This MATLAB script estimates the direction of coupling between two
oscillators.
Usage
The input data file should contain 3 columns (time, signal 1
and signal 2). The signals can be band-pass filtered (parameters of
filters should be adjusted in the script), then the phases are computed by
means of the Hilbert Transform. Finally, two directionality indices are
computed according to algorithms described Rosenblum et al. (2002).
