Dear Donald,
"Based on this recent simulation, a target of 30 trials seems reasonable." means that, to get significant activation in a SINGLE SUBJECT, right? Actually I care more about significant group activation and I also wonder how many subjects should I collect if (1) in one event-related study, an EV has 16 repetitions and (2) in another study, an EV has 32 repetitions. Should the number of subjects in (1) double that in (2)?
