<div dir="ltr">Dear all,
<div><br>
</div>
<div>I'm using fieldtrip to do dynamic EEG connectivity analyses and I have a few questions about trial averaging in ft_connectivityanalysis. I realized regardless which method I'm using, the ft_connectivityanalysis tends to averaging over trials (dimension
rpt), which sacrifices the dynamic of the data. Is it possible not let the function averaging over trials while still getting a meaningful result? ( I tried to duplicate trial and let it average itself and it reported some errors.) Or is there a connectivity
method that allows non-trial-averaging to run? Thank you very much! </div>
