|

</P>
|
|
<P>Set the origin of the lattice defined by the <A HREF = "lattice.html">lattice</A>
|
|
command. The lattice is used by the <A HREF = "create_atoms.html">create_atoms</A>
|
|
command to create new atoms and by other commands that use a lattice
|
|
spacing as a distance measure. This command offsets the origin of the
|
|
lattice from the (0,0,0) coordinate of the simulation box by some
|
|
fraction of a lattice spacing in each dimension.
|

</P>
|
|
<P>The specified values are in lattice coordinates from 0.0 to 1.0, so
|
|
that a value of 0.5 means the lattice is displaced 1/2 a cubic cell.
