PROFASI (PROtein Folding and Aggregation SImulator) is a C++ program package for Monte Carlo simulations of proteins. It provides a set of tools for running simulations and analyzing the generated data. The model implemented uses an all-atom protein description, torsion angles as the degrees of freedom, and a simplified implicit solvent force field.

PROFASI is freely available under GNU General Public Licence (version 3). The current PROFASI version number is 1.5.
