What is Rosetta?
Rosetta is a comprehensive computational modeling suite for macromolecules (proteins, nucleic acids, and complexes). Originally developed in David Baker's lab at the University of Washington, it has become a gold standard for protein structure prediction, protein design, docking, and engineering.
- Programming Core
Written in C++ with modular frameworks.
- Interfaces
- Command-line Rosetta (high-performance for batch runs)
- PyRosetta (Python API for flexible scripting)
- RosettaScripts (XML-based customization of workflows)
- Community Driven
Actively maintained by the RosettaCommons consortium, ensuring continuous updates.
Core Capabilities of Rosetta
