Using the Supersym Pymol plugin

The SuperSym Pymol plugin by Stuart Ballard allows you to visualize spacegroup symmetry within pymol.

The plugin however depends on the cctbx package to function and compute the symmetry related molecule positions.

To get the plugin working follow these steps:

Install cctbx standalone from the cctbx distribution site. Briefly , download the cctbx standalone build self-executable script . Run the script in any directory. This will build the cctbx library and also create a python startup script with all the modules required for cctbx into the pymol module load path. The script is called cctbx.python and is a simple shell script

me@mymachine:/rawdata12/cctbx_standalone/cctbx_build/bin$ find .* -name "cctbx.python"
../bin/cctbx.python

Edit the pymol startup script to start pymol with the beefed up cctbx python .

#!/bin/sh
PYMOL_PATH=/home/myname/pymol/trunk/pymol
export PYMOL_PATH
#exec /usr/bin/python $PYMOL_PATH/modules/launch_pymol.py "$@"
exec /rawdata12/cctbx_standalone/cctbx_build/bin/cctbx.python $PYMOL_PATH/modules/lau
nch_pymol.py "$@"

Run pymol and have it Install the sypersym plugin as described on the PYMOLWiki.
