options for cluster-based permutation tests

Hello dear people,

I have a very quick question that hopefully has not been answered before:
we have to run cluster based permutation tests using clustering in time
and frequency but not in space. Which means not considering neighbor

I think that the best option would be using the parameter

cfg.neighbourdist    = 0.0;

which means that there are no neighbor electrodes.

Is that correct or is there a better option? Should cfg.minnbchan be
changed as well and set to 0?

the whole lists of config parameters passed to freqstatistics() would be:

cfg = [];
cfg.channel = choi;
cfg.method = 'montecarlo';
cfg.statistic = 'depsamplesT';
cfg.tail = 0;
cfg.alpha = 0.05;
cfg.numrandomization = 5;

cfg.clusteralpha = 0.05;
cfg.clusterstatistic = 'maxsum';
cfg.minnbchan = 0;
cfg.clustertail = 0;
cfg.neighbourdist    = 0.0;

thanks in advance for your help

best regards
