Hi Jinghao,

If you are talking about only looking at a single channel and using those
for analyses, you can use cfg.channel for this purpose. It might be a good
idea as well to run through the respective tutorial, which can be found
at:  http://fieldtrip.fcdonders.nl/tutorial/cluster_permutation_timelock.
My previous suggestion will also aid in reducing small clusters popping up.
