This package performs time-varying connectivity analysis on a simulated data and an EEG sample obtained from EEGLAB toolbox. Two time-frequency methods (short-time approach as well as Adaptive AR modelling) have been utilized to extract time-varying Partial Directed Coherence (PDC) and Directed Transfer Function (DTF) from the underlying signals. All scripts are easy to use, as they are heavily commented. The package is associated with the following reference:

It is notable that the slightly altered versions of some functions from BioSig Toolbox (http://biosig.sourceforge.net/) and ARFIT toolbox (http://www.gps.caltech.edu/~tapio/arfit/) have been used in this package. Please visit their websites for more details about their copyright licenses.
