Partner project of the German Network for Bioinformatics Infrastructure (de.NBI)

About de.NBI ModSim


Resources, Services and Developments for Systems Biology Modeling.


de.NBI-ModSim is a partner project of de.NBI-SysBio node and has three major goals:

  1. Adding new resources to de.NBI: in particular, COPASI and CellNetAnalyzer, two complementary and frequently used software packages for modeling biological networks and systems will be promoted by de.NBI-ModSim.
  2. Providing services: extended user support and organization of workshops and training courses on mathematical modeling of biological systems including hands-on exercises with the software tools
  3. de.NBI-relevant developments: for example, integration of COPASI and CellNetAnalyzer with existing resources of de.NBI and make these tools compliant with model standardization and annotation schemes propagated by the de.NBI-SysBio node.
