Chunliang,

What is the code in your version of createVec.m at 757?
Is it:
try
trialminimum=trialcountminper;
catch
trialminimum=trialcountmin./sum(tce>0); %Only count
event-related effects
end


Is this a block design or an event-related design?

If you are using a block design, this shouldn't be an issue.
