Change here position and orientation for a single cell or a list of cells.
### Translation

The origin of a cell object, defined by its (0 0 0) node,
can be changed using the **X**, **Y**, **Z** entries.
### Rotation

The orientation of a cell object, defined by the Euler angles theta,
phi, psi, can be changed using the **E1**, **E2**, **E3** entries.

To modify an cell, click over its graphic image, or write its identification
(name and number) on the **Cell** entry. To modify a list of cells, press
the button **List** (after creating the list of cells with **Cell->Select**).
Parameters for empty entries or **Local** choices remain unchanged.

To change an cell name write the new name in the **Cell** entry,
followed by the cell number (GAMGI needs the number to identify the cell).
To change the name for a list of cells, press **List** first
and then write the new common name in the **Name** entry.

By default, in **Conventional**, **Primitive** and
**Parallelepiped** volumes, this node is at a corner
of the cell volume, in a **Sphere** volume it is at the
center, and in a **Wigner** volume it is at the center of
the first Wigner-Seitz cell.

To define exactly the cell translation, relatively to other cell or relatively to the current layer, press Align.

Euler angles in GAMGI are defined as follows: first, the (x, y, z) referential is rotated theta degrees (between 0 and 180) around the y axis, then the referential is rotated phi degrees (between 0 and 360) around the initial z axis, and finally it is rotated psi degrees (between 0 and 360) around the new z axis, always in the direct, counter-clockwise, direction. If the first Euler angle (theta) is zero, the old and new z axis coincide, thus (0, 0, 10) and (0, 5, 5) represent the same rotation.

By default, the first conventional vector is aligned with the x axis (even if conventional vectors are not actually represented), the second vector is in the xy plane and the third vector has a positive z coordinate (pointing to the user), corresponding to Euler angles (0, 0, 0).

The cell orientation is independent of the volume representation. This way, conventional, primitive and Wigner-Seitz cells can be easily compared, as they have the same orientation.
