[gmx-users] why are the values of the LJ interaction energy negative and the values of the Coulomb interaction energy positive between two group.

Hi gmx-users,
   I have calculated the interaction energy between two group. But I find that the values of the LJ interaction energy are negative and the values of the Coulomb interaction energy are positive between two group. So I think the LJ interaction is attractive and the Coulomb interaction is repulsive. Is it correct for my consideration of the interaction ?
