**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
