WebAug 2, 2024 · The algorithm behind BLAST increases speed of the database searches compared to the Smith-Waterman algorithm. Some matches between query sequences and database sequences may be missed by BLAST, and the method does not guarantee identification of the optimal alignment between query and database sequence. WebSep 27, 2001 · Like FASTA, BLAST does not allow gaps in the primary word-matching pass, but it does in the subsequent Smith-Waterman alignment stage.

WebBLAST (20) and FASTA (19) place additional restrictions on the alignments that they report in order to speed up their operation. Because of this Smith Waterman is more sensitive than either BLAST or FASTA Smith-waterman is mathematically rigorous, it is guaranteed to find the best scoring alignment between the pair of sequences being compared. WebSSearch does a rigorous Smith-Waterman search for similarity between a query sequence and a group of sequences of the same type (nucleic acid or protein). This may be the most sensitive method available for similarity searches. Compared to BLAST and FastA, it can be very slow. DESCRIPTION [ Previous Top Next]
