    • DIALIGN is a novel program for multiple alignment developed by Burkhard Morgenstern et al.and constructs pairwise and multiple alignments by comparing whole segments of the sequences. This approach is very efficient where sequences are not globally related but share only local similarities, as is the case with genomic DNA and with many protein families.
    • MGA allows a direct comparison of the genomic DNA sequences of sufficiently similar organisms by the use of anchored segments.An alignment of 74% of the complete genomes of three of strains of E.coli (lengths: 5,528,445; 5,498,450; 4,639,221 bp.) is produced in 30 minutes. Must been run locally
    • VMatch software tool for efficiently solving large scale sequence matching tasks. It uses string comparisons and masking to make multiple alignments to reveal unique sequences across many genomes and is very fast. Unfortunately Vmatch must also be run locally.
