A Bayesian network is used to model the regulatory structure and Markov-Chain-Monte-Carlo is applied to sample the activity states. } \details{ \tabular{ll}{ Package: \tab birta\cr Type: \tab Package\cr Version: \tab 0.99.1\cr Date: \tab 2012-03-6\cr License: \tab GNU GENERAL PUBLIC LICENSE (GPL) >= 2 \cr LazyLoad: \tab yes\cr } } \author{ Benedikt Zacher, Khalid Abnaof, Stephan Gade, Erfan Younesi, Achim Tresch, Holger Frohlich Maintainer: Benedikt Zacher } \references{ B.
