Dear SPMers,
We have done some ERP preprocessing by using SPM8. We found that strangely the baseline of waveform is not equal to 0. In attached you can see that the baseline of Fz is around 1 uV; while the baseline of PO5 is around -2 uV. Could anyone give us some suggestion in resolving such a problem? Many many thanks!
Bests,
Sun Delin
