**What it does**

DIAMOND_ is a new alignment tool for aligning short DNA sequencing reads to a protein reference database such as NCBI-NR.
On Illumina reads of length 100-150bp, in fast mode, DIAMOND is about 20,000 times faster than BLASTX, while reporting
about 80-90% of all matches that BLASTX finds, with an e-value of at most 1e-5. In sensitive mode, DIAMOND ist about 2,500
times faster than BLASTX, finding more than 94% of all matches.

The DIAMOND algorithm is designed for the alignment of large datasets. The algorithm is not efficient for a small number of query sequences or only a single one of them, and speed will be low. BLAST is recommended for small datasets.

.. _DIAMOND: http://ab.inf.uni-tuebingen.de/software/diamond/

**Input**

Input data is a large protein or nucleotide sequence file.


**Output**

Diamond gives you a tabular output file with 12 columns:

Column 	Description
1 	    Query Seq-id (ID of your sequence)
2 	    Subject Seq-id (ID of the database hit)
3 	    Percentage of identical matches
4 	    Alignment length
5 	    Number of mismatches
6 	    Number of gap openings
7 	    Start of alignment in query
8 	    End of alignment in query
9 	    Start of alignment in subject (database hit)
10 	    End of alignment in subject (database hit)
11 	    Expectation value (E-value)
12 	    Bit score


Supported values for gap open and gap extend parameters depending on the selected scoring matrix.
