Thanks Vladimir,

Using our approach works fine with static dipoles with
fixed moments. But simulating many datasets with different setting is
quite timeconsuming since I do want to run several simulations.

Thus the question is still how to simulate a multidipole dataset with fieldtrip,
maybe using a BEM headmodel.
