Dear all, The parameters in the matrix B are used to measure changes (modulations?) in the connections, compared to the reference condition, right?. The connectivity in the reference is modeled by A (appearing as 100% in the trial-specific effects) but A is two matrices, (forward and backward connections). What I would like to know is if these values in B indicate changes in the forward connections, the backwards, or is an estimate of the overall change in effective connectivity. In short, how to interpret the matrices B (for each one of the effects) in relation to A1 and A2? Thanks in advance. Best Jaime
