[FieldTrip] Cluster-based permutation tests on single channel

The neighbours field is for defining adjacent channels for multi-channel multiple comparison correction. I'm not sure if you've gotten a response on this yet, but you simply set the cfg.neighbours field to be empty in your call to ft_freqstatistics for using cluster based corrections within time-frequency space for single channels.

cfg.neighbours = [];

I wanted to perform a Cluster-based permutation tests on time-frequency data, on a single channel (one Independent Component). But the ft_freqstatistics() function ask me for the "neighbours" field in the "cfg" structure, although I set the cfg.minnbchan to 0. Is there a way to run this analysis in a single channel?

Thanks a lot in advance!
