PULCHRA is a program for reconstructing full-atom protein models from simplified representations. PULCHRA can read C-alpha only file and generate an all-atom output in a very short time. The initial C-alpha coordinates can be distorted and PULCHRA will try to optimize their positions. Additionally, side chain centers of mass can be used to improve a quality of the reconstruction.
