I have used *spatio_temporal_cluster_1samp_test* on my time-frequency data
(power (EpochsTFR) with a shape:[epochs X chan X freqs X time] ). I have
read the cited paper (MarisOostenveld07) for the permutation tests.
However, it is still not clear to me what these functions are exactly doing. I
have confused about the cluster analysis after seeing my plots. I have
attached parts of my code and my results to this email.

The first row shows the power activities and the second row shows the
p-values of the cluster analysis (red points are significant points). I
would be thankful if someone can give me some general explanation of these
functions. Is it normal to see a high non-significant activity and low but
significant activity based on the permutation cluster analysis?
Did you look at the statistics image that get thresholded ?
I doubt any of us has the time to edit your script to test it on a public
dataset. Can you try to make a minimal example that uses a public
dataset shared with MNE?
