I am doing research on ERP signals using visual stimulus. I am using BioRadio device SDK to get the ERP signals. I can obtain the time and values of the electrodes being used.
While going through ERPLAB tutorial, I see that while given an EEG.set file, it generates EVENTLIST using a set of 'event codes'. Would someone explain to me how to obtain such event codes ? Are they responses to go/no-go task during any visual stimulus ? Do I need to set flag as event codes for such responses to tasks ?
