Ordered Index Seed Algorithm for Intensive DNA Sequence Comparison
- …This paper presents a seed-based algorithm for intensive DNA sequence comparison. The novelty comes from the way seeds are used to efficiently generate small ungapped alignments – or HSPs (High Scoring Pairs) – in the first stage of the search. W-nt words are first indexed and all the 4 W possible …
