How accurate are the models?
Each model (and often each parameter) has its author’s assessment of its accuracy, as well as comments from outside experts. The short answer is that most models are OK to within about a factor of 2 in their domain. The long answer is to test out the model and see what it incorporates and what it leaves out. Many models include comments about sensitivity analysis. • How is model accuracy assessed? As models are always an approximation to the biological system, it is particularly important to have an evaluation of model applicability. This is done through a curation system, whereby modelers and experimentalists are invited to comment on specific pathway models. Curation entries receive an accession number. • How can I add more pathways to the database? As with any web project, this is work in progress. At the current time your best bet is to email the database maintainer, Upinder S .Bhalla bhalla@ncbs.res.in, who will figure out how to format and enter your pathway. Very soon we hope to
