This code has been put under version control in the project Pymol-script-repo |

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
```
