Evaluating gene networks with respect to known biology is a common task but often a computationally costly one. Many computational experiments are difficult to apply exhaustively in network analysis due to run-times. To permit high-throughput analysis of gene networks, we have implemented a set of very efficient tools to calculate functional properties in networks based on guilt-by-association methods. EGAD: ( E: xtending ' G: uilt-by- A: ssociation' by D: egree) allows gene networks to be evaluated with respect to hundreds or thousands of gene sets. The methods predict novel members of gene groups, assess how well a gene network groups known sets of genes, and determines the degree to which generic predictions drive performance. By allowing fast evaluations, whether of random sets or real functional ones, EGAD: provides the user with an assessment of performance which can easily be used in controlled evaluations across many parameters. AVAILABILITY AND IMPLEMENTATION: The software package is freely available at and implemented for use in R and Matlab. The package is also freely available under the LGPL license from the Bioconductor web site ( CONTACT: JGillis@cshl.eduSupplementary information: Supplementary data are available at Bioinformatics online.
