I just noticed that I can compute the connectivity measures  
successfully even my model does not pass the Validation Tests. So if  
you are facing the same problem, just go the next step without  
bothering a lot. The most important things are Model Order selection,  
the selection of the window step and the window length.

Hope you the very best!
