Table 2 Position Weight Matrix. A count of nucleotides j ∈ {A, T, G, C} at each position k = 1..l in all the sequences of the data set. C k is the kthnucleotide of the consensus pattern which represents the nucleotide with the highest value in that column. Let the consensus pattern be GACT...G and b j be the background.
