[FieldTrip] Granger causality

[Diego Lozano-Soldevilla]

Hi Eric,
I'll be relevant to you to know first how fieldtrip deals with plexon data:
http://www.fieldtriptoolbox.org/getting_started/plexon
This tutorial shows you how to read spikes and LFPs and cut them into
epochs for latter processing:
http://www.fieldtriptoolbox.org/tutorial/spikefield
I recommend you take a look to the following tutorial paper about Granger
causality (and other state of the art connectivity measures)
https://www.frontiersin.org/articles/10.3389/fnsys.2015.00175/full
You'll find the matlab code kindly supplied by the authors to reproduce all
the figures: you can explore it and try to adapt it to your reseach
question.
I hope that helps,
Diego
