The course will introduce the basic concepts of biological network analysis and provide practical instruction on commonly used bioinformatics tools to analyse and visualize biological networks. The course will start with a short symposium on biological network analysis covering network analysis and theory, visualization of complex networks and application to real biological problems. The symposium will be followed by theoretical and practical sessions where course participants will gain practical knowledge on how to perform different biological network analyses and how to visualize and interpret the results of such analyses.
