			dihedral_style zero command
			===========================

			Syntax
			""""""

			.. parsed-literal::

			dihedral_style zero nocoeff

			Examples
			""""""""

			.. parsed-literal::

			dihedral_style zero
			dihedral_style zero nocoeff
			dihedral_coeff *

			Description
			"""""""""""

			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.

			As an example, the :doc:`compute dihedral/local <compute_dihedral_local>` 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 :doc:`read_data <read_data>`
			command. If no dihedral style is defined, this command cannot be
			used.

			The optional nocoeff 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.

			Note that the :doc:`dihedral_coeff <dihedral_coeff>` command must be
			used for all dihedral types, though no additional values are
			specified.

			Restrictions
			""""""""""""
			none

			Related commands: none

			:doc:`dihedral_style none <dihedral_none>`

			Default: none
