The PyMol Wiki actively seeks new users and contributors! However, due to massive amount of spamming, we've changed the registration process, until further notice. '''If you would like access,''' you will need to be verified by a system administrator/sysop. To do so, email Jason dot Vertrees at gmail dot com (and tell me why you use PyMol). Also, be sure to include your '''desired user name''', '''real name''', '''temporary password''', and '''email address'''.  Once we figure out a way to automatically prevent spamming, we'll return to the normal method of registration.

Centerofmass

The centerofmass command calculates the center of mass for an atom selection. It considers atom mass and occupancy.

New in PyMOL 1.7.2. See the center_of_mass script for older PyMOL versions.

Usage

centerofmass [ selection [, state ]]

Arguments

  • selection = str: atom selection {default: all}
  • state = int: object state, -1 for current state, 0 for all states {default: -1}

Example

PyMOL> fetch 1ubq, async=0
PyMOL> centerofmass
 Center of Mass: [  30.004,  28.522,  14.701]

Python API

cmd.centerofmass() returns a list of 3 floats.
