It seems like smth very complicated :)
I just need to put two different proteins in the system - one in the
membrane (A) and one in the water (B) and simulate it independently 10
times to collect statistics about associations of A and B during those
runs. The problems that I don't know how to put 2 different unbound
proteins in the MARTINI system.
