Scaffold Hunter - A tool for the visual analysis and exploration of chemical space

The challenging task in Cheminformatics is to support the drug discovery process by adequate computational methods including largely automated data mining algorithms as well as visual analysis tools. Our research includes algorithms to compare graphs, which are a prerequisite to apply data mining algorithms to structured objects like chemical compounds. Moreover, we develop methods for searching graph databases as well as visual analysis approaches for chemical space.

We develop Scaffold Hunter, a tool for the analysis and exploration of chemical space aiming at an intuitive access to large and complex data sets. The tool offers a variety of views, e.g. graph, dendrogram, and plot view, as well as analysis methods, e.g., for clustering and classification.
