Change here the location of the node (0 0 0) of the cell (or list of
cells, previously selected with Cell->Select, when 
Global is pressed).
Parameters for empty entries or 
Local choices remain unchanged.
o1, o2, o3
These entries provide the coordinates of the node in the lower-left 
corner of the cell where the new origin is, calculated with conventional 
or primitive cell vectors. When the lattice is primitive or vectors are 
primitive, this corner node becomes the new origin node (0 0 0) and no more
coordinates are needed.
The cell position, given by the coordinates x,y,z of the origin node,
is not affected by a change in the origin node, so the new origin node
must occupy the position kept by the previous origin node, forcing a
cell translation. The new cell origin can be outside the current cell volume.
o4
When the lattice is centered and vectors are conventional,
a fourth coordinate 
o4 is needed to point the new origin
node (000) to one of the centered nodes. By default, 
o4
is 
000, so no change is introduced. When the cell lattice
is primitive 
P or the vectors defining the origin are primitive,
that is the only possible value for 
o4. For I, C, F, R centered
lattices, 
o4 can also take the values:
I: 111
C: 110
F: 110, 101, 011
R: 211, 122
corresponding to the numerators of the inner node coordinates,
(1/2 1/2 1/2) for 
I lattices, (1/2 1/2 0) for 
C
lattices, (0 1/2 1/2) (1/2 0 1/2) (1/2 1/2 0) for 
F
lattices and (1/3 2/3 2/3) (2/3 1/3 1/3) for 
R lattices.
Vectors
Indicate the type of cell vectors, 
Conventional or 
Primitive,
used to determine the node with 
o1, 
o2, 
o3 coordinates,
as described above. When 
o4 is not 
000, a centered cell is
involved and 
Vectors must be 
Conventional.
Axes
Controls whether cell axes are visible. Axes are positioned at node 
(0 0 0), and can be represented either by conventional or by primitive 
vectors. The three axes use the rgb color scheme: red for the first 
axis, green for the second and blue for the third.
Vectors
Indicate the type of cell vectors to show, 
Conventional 
or 
Primitive. These are totally independent of the vectors 
used to indicate the node (0 0 0).
