MSL: an open source C++ library for analysis, manipulation, modeling and design of macromolecules.

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 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.
  • Transformations such as translations, rotations, and alignments.
  • The CHARMM force field and other potential energies.
  • 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.

Status

Version 1.0 of MSL was released on July 8, 2012, which is suitable for production.

The libraries are in an advanced are in active development, and a development version is also available (use it at your own risk).

Source

The source code can be downloaded on SourceForge. Go to the Download page. ("To do" list).
