Figure 4From: Detecting DNA regulatory motifs by incorporating positional trends in information contentUpdate formulae for motif parameters. Updates in M-step depend on I w (regime 1 or 2) and the functional form of f (L1 or L2). For position w after the rth iteration, is the expected number of base j at the wth motif position. For ease of notation, the superscript r and subscript w are dropped. The bases, j, are ordered such that n(1) ≥ n(2) ≥ n(3) ≥ n(4).Back to article page
