Hi Gang,

Well the 8 block are assumed to yield different brain activation otherwise I would have simply pool them together. It's a learning experiment so I want to see how changes occur in the brain across those blocks.

1- So was I correct to say that each trial in the stimfiles get it's own covariate (different for each trial)?
2- Also, should I use the 'real' RT or the RT 'minus' the mean, as in other programs (3dMEMA, 3dttest+++)?


thanks,
