Hello Everyone!

We have two models, one basic and one with RT entered as a parametric
regressor. Would it be legitimate to create a set of DCMs with VOIs from
both of these models? The only difference between the two models are the
parametric regressors. We looked at a timeseries taken from the same
coordinates in each model and found a small difference (mean = 1.3, std =
.07). Would a better alternative be to use coordinates found in the RT model
to extract a VOI from the basic model, thereby having all the VOIs come from
the same model?

thanks very much for your time and effort!
Nick
