<DIV>Hi List</DIV>
<DIV> </DIV>
<DIV style="RIGHT: auto">I asked a question before about measuring EEG coherence by EEGLAB. I got benifits from the answer i got but still have something wrong. I applied the function to the same dataset provided with EEGLAB tutorial. i filtered the data first and then extract the epoches (153). After that i run ICA and ploted component cross-coherence between channel 4 and channel 9.</DIV>
<DIV>As you can see fig(1) was the result and i tried to zoom it in (fig 2).</DIV>
<DIV style="RIGHT: auto">I wanted to compare the result with that can be done by matlab function (Mcoher)<VAR id=yui-ie-cursor></VAR> and fig(3) represents<VAR id=yiv561490314yui-ie-cursor></VAR> the results i got.</DIV>
<DIV>My question is that, there is a big difference in the coherence's amplitude between the two functions where using EEGLAB the amplitude is less that 0.1 where with Mcohere as you can see is close to 1.</DIV>
<DIV> </DIV>
<DIV>I'm sure i miss undeerstand something because i'm new with this area and hope i can find some help from you .</DIV>
<DIV> </DIV>
<DIV>Cheers,</DIV>
