	Yu need to transformate trh coordinates this way:

		Y=A*X+B

where
	X vector with the three coordinates of model
	Y vector with the three new coordinates
	A 3x3 rotation matrix
	B vector of translation

	You van make a program or programs like X-plor or packages like
CCP4 can do it for you.

	Hope it helps

	Angel

Once's happenstance,twice's coincidence,the third time is enemy action.
  Play, Mr. Bond. You'll need a great deal of luck to get out of this.
