A macromolecular docking framework
LightDock is a protein-protein, protein-peptide and protein-DNA docking framework based on the Glowworm Swarm Optimization (GSO) algorithm.
The LightDock framework is highly versatile, with many options that can be further developed and optimized by the users: it can accept any user-defined scoring function, can use local gradient-free minimization, the simulation can be restrained from the beginning to focus on user-assigned interacting regions, it supports residue restraints in both receptor and ligand partners and it has support for the use of pre-calculated conformers for both receptor and ligand.
The first version of the LightDock protocol was published in Oxford Bioinformatics journal. Please cite this reference if you use LightDock in your research:

3.1.1. Installing NumPy, Scipy, Cython and Biopython
pip3 install numpy, scipy, cython, biopython, pyparsing, prody
Make sure all libraries are from the same Python 3.5+ series.
3.2. Install LightDock
The fastest way to install LightDock is to use
pip3 install lightdock
3.3. Alternative installations
Please visit the repository documentation on GitHub for alternative installation.
