[gmx-users] g_energy help

[ANDRES ADOLFO ORTEGA GUERRERO]

Hi dear Gromacs User , i was wondering if one of you could help me with
something

i use genergygroups to  molecules of my system CNT PROTEIN

so when i use g_energy i can see two types of interaction like Coulomb and
LJ,
What does mean CNT-CNT and CNT-rest interaction? or PROTEIN-PROTEIN,
PROTEIN-rest ??

Thank You
