<div class="moz-cite-prefix">Dear Constantino,<br>
<br>
I'm pretty confused why you want to trick FieldTrip and put
timelock data into a frequency structure. You are aware that there
is a ft_timelockstatistics function that can cluster in time,
aren't you? Anyway, imho cfg.minnbchan defines how many
neighbouring samples another samples needs to have, and a timebin
can have max. two neighbouring samples, so it does not make much
sense here (and I think it really applies to channels only).<br>
<br>
The error you describe is because FT wants to compute neighbouring
channels, because you did not set cfg.avgoverchan='yes'. If you do
that, it will run through smoothly without an error. However, the
best way for you would be to write your own statfun by making a
copy of the statfun of your choice and modifying stat.stat to be 1
if the clustersize is < 10. That way, you could achieve what
you want. <br>
<br>
Best,<br>

I think cfg.minnbchan, applies also to time bins.
