[Eeglablist] ERSP of pre-stim data

[Cedric Cannard]

Hi,

You will need epochs containing data before -1000 to be able to compute ERSP on [-1000 0] ms (e.g. [-1500 +500] ms).

See this discussion with Andreas Widman on causal filtering for pre-stimulus analyses: https://sccn.ucsd.edu/pipermail/eeglablist/2021/016161.html
