[Eeglablist] time frequency averaging

[Brian Roach]

I have used the channel time frequency plot option in EEG lab to get ERSP 
and ITC.  It would be useful for me to be able to use this function across 
groups of subjects.  I imagine that this is possible, but I am unsure how 
to proceed.  I know that I could use the merge function to join datasets, 
but I am looking at a dataset where only epochs with correct responses are 
of interest, so merging would allow a subject who responded correctly more 
to have a larger influence on the grand average - this is not what I 
want.  Does anyone know how to do this?  An example EEG.history script 
would be great.
thanks,
Brian
