Additional File 2.
A Matlab .mat file containing sample GO networks and expression change vectors. This file can be loaded into Matlab using the command load G0_matrix. This will load three matrices (w_All, w_Up and w_Down) and three expression change vectors (expr_data, expr_dataUp and expr_dataDown) into the current workspace. These matrices were constructed using the all three sections of the Gene Ontology, where a link is present between two genes if they share a GO annotation. Only genes which are up-regulated are included in w_Up and only down-regulated in w_Down. The GeneRank algorithm should be used with the corresponding matrix and expression change vector, e.g. the command ranking = geneRank(w_Up, expr_dataUp,d) would be used to calculate the ranking of the up-regulated genes in the experiment.
