[Eeglablist] Time frequency analysis

[Scott Makeig]

Andrew -

You are trying to create a spatial filter. There are many types. A simple
channel average filter is easy to compute, but it is not very spatially
specific as to the brain areas it is sensitive too. To do that, I'd
recommend you'd try using beamforming or ICA filters trained on your data
to pass only signals from specific locations or processes in the data.
