Is re-referencing advised/necessary in my case? I was playing around with re-referencing to the average, and it really warps the waveform amplitudes compared to the ERPs calculated with our original methods. Any input would be helpful.</div><div><br></div><div>Thanks in advance,</div><div>Nick</div><div style="position:fixed"></div>
