			<P><B>Description:</B>
			</P>
			<P>Using a dihedral style of zero means dihedral forces and energies are
			not computed, but the geometry of dihedral quadruplets is still
			accessible to other commands.
			</P>
			<P>As an example, the <A HREF = "compute_dihedral_local.html">compute
			dihedral/local</A> command can be used to
			compute the theta values for the list of quadruplets of dihedral atoms
			listed in the data file read by the <A HREF = "read_data.html">read_data</A>
			command. If no dihedral style is defined, this command cannot be
			used.
			</P>
			<P>Note that the <A HREF = "dihedral_coeff.html">dihedral_coeff</A> command must be
			used for all dihedral types, though no additional values are
			specified.
