Dear all
I would like to visually compare (using some molecular graphics
software) the crystal packing of two different crystal forms of the same
protein.
In order to identify the similarities/differences between the crystal
packings, I need to change the default unit cell origin and orientation
of one of the crystal forms.
* Is there a way, in CCP4MG or other molecular graphics software, to
apply a given rotation/translation matrix to a "crystal object" (not to
a single molecular object), so that further expansions of the object by
crystal symmetry will be consistent with the new origin/orientation ?
* If yes: can the transformation be defined by a least-squares
superposition between molecules from the two crystal objects ?
Best regards
