(What this script is actually computing is the centroid not the center of mass. The center of mass is the mass-weighted average of the coordinates.) |

Overview
Centroid is a small script that returns the value of the geometric center (or centroid) of your selection. It also can translate the object of that selection to the origin.
Syntax
centroid (selection=PyMOLSelection), [center=boolean]
Examples
# get the centroid of the polymer
import centroid
fetch 4ins, async=0
centroid polymer
# move some 'ligand' to the origin
centroid ligand, center=1
