Molecular signature module - comparison of gene expression value. The Figure presents a comparison of gene expression of a vaccinated group of individuals against the control group. A spot represents a gene. Position of a spot is determined by the expression of a given gene. Vertical position of a spot represents expression of the gene of the vaccinated group while horizontal position of a spot represents expression of the gene of the control group. Filtering mechanism could be applied in order to remove from the analysis genes, which expression’s ratio is lower than some threshold (the empty space on the diagonal of the chart).
