sci-chemistry jlec@gentoo.org BALBES is a system for solving protein structures using x-ray crystalographic data. Molecular Replacement(MR) is its core scientific method. BALBES aims to integrate all components, necessary for finding a solution structure by MR, into one system. It consists of a database, scientific programs and a python pipeline. The system is automated so that it needs no user's intervention when running complicated combination of jobs such as model searching, molecular replacement and refinement.
