Matrix_ID(1) and Matrix_ID(2) are the TRANSFAC^® identifiers of the selected single matrix (or the first matrix in a pair and the second matrix in the pair, respectively). The other headings of the table correspond to the parameters of the composite module score (see equation 2 in Materials and methods). The first six lines of the table represent the single matrices selected by the algorithm to represent the global context; the other lines represent the pairs of matrices selected by the CMA program. The corresponding values of the parameters (in the Cut-off, κ and φ columns) are optimized by the CMA algorithm. *Matrices corresponding to TFs whose binding site combinatorial co-occupancy was found in Odom et al. [45] for promoters of liver-expressed genes. Bold text indicates TFs identified by the CMA.
