In section 5.6.1 of the gromacs 3.3 manual (which deals with the
description of the format of the .top topology file), table 5.3 implies
that the lines following the dihedraltypes directive must have the form
of two atom types, followed by the function type, followed by the
In fact, as made clear in kernel/toppush.c, lines with four atom types,
function type and parameters are also read.
What is the behaviour of gromacs when dealing with such four atom-type
dihedrals? Does it implement them correctly by matching all four atoms,
or does it drop the extra information and only match dihedraltypes on
the central two atoms? Can the manual please be updated to reflect
whichever of these is true?
