Parameters not shown are using default settings. Help

(0..100) -- Percent identity (%)
(0..100) -- Percent query coverage per hsp (%)
≥ 30 bp    < 30 bp (Real number) -- Expectation value (E) threshold for saving hits
≥ 30 bp    < 30 bp Word size for wordfinder algorithm (length of best perfect match)

Optional features

Share blast results if the sequences are very similar. Or this.

This means:
1. Will not run bl2seq between the query sequences.
2. Will not run bl2seq between the query sequence(s) and known probe sequences.

The following parameters are format specifiers for tabular blast results. HSP (High-scoring Segment Pair) with values less than that setted will not be considered.
(70..100) -- Percentage of identical matches (%)
(70..100) -- Query Coverage Per HSP (%)
