The creation of accurate quantitative Systems Biology Markup Language (SBML) models is a time-intensive manual process. Modellers need to know and understand both the systems they are modelling and the intricacies of SBML. However, the amount of relevant data for even a relatively small and well-scoped model is overwhelming. Saint, an automated SBML annotation integration environment (for an example installation, see http://www.cisban.ac.uk/saint), aims to aid the modeller and reduce development time by providing extra information about any given SBML model in an easy-to-use interface. Saint accepts SBML-formatted files and integrates information from multiple databases automatically. Any new information that the user agrees with is then automatically added to the SBML model.
