[FieldTrip] Extracting a timecourse from cluster of channels

I am using fieldtrip's cluster-based permutation test to identify a
significant channel-time cluster showing an effect.  Now I would like
to extract a timecourse averaged over these channels (for the purpose
of comparing different conditions, not used to generate the cluster),
but I'm not sure if it makes sense to do so because the channels
belonging to the cluster change over time -- would the timecourse have
contributions from different channels at different time points?  Do I
need to limit my cluster to fixed channels across time? (And if so,
how do I do that?)
