This tool runs **megablast** (for information about megablast, please see the reference below) a high performance nucleotide local aligner developed by Webb Miller and colleagues.

-**Parameters** +**Output format**
-- *Word size* (**-W**) : the minimal length of an exact match -- *Identity percentage cut-off* (**-p**) : the minimal identity for an alignment -- *Expectation value* (**-e**) : the maximal expectation value for an alignment -- *Filter query sequence* (**-F**) : mask low-complexity regions in the query sequence +Output of this tool contains 13 columns delimited by Tabs:
+1. Id of your sequence +2. GI of the database hit +3. Length of the database hit +4. % identity +5. Alignment length +6. # mismatches +7. # gaps +8. Start position in your sequence +9. End position in your sequence +10. Start position in database hit +11. End position in database hit +12. E-value +13. Bit score
