sorry for bothering but I have a question regarding coherence.
I was planning on commuting coherence on my resting-state EEG data however, I have 256 electrodes and I was wondering whether I can do it by reducing the electrode space (so that I have for example group of FCz electrodes, group of Fp1 electrodes etc.). Is it possible to do it via Brainstorm? What would be the pipeline for that? It's my very early attempt to dive into connectivity, thus I'm lacking experience.
I would be very grateful for any help! And thank you!
