Not sure whether epoching is correct because the amplitudes are incredibly high #6

did you add a rejectargument to the Epochs call whetn extracting the segments? Could be just an outlier containing some kind of artifact we haven't controlled for jet. You could control for outliers later in the analyisis. I dont think its to bad for now.

you mean something like this?:

reject = dict(grad=4000e-13, # T / m (gradiometers)
              mag=4e-12, # T (magnetometers)
              eeg=40e-6, # V (EEG channels)
              eog=250e-6 # V (EOG channels)
              )

yep, you only need the eeg part really. We don't have mag and grad. Here you would be rejecting peak-to-peak changes of 40 µV.
