I want to compute the average and then difference of the ERP components using the pop_comperp() function in EEGLAB but I realized that I have some issues with the signs. The ERP data for some components are flipped and therefore the average is not correct. Below you can see my output plot.

Do you know how can I solve this problem?

Kind Regards,
