Visualization

Visual inspection is often a first step in identifying key features of data. The high dimensionality of biological data sets prohibits an intuitive understanding and requires advanced visualization techniques. Our group develops visualization tools to support researchers in inspecting different types of biological data, e.g. for automatic tracking of cells in live cell imaging, displaying locations of SNPs on a caryogram, linking human cytomegalovirus drug resistance mutations to phenotypes, or visualizing the stability of selected gene subsets. Our heavily used VennMaster software provides algorithms to display area-proportional Venn diagrams of set intersections.
