Vina | Autodock

You must define a 3D search space (Grid Box) where Vina will look for binding sites.

AutoDock Vina has been widely used in various fields, including: autodock vina

Morris nodded. "We're not looking for the perfect answer. We need the right-enough answer, fast." You must define a 3D search space (Grid

That was the conceptual spark. They decided to break the unwritten rule of docking: that accuracy and speed were eternal enemies. Forli began rewriting the search algorithm from scratch, replacing the sluggish genetic algorithm with a combination of iterative local search and what he called a "broyden–fletcher–goldfarb–shanno" (BFGS) quasi-Newton method. It was a mathematical mouthful, but its effect was profound. Instead of randomly sampling poses like a blindfolded miner, the new method intelligently rolled downhill toward the lowest energy, learning the terrain as it went. We need the right-enough answer, fast

AutoDock Vina offers several key features that make it a powerful tool for molecular docking and virtual screening:

Dr. Stefano Forli, an Italian computational chemist with a passion for elegant code, and Dr. Garrett Morris, a methodical scientist with a background in physics, inherited a legacy tool: AutoDock 4. It was powerful but notoriously slow. A single docking simulation could take minutes, even hours, and screening a library of a hundred thousand drug-like molecules against a protein target could consume weeks of supercomputer time. Forli would stare at the logs, watching the genetic algorithms churn through thousands of conformations, feeling the weight of every unnecessary calculation. "There has to be a faster way," he told Morris one evening, pointing at a graph of the scoring function. "The energy landscape is rugged, but our search path is full of detours."
