Overview
Draws a bounding box around a given selection.
Example of a bounding box
Two bounding boxes, one with 0 padding, the other with 10 Ang padding.
Example
run ~/drawBoundingBox.py
fetch 1jsd
drawBoundingBox 1jsd, r=0.33, g=0.80
# example from above w/padding, draw it light blue
drawBoundingBox padding=10, r=0.5, g=0.8, b=1.0
Installation
Copy the source code to your computer, and execute it by issuing the command "run /path/to/drawBoundingBox.py" in PyMOL.

def drawBoundingBox(selection="(all)", padding=0.0, linewidth=2.0, r=1.0, g=1.0, b=1.0):

DESCRIPTION
Given selection, draw the bounding box around it.
USAGE:
drawBoundingBox [selection, [padding, [linewidth, [r, [g, b]]]]]
PARAMETERS:
selection, the selection to enboxen. :-)
defaults to (all)
padding, defaults to 0
linewidth, width of box lines
defaults to 2.0
r, red color component, valid range is [0.0, 1.0]
defaults to 1.0
g, green color component, valid range is [0.0, 1.0]
defaults to 1.0
b, blue color component, valid range is [0.0, 1.0]
defaults to 1.0
RETURNS
string, the name of the CGO box
NOTES
* This function creates a randomly named CGO box that minimally spans the protein. The
user can specify the width of the lines, the padding and also the color.
