The MMTSB Tool Set is a collection of perl-based user-level utilities as well as programming libraries for multiscale protein structure modeling. Intended applications include protein structure prediction, loop modeling, structure refinement, and structure evaluation/scoring.

The MMTSB Tool Set interfaces with CHARMM and Amber for all-atom modeling and with MONSSTER for lattice-based low-resolution modeling. It provides conversion routines between high and low resolution models and implements efficient ensemble-based sampling techniques.

The MMTSB Tool Set can be downloaded from this page as a single, easy-to-install source package. It is available free of charge for academic use, but registration is required. Please read the license terms and requirements before downloading.
