Highest e value in blast possible
Web4 de mar. de 2024 · Step 1: The first step is to create a lookup table or list of words from the query sequence. This step is also called seeding. First, BLAST takes the query sequence and breaks it into short segments called words. For protein sequences, each word is usually three amino acids long, and for DNA sequences, each word is usually eleven nucleotides … WebSet the E-value cut-off ("Expect threshold") to 50; Remember to adjust the BLAST settings. ...
