Genomic alignment tools concentrate on DNA (or to DNA) alignments while accounting for characteristics present in genomic data. SSEARCH2SEQ finds an optimal local alignment using the Smith-Waterman algorithm. LALIGN finds internal duplications by calculating non-intersecting local alignments of protein or DNA sequences. They are can align protein and nucleotide sequences.ĮMBOSS Water uses the Smith-Waterman algorithm (modified for speed enhancements) to calculate the local alignment of two sequences.ĮMBOSS Matcher identifies local similarities between two sequences using a rigorous algorithm based on the LALIGN application. Local alignment tools find one, or more, alignments describing the most similar region(s) within the sequences to be aligned. GGSEARCH2SEQ finds an optimal global alignment using the Needleman-Wunsch algorithm. Global alignment tools create an end-to-end alignment of the sequences to be aligned.ĮMBOSS Needle creates an optimal global alignment of two sequences using the Needleman-Wunsch algorithm.ĮMBOSS Stretcher uses a modification of the Needleman-Wunsch algorithm that allows larger sequences to be globally aligned. From the output of MSA applications, homology can be inferred and the evolutionary relationship between the sequences studied. Pairwise Sequence Alignment is used to identify regions of similarity that may indicate functional, structural and/or evolutionary relationships between two biological sequences (protein or nucleic acid).īy contrast, Multiple Sequence Alignment (MSA) is the alignment of three or more biological sequences of similar length.
