[ESPResSo] Interactions beads same molecule

[Salvador Herrera Velarde]

Dear All,

I would like to know if somebody have an idea how to set the forces in ESPResSO (mbtools) between the same kind of beads in different molecules (lipids) alike to those belonging to the same molecule. 

I am no thinking in a  mixture of lipids. I have  the same kind of lipid, but I need to specify different interactions between intrachain beads and interchain beads. 

Some ideas?

Thanks a lot in advance,

Salvador Herrera
