**What it does**

This tool converts FASTQ sequencing reads to a Tabular file.

It is conventional to take the first word of the FASTQ "@" title line as the identifier, and any remaining text to be a free form description.
It is therefore often useful to split this text into two columns in Galaxy (identifier and any description) by setting **How many columns to divide title string into?** to **2**.
In some cases the description can be usefully broken up into more columns -- see the examples .

Tab characters, if present in the source FASTQ title, will be converted to spaces.

-----

**Example**

Consider the following two 454 reads in Sanger FASTQ format (using line wrapping for display, but do note not all tools will accept line wrapped FASTQ files)::

 @FSRRS4401BE7HA [length=395] [gc=36.46] [flows=800] [phred_min=0] [phred_max=40] [trimmed_length=95]

By default this is converted into a 3 column tabular file, with the full FASTQ title used as column 1:

=================================================================================================== ============== ==============
FSRRS4401BE7HA [length=395] [gc=36.46] [flows=800] [phred_min=0] [phred_max=40] [trimmed_length=95] tcagTTAA...nnn FFFDDDDD...!!!
FSRRS4401BRRTC [length=145] [gc=38.62] [flows=800] [phred_min=0] [phred_max=38] [trimmed_length=74] tcagCCAG...gnn FFFFFFFF...5!!
=================================================================================================== ============== ==============

If you specified the title should be turned into 2 columns, you'd get 4 columns in total:

============== ==================================================================================== ============== ==============
FSRRS4401BE7HA [length=395] [gc=36.46] [flows=800] [phred_min=0] [phred_max=40] [trimmed_length=95] tcagTTAA...nnn FFFDDDDD...!!!
FSRRS4401BRRTC [length=145] [gc=38.62] [flows=800] [phred_min=0] [phred_max=38] [trimmed_length=74] tcagCCAG...gnn FFFFFFFF...5!!
============== ==================================================================================== ============== ==============

Similarly, for this example treating the title string as 7 columns makes sense:

============== ============ ========== =========== ============= ============== =================== ============== ==============
FSRRS4401BE7HA [length=395] [gc=36.46] [flows=800] [phred_min=0] [phred_max=40] [trimmed_length=95] tcagTTAA...nnn FFFDDDDD...!!!
FSRRS4401BRRTC [length=145] [gc=38.62] [flows=800] [phred_min=0] [phred_max=38] [trimmed_length=74] tcagCCAG...gnn FFFFFFFF...5!!
============== ============ ========== =========== ============= ============== =================== ============== ==============

Note the sequences and quality strings have been truncated for display purposes in the above tables.
