Hi! Yeah, the visualization problem was just that, opening the 3D figure of the source map and visualizing the scouts. Thanks a lot and sorry for the trouble, as I said I am completely new with the software and a bit clumsy still.
With the source activity simulation however, there seems to be a problem, I don't know if i am doing something wrong too. I generated a 3 component signal with matlab and imported it to BS, then in Process user matrix clicked on run, simulate, full source maps from scouts. Here i selected the scout where i wanted to apply the signal ( in this example the Lateral Occipital R from Desikan killiani atlas) and clicked on Run. Here is an image with the result, in blue the scout and as you can see, the activity from the MRI view is pretty far from it.
