Number of hits blast
Web7 jun. 2024 · I'm trying to making a BLAST search with a nucleotide sequence and print the best matching hit but not sure about which option/command should I use. There are options like max_hpsp and best_hit_overhang. I don't have an idea about their differences and I want to print just 1 hit. (best matching one) Should i use max_hpsp 1? WebQUESTION 2: How many significant hits does BLAST find (E-value < 0.005)? ( Tip: you can see the number by selecting all significant hits (clicking All under Sequences producing significant alignments with E-value BETTER than threshold) and then looking at the number of selected hits)
