Abstract
Systems biology is an inter-disciplinary research field trying to understand biological complexity as systems. Cooperation between dry research and wet research is necessary to promote systems biology, i.e. technologies of computational science, such as development of detailed models, complicated simulations, and sophisticated data analyses, are playing important roles. Supports from consolidated software platform is essential. In this article we will introduce several software which can be helpful for promoting systems biology, including software that we have been developing.
