MSGranger

matlab toolbox to compute time-varying frequency-specific Granger-causality

Our matlab toolbox for Multiscale Granger Causality is available here ! Version 0.502, 24 July 2019

  1. Download and unzip MSGranger.zip
  2. Add the whole directory in your path
  3. Try it using the MAIN.m script and check additionnal information on the README.txt file
  4. You are there ! You should obtain a graph like the one below
