[Eeglablist] storing and processing averaged data in EEGLAB

[Darren Weber]

What is the best way to calculate and process ERPs in EEGLAB?

If I want to convert an epoch dataset to an ERP dataset, should I simply
change EEG.data to an Nchan x Nsamp matrix?  For example:

EEG.data = mean(EEG.data, 3);

Can we store the variance somewhere?  Do we have a data structure separate
from EEG.data, maybe EEG.avg that contains the mean, var, Ntrials or Nepochs
in the avg, etc?  What is the best way to combine ERP data across subjects?

Best, Darren

PS, I can do all this with custom scripts, but I want to know if there is a
specific EEGLAB way of doing all this.
