**What it does**

This tool converts data from Solexa format to FASTA format (scroll down for format description).

--------

**Example**

The following data in Solexa-FASTQ format::

    @CSHL_4_FC042GAMMII_2_1_517_596
    GGTCAATGATGAGTTGGCACTGTAGGCACCATCAAT
    +CSHL_4_FC042GAMMII_2_1_517_596
    40 40 40 40 40 40 40 40 40 40 38 40 40 40 40 40 14 40 40 40 40 40 36 40 13 14 24 24 9 24 9 40 10 10 15 40

Will be converted to FASTA (with 'rename sequence names' = NO)::

    >CSHL_4_FC042GAMMII_2_1_517_596
    GGTCAATGATGAGTTGGCACTGTAGGCACCATCAAT

Will be converted to FASTA (with 'rename sequence names' = YES)::

    >1
    GGTCAATGATGAGTTGGCACTGTAGGCACCATCAAT
