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
channels.
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.correctm='cluster';
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
