  Figure 1: Main flowchart. In the stimulus presentation plug-in, actions are defined for the BrainStream Matlab session as well as the client (see Figure 2).

At the start of the experiment, the speller is intialized on the client. The client then sends a marker to BrainStream to trigger the initTrain function. The advantage of this construction is that you are always sure that the stimulus client is correctly initialized before the actual experiment starts.
