<h2>Description</h2>
<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 class="reference internal" href="compute_dihedral_local.html"><span class="doc">compute dihedral/local</span></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 class="reference internal" href="read_data.html"><span class="doc">read_data</span></a>
command. If no dihedral style is defined, this command cannot be
used.</p>
<p>The optional <em>nocoeff</em> flag allows to read data files with a DihedralCoeff
section for any dihedral style. Similarly, any dihedral_coeff commands
will only be checked for the dihedral type number and the rest ignored.</p>
<p>Note that the <a class="reference internal" href="dihedral_coeff.html"><span class="doc">dihedral_coeff</span></a> command must be
used for all dihedral types, though no additional values are
specified.</p>
