High scoring segment pairs
WebJan 3, 2024 · This can be via a gapped or un-gapped alignment extension in either direction to get sequence pairs with high scores or HSPs (High Scoring Segment Pairs). This process is called seeding. Those HSPs that are above a cutoff score (S) are reported in the BLAST output and the extension process is terminated when the HSPs are below cut-off. This is ... WebA modification of the Smith-Waterman or Sellers algorithms will find all segment pairs whose scores can not be improved by extension or trimming. These are called high …

WebMar 22, 2024 · I find BLAST often detect multiple High-scoring Segment Pairs (HSPs) from a comparison of a pair of sequences. Sometimes, parts of these multiple HSPs may overlap. For example, BLAST returned two HSPs, the first at 310~711 of the query sequence and the second at 695~824 (overlapping with the first), with scores 181 and 116, respectively. WebJul 1, 1993 · The statistical distribution of high-scoring segments has been described elsewhere. However, molecular sequences will frequently yield several high-scoring segments for which some combined ...
Web(a) The maximal segment pair measure Sequence similarity measures generally can be classified as either global or local. Global similarity algorithms optimize the overall alignment of two sequences, which may include large stretches of low similarity (Needleman & Wunsch, 1970).
