The developing mammalian brain is one of the most dynamic of biological systems involving numerous cell types each with its own repertoire of gene expression and behavior. GRiTS is a set of new and innovative bioinformatic tools designed to explore the genetic regulator networks of the developing cerebellum. GRiTS enables the researcher to identify sets of genes based on expression patterns and identify relationships between genes and cellular processes during development. The purpose of our poster today provide an high-level structural overview our first year into a four year project. We currently have a number of previously completed datasets which can be explored with our tools. We will also outline the future direction of our toolset including integration with other tools including SGO and ODE.
