The scoring space is a heat map displaying the best scores for all the partial alignments of two sequences. The color of each n1 n2 coordinate in the scoring space represents the best score for the pairing of subsequences Seq1 1 n1 and Seq2 1 n2 where n1 is a position in Seq1 and n2 is a position in Seq2.The best score for a pairing of specific subsequences is determined by scoring all
