**What it does**

Converts tab delimited data into FASTA formatted sequences.

-----------
	
**Example**

Suppose this is a sequence file produced by Illumina (Solexa) sequencer::

	5	300	902	419	GACTCATGATTTCTTACCTATTAGTGGTTGAACATC
	5	300	880	431	GTGATATGTATGTTGACGGCCATAAGGCTGCTTCTT
	
Selecting **c3** and **c4** as the **Title column(s)** and **c5** as the **Sequence column** will result in::

	&gt;902_419
	GACTCATGATTTCTTACCTATTAGTGGTTGAACATC
	&gt;880_431
	GTGATATGTATGTTGACGGCCATAAGGCTGCTTCTT
