The main purpose of the program FANTOM (Fast Newton - Raphson Torsion Angle Minimizer) is the calculation of conformations of linear and cyclic polypeptides and proteins with low conformational energies including distance and dihedral angle constraints from nuclear magnetic resonance experiments or for modeling purposes. The user can run energy minimizations and/or Monte Carlo simulations of an empirical energy function. Protein-solvent interaction is included with a fast routine for the calculation of accessible surface areas of individual atoms and their gradients. FANTOM is also suited for the exploration of low energy conformations of cyclic peptides or flexible loops in proteins.
