Example Networks

DiVa online is delivering 3 example networks to facilitate the first steps to usage. The first example network represents transcriptional regulation in Escherichia coli (E. coli) based on experimentally verified interactions [1]. The E. coli network is available at [2].

The second example network denotes transcriptional regulation in the yeast Saccharomyces cerevisiae (S. cerevisiae) based on experimentally verified interactions [3]. The S. cerevisiae network is available at [4].

The third example is the neuronal connectivity network of a simple multicellular organism, i.e. the nematode Caenorhabditis elegans (C. elegans) [5].

Some of the results obtained from DiVa online when using these networke were already published. In particular, this applies to the knockout of vertices [6] and the topological significance of network patterns made up of 3 vertices [7].
