	<P><B>Description:</B>
	</P>
	<P>Specify the orientation of a cubic lattice along simulation box
	directions <I>x</I> or <I>y</I> or <I>z</I>. These 3 basis vectors are used when the
	<A HREF = "create_atoms.html">create_atoms</A> command generates a lattice of atoms.
	</P>
	<P>The 3 basis vectors B1, B2, B3 must be mutually orthogonal and form a
	right-handed system such that B1 cross B2 is in the direction of B3.
	</P>
	<P>The basis vectors should be specified in an irreducible form (smallest
	possible integers), though LAMMPS does not check for this.
