**What it does**

This tool converts bowtie output map format file to bed format, with the option to extend the 3 primer end.

- Sequence and quality information is lost after conversion
- The output contains a track name at the first row

-----

**Example**

Converting the following bowtie mapped reads::

  SRR073078.2 HWUSI-EAS465_8_1_1_524 length=36	-	chr2	112499209	AGTGTGACTGCATCTCTTCCTTCGTGGGGCTNCAGT	...
  SRR073078.3 HWUSI-EAS465_8_1_1_1054 length=36	+	chr17	75877120	CCACNCCTCCTTTCAAAACACACTGCCAGGTGCGTC	...

will result in::

  track name=/home/xuebing/Research/galaxy/galaxy-dist/database/files/000/dataset_5.dat itemRgb=On
  chr2	112499109	112499245	SRR073078.2-HWUSI-EAS465_8_1_1_524-length=36	1	-	112499209	112499245	0,255,0
