[FieldTrip] questions about averaging/clustering tutorial

Hello Fieldtrippers -

Two unrelated questions about the averaging and clustering tutorials:

1) By the end of the averaging routine, there were only ~75 useful trials per condition left, which seems to be quite small to me. I understand that different studies will require different numbers of trials, but I was wondering whether you could go into a little detail as to why you chose to complete the study with (seemingly) so few trials.

2) In the cluster tutorial, you specify "cfg.clusteralpha = 0.05" and "cfg.clustertail = 0". If the tail is double-sided, wouldn't you want to use a cluster alpha of 0.025?

Thanks -

Elli Kanal
