Performance of strategies with different information sources on BAliBASE. Boxplots show the sum-of-pairs (SP) score achieved by different strategies for alignments in the BAliBASE benchmark database. Boxplots display first, second and third quartiles as vertical lines; outliers are shown as pluses. The strategies tested differ in the combination of pairwise sequence information that is used to construct the alignment graph. Combinations include: C, longest common subsequence, L, the four top scoring local alignments, G, global alignment, M, GTG motifs.
