Dear Vladimir, Thanks for your previous answer. It was really helpful. I have now successfully specified and inverted the models and I am going throught the results. I could not find where the posterior means are stored in the DCM. When you see the results through the GUI [coupling (A)] you get the posterior means up and the propabilities down. I can find the propabilities under DCM.Pp.A but not for the posterior means. I tried the DCM.Ep.A but they do not match. Any suggestions where there are stored? Best wishes, Danai
