I have a data set of resting MEG. I want to break it up into 3 second bins for analysis. I am using the EPOCHING part of preprocessing. However, I am consistently getting an error. I believe the problem is with trial definition, but it isn't clear to me how to manage that given that there are no triggers, or anything other than time to mark different "trials".
