Introduction

This script allows you to calculate the elbow angle of an antibody Fab fragment object and optionally draw a graphical representation of the vectors used to calculate the elbow angle.

Examples

# load an antibody Fab from the PDB
fetch 3ghe, async=0

# get a nice orientation
orient

# calculate the elbow angle and draw the vectors
elbow_angle 3ghe, draw=1

The black "dumbbells" pass through the centers of mass of the combined variable and constant domains, respectively. The green and red dumbbell denotes the residues used to split the variable and constant domains, with a green ball for the light chain, and a red ball for the heavy chain.
