[Eeglablist] Question about resulting ERP

[Raechel Steckley]

I have isolated a very robust ERN in my ERPS (A negative deflection that 
typically occurs 80-100ms post-response.  However, the ERP occurs about 
20 seconds too late.  Does anyone have any suggestions I may have over 
looked in pre-processing that would cause this?  

Thank you,
