PyMOL Plugins are user-developed modules that extend PyMOL's capabilities via the Tcl/Tk user interface. In order to use them, you'll need an Tcl/Tk-based version of PyMOL (on Macs, this means either using Fink or the X11/Hybrid version: copy and rename MacPyMOL
to PyMOLX11Hybrid).

• PyNMR (Leigh Willard and Stephane Gagne)
  Features loading of multiple pdb files, dihedral restraints checks, NOE restraints checks, and superposition routines.
   
• 
  CAVER (Martin Petrek)
  For identifying and visualizing access routes to protein cavities.
  
   
• GPSSpyMOL (Andrew Binkowski)
  A plugin for visualizing surfaces and voids using the CASTp algorithm. This plugin replaces CASTpyMOL.
  
   
• DivScore (Kaushik Raha)
  A plugin for use with Amber ($$$ for commercial usage) and DivCon ($$$ for all usage) that is designed to perform modeling tasks involving proteins and small molecules.
  
   

PyMOL can install plugins into the correct directory automatically, via the "Install Plugin..." menu item.

PyMOL Plugins need to be installed in the following directory:

   $PYMOL_PATH/modules/pmg_tk/startup
   (or /usr/lib/python2.X/site-packages/pmg_tk/startup for distutils-based installs)

On Windows, this is usually:

   C:\Program Files\DeLano Scientific\PyMOL\modules\pmg_tk\startup

On Macintosh, with MacPyMOL launching in X11/Hybrid mode, you need to right-click and "Show Package Contents" on the PyMOLX11Hybrid bundle and copy the plugin into:

   PYMOLX11Hybrid.app/pymol/modules/pmg_tk/startup

If you're unsure where PyMOL is located, then launch PyMOL, type "cd $PYMOL_PATH", and then "pwd"

Some plugins may require that additional programs or files be installed elsewhere, so please check the instructions available with each individual plugin.
