This script will draw the eigenvectors of the inertia tensor of the selected part of the molecule.

Usage

tensor selection, name, model

Examples

To draw the inertia tensor of the first model in PDB file 4B2R do:

fetch 4b2r, async=0
hide lines
show cartoon
run inertia_tensor.py
tensor 4b2r & n. n+ca+c & i. 569-623, tensor_dom11, 1
