Hi, The first line "eth1" tells it all. In that molecule all non-bonded interactions between first bonded neighbors will be excluded. Thus the 1-3, 1-4 (and so on) non-bonded interactions will be included. You may add additional exclusions in the [ exclusion ] section of your topology.

Dear all, I am unclear about the bond exclusion properties within gromacs. Using a martini model system, what is the default behavior of setting [moleculetype] ;name exclusions eth 1 exclusions to 1? How do I find out what kind of interaction it is excluding? I am interested in finding
