I'm a new user of MacPyMOL. I would like to modify the coordinates of
my PDB file such that the origin (0,0,0) is centered at the mid-point
of a molecular bond. I've found that I can make (and save) changes
in the Z and Y coordinates (in 3 button editing mode moving the
structure up/down (Z), left/right(Y)), but I cannot really reliably
shift the X coordinate reliably using the mouse.
So I have 3 questions:
(1) Are there commands that I can type such that I can shift the
coordinate for the entire PDB file without using the mouse?
(2) If the mouse is the only way I can shift coordinates, then how do
I use the mouse so that I can change the X-coordinate?
(3) What does the origin command do?
