PyRosetta Book

The Gray Lab at Johns Hopkins University has just released PyRosetta, a Python-based interactive platform for accessing the objects and algorithms within the Rosetta protein structure prediction suite.

In addition to the code, the Gray Lab has put together a book that leads the reader through basics of protein structure and energetics to applications in folding, refinement, docking and design. The focus is on enabling users to write custom scripts, so it includes material on Rosetta fundamentals and the appendices have a list of PyRosetta commands and a breakdown of the input files. The book was beta-tested by students during a course at JHU. The course is a series of workshops that teach how to measure and manipulate protein conformations, calculate energies in low- and high-resolution representations, fold proteins from sequence, model variable regions of proteins (loops), dock proteins or small molecules, design protein sequences, and build custom protocols for operations tailored to particular biomolecular applications

The book can be purchased through Lulu:

RosettaCon 2009 has ended just a few days ago.

This was a very exciting meeting, gathering almost all Rosetta developers from around the world, and representatives of the major industry licensees of Rosetta. The talks were quite diverse, ranging from new Rosetta protocols under development, applications with regards to numerous biological systems, and up to code architecture and future development of the code.

For scientists specializing in a specific field (such as computational structural biology – just off the top of my head) there are rare occasions in which meetings are dedicated entirely to their topic. This was such a conference! All through the three days of conference and one day of hiking, people had talked, discussed, brain stormed, ate, breathed, thought, swam, hiked, mingled and laughed protein structure. If the coffee break was drawn as a comic figure, with bubble clouds to depict thoughts and conversations, it would be a sea of alpha-helices, weird looking loops, rotamers, ligands and co-factors at interfaces, strange folds and stranger rainbow colored cartoon proteins. A modeler’s utopia.
