Hello Martin, thank for your answer. Can you please point me to an example of such blocks from which I can take inspiration? I would like to code it in python, therefore if a python block that uses the message passing infrastructure exists, it would be great. Meanwhile I'm going to grep through the code distribution... Thanks!
