WebJan 13, 2016 · The failure of BLAST to find a match is likely to be rare, though, especially with short word lengths. If you find a decent match, it's highly likely that there is a 3-mer (5-mer, etc.) of identical sequence in the pair. But because it's not a guarantee, the use of k-mer word in the process means that BLAST is a heuristic algorithm.
