Hello all -
I'd like to share with you this script that I recently added (with Troels' help) to the PyMOL Wiki.
Given a PyMOL object containing an antibody Fab fragment complex, light and heavy chain IDs for the Fab, and residue numbers for the boundary between variable and constant domains for each chain, the script will output the elbow angle of the Fab complex
and optionally draw a representation of the vectors used to calculate it.
It's under version control in the Pymol-scripts-repo, and any suggestions and/or fixes are welcome.
Please note that elbow_angle requires transformations.py by Christoph Gohlke and com.py by Jason Vertrees, both of which are also available in the Pymol-scripts-repo.
