 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
