Dialog Box - called from: Rotation Menu
This will counteract all rotations made by the dialogs in the Rotation menu as well as any made on-screen with dialogs in the Display menu, and take you back to one of two settings. The original orientation means the orientation before any rotations, including the alignment of a slice, and the rotations of the Initial Orientation dialog in the Input2 menu, have been made. The initial orientation is that attained after the rotations just listed have been made, if any of them were actually used. See also Coordinate Systems.
Summary of orientation operations. ATOMS first sets the c structure axis parallel to the z viewer axis, and the a * structure axis (perpendicular to b and c ) parallel to x. This is the original orientation. Next, if the Slice boundary option is in effect, the slice is oriented with the slice plane parallel to yz, and the orientation vector parallel to z. Then the initial Cartesian rotations, if any, are applied. Finally, the clinographic rotations, if selected, are applied. This is the initial orientation.
