Information Modelling – what do we mean?  The concepts, relationships and constraints in a domain - these are ontologies  Use the same information models across multiple data sources  Thus we know how one piece of information relates to another

Multiscale Modelling – how do we do it?  Different types of computational model are suitable for different levels of biological scale  E.g. Biochemical reactions can be represented as networks or ODEs. Cellular behaviour can be modelled with agent based models.  Use models at one level of scale, to pass information to models at another level of scale

Conclusion and Future Work  Gene to phenotype annotation tends to use a surgical or anatomical perspective – but we know very little about mechanism or causes  Post-compositional annotation allows a link between multiscale measurement and multiscale modelling  Future plans include scale-linking between SBML models and agent based models, for simulation of Endocardial Cushion Growth
