"WebSep 30, 2014 · BLAST uses 'chunks' of a given length as an initial matches between query sequence and putative match in database. There is a trade off (sensitivity vs speed): shorter the word size, more sensitive the search. longer word sizes, faster the search. Typical word sizes: blastp: 3 (default), 2. blastn: 28 (default), up to to 64. " - Blastx algorithm

WebJun 16, 2014 · BLAST is a fast, heuristic approximation to the Smith–Waterman algorithm. An analytic theory describes the optimal scores of ungapped local alignments. The statistical parameters for BLAST's gapped local alignments are precomputed by random simulation. Very efficient algorithms exist for finding perfect or near-perfect word matches.

WebBLASTx is one of the three translated BLAST algorithms – namely, BLASTx, tBLASTn and tBLASTx. In BLASTx, a nucleotide sequence is used as a query, which is first translated in all six reading frames, and then each of the translated amino acid sequences is compared to the protein sequences in protein databases. Thus, the comparison occurs at ... WebMar 4, 2024 · BLAST performs sequence alignment through the following steps.
