Blastp identity threshold
WebFor the first screening, all BLASTP results were filtered by e-value (≤1.0e − 8) and hit length coverage (≥50% of a query sequence). Then, to tentatively assign the taxonomic origins of the genes, we adopted a 90% BLASTP identity threshold. The genes with best-hit pairs under the threshold were assigned as ‘No hits’. WebAug 10, 2024 · What was the threshold on the E-value for this blastp search? 4. With this threshold, how many hits would we expeect if we use a random sequence as query? 5. How many alignments would you consider significant in this result? 6. How many of these would you qualify of homologs? 7.
