WebI was teaching an introduction to bioinformatics when the students and I noticed strange Blast behavior that we couldn't explain. With the default evalue parameter, our best hit shows an evalue of 3e-06, while that hit … WebFor example, an E -value of 1e-25 (=10 −25) will indicate a clear homology. It should be borne in mind that the E-value is influenced by the query length. A moderately good alignment involving two very long sequences will produce a higher E-value than an extremely good alignment involving two smaller sequences.
How is e-value calculated in BLAST 2 sequences (BLAST+)?
