GW6 - Grand-average ERP algorithm

GW6 algorithm for multichannel EEG data

This is the Matlab implementation of the algorithm presented in W. Giroldini, L. Pederzoli, M. Bilucaglia et al., A new method to detect event-related potentials based on Pearson’s correlation, EURASIP Journal of Bioinformatics and System Biology, 2016:11.
In this paper, a new method called GW6 is proposed, which calculates the ERP using a mathematical method based only on Pearson’s correlation. The result is a graph with the same time resolution as the classical ERP and which shows only positive peaks representing the increase—in consonance with the stimuli—in EEG signal correlation over all channels.
