Change here position and orientation for a single cell or a list of cells.
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.
Translation
The origin of a cell object, defined by its (0 0 0) node,
can be changed using the 
X, 
Y, 
Z entries.
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.
Rotation
The orientation of a cell object, defined by the Euler angles theta,
phi, psi, can be changed using the 
E1, 
E2, 
E3 entries.
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.
To define exactly the cell rotation, relatively to other cell 
or relatively to the current layer, press 
Align.
