MSL

MSL is a open source C++ software library for molecular modeling produced in the Senes Lab at the University of Wisconsin-Madison, in collaboration with a team or researchers from a number of Universities and companies.

Philosophy

The main goal is to create a set of tools that enable the computational study of macromolecules with relative ease at all levels, from simple operations (for example, load a PDB and measure a distance or edit a dihedral) to complex applications (protein modeling or design).

The MSL library is not a program (although some applications are distributed) but a tool for scientist to code their own methods.

Features

Some of the features supported by the library are:

  • Support for reading and writing PDB and CRD files.

  • The ability of storing and switching between multiple atom coordinates, for conformational changes and rotameric representation of side chain conformational freedom.

  • For protein design, the ability to build and store multiple residue identities (i.e. LEU, ILE, ALA) at a position and switch between them.

  • Support for rotamer libraries.

  • Transformations such as translations, rotations, and alignments.

  • The CHARMM force field and other energy funtions.

  • Support for CHARMM topology and parameter files.

  • Structure building from scratch (using internal coordinates)

  • Search algorithms such as Monte Carlo, Dead End Elimination, and Self Consistent Mean Field Monte Carlo.

  • Local backbone sampling.

  • Crystal lattice generation.

  • A PyMOL Python Interface for calling MSL code from within PyMOL.

  • A R Interface for calling arbitrary R algorithms or plotting routines from within MSL

  • And more...

Documentation

The Documentation – currently still under construction – provides a description of the objects and of some distrubuted programs and utilites. A step by step tutorial is being assembled.
