LoopTK: Protein Loop Kinematic Toolkit

LoopTK ships with a rich feature set. It includes:

• Functions for modeling proteins at the level of atoms, residues, loops, and entire chains
• A variety of inverse kinematics algorithms for protein loop closure
• Full I/O support for files in PDB (Protein Data Bank) format
• 3D Visualization for rendering proteins and their conformation spaces
• Many other miscellaneous algorithms for clustering, energy calculations, grid-based collision detection, protein deformation, and more
