[FieldTrip] granger causality on beamformer data

[Tyler Grummett]

?Hello fieldtrippers,


I was just wondering whether it would be sensible to do granger causality on all 1400 virtual channels, as calculated using beamformer.


Or should you do a PCA reduction of some description beforehand.


I was also wondering how to create regions of interest. Some of my colleagues think that we should use some kind of spatial ICA technique.


Im open to all suggestions.


Tyler
