Description

This script calculates the true center-of-mass (COM) or the center-of-geometry (COG) for a given selection and returns the x, y, z values in the form of a Pseudoatom (rather than a CGO sphere). The benefit of using a Pseudoatom is that it can be selected and used in calculations. In addition, this script also iteratively goes through all states of a selection if more than one state exists and appends the corresponding COM/COG values as states into the Pseudoatom. The script itself is quite simple yet robust enough to be applied in different settings. As well, the calculation of the COM/COG is handled independently from the formation of the Pseudoatom and can be called as an independent function where applicable.

Usage

com selection [,state=None [,mass=None [,object=None]]]
