Hello fieldtrip experts,

I decided to try multivariate granger causality today, using the steps in the tutorial 'analysis of sensor- and source-level connectivity'. I noticed that I am getting negative connectivity measures in the granger.grangerspctrm. Is this normal? If so, why does this happen?

I apologise if this has been asked before!
