<DIV>Dear GROMACS Users,</DIV>
<DIV> </DIV>
<DIV> Some force fields (AMBER, Tripos/Sybyl) considers 1-4
VdW and electrostatic interactions.</DIV>
<DIV> The GROMACS manual says that the non-bonded
interactionas are based</DIV>
<DIV>on a neighbor list, in which exclusions are alrady removed.</DIV>
<DIV> The bonded interactions are based on a fixed list of
atoms. They include</DIV>
<DIV>4-body, dihedral angle interactions.</DIV>
<DIV> Does combination of the two definitions mean that
GROMACS does not</DIV>
<DIV>consider 1-4 VdW and electrostatics? If it still does, does GROMACS
use</DIV>
<DIV>different scaling factors (if at all) for these interactions as compared
to</DIV>
<DIV>regular, 1-5 or higher ineteractions? (For example, AMBER does it.)</DIV>
<DIV> </DIV>
<DIV>Thanks, Peter Nagy</DIV>
