[FieldTrip] freq / time range for source analysis?

in an MEG experiment we tested the power difference (40-100Hz, 10
tapsmofreq) between two experimental conditions not averaging over time and
We found a nice significant cluster in the lower gamma range and in the
first half of the time range.
Please have a look at the two figures.
Fig a is the multiplotTFR of stat, showing only significant areas.
Fig b is the sum over channels of the significance mask giving the number
of significant channels at the corresponding freq/time point.
Now, we are not sure how to pick the time and freq range for a subsequent
Should we take the whole time/freq range in which any channel/time/freq
combination became significant? Or is it better to pick some center value,
also to increase power in the source analysis?
