[Eeglablist] Strange Displacement in ERP Images

[Mikołaj Magnuski]

Hey,
it looks like you did not perform baseline correction, am I correct?
Baseline correction is a simple form of detrending - for each epoch it
removes the mean from a specified part of the epoch from the whole epoch.
You can find this option in edit or tools (I don't remember, but there
should be an info on EEGlab wiki) --> 'remove baseline'.
