbox for automated sorting of cellular calcium signals from optical imaging data.

| Watch this File

File Information
Description

This toolbox includes routines for using principal component analysis (PCA) and independent component analysis (ICA) to extract cellular signals from imaging data sets. A full description and validation of the method is provided in the paper, "Automated Analysis of Cellular Signals from Large-Scale Calcium Imaging Data," Neuron, 63:747 (2009): http://tinyurl.com/cellsort

UPDATE April 2013: Fixed a bug in function "tiff_frames" affecting performance in recent versions of MATLAB.

MATLAB release MATLAB 7.7 (R2008b)

The associated publication in Neuron 63, 747–760 makes this look promising. However, getting this to run based on the instructions provided in the supplementary publication is very trying for those with less than a mastery of Matlab.

These functions are well presented and a lot of care has gone into the code. Well worth a look. However, I have had trouble getting this to work reliably with my data since it has tendency to identify noise as the signal.
