<DIV>I'm dealing with my EEG data. I want to run some cross correlation and coherence on them. The problem is:<BR>1. which reference method will you advise me to choice? my data is reference to the vertex(Cz), i don't know whether it's ok, seems most of you choose the average between left and right mastoid.</DIV>
<DIV>2.IF we will do rereference,it's guided in the m-file 'ft_preprocessing' that we might configure our inputs as<BR>"% cfg.reref = 'no' or 'yes' (default = 'no')<BR>% cfg.refchannel = cell-array with new EEG reference channel(s)<BR>% cfg.implicitref = 'label' or empty, add the implicit EEG reference as zeros (default = [])<BR>% cfg.montage = 'no' or a montage structure (default = 'no')"<BR>then, what's the difference between "reref" and "montage"?<BR> Is the montage structure a matrix, and how it defines?If I modify my data to an average rereference, how will be the input configured?</DIV>
<DIV><BR>Best,</DIV>
