fastq-tools
===========

This package provides a number of small and efficient programs to perform common
tasks with high throughput sequencing data in the FASTQ format. All of the
programs work with typical FASTQ files as well as gzipped FASTQ files.

index
-----

The following programs are provided. See the individual man pages for more
information.

* *fastq-sort* : sort fastq entries by various keys

* *fastq-grep* : match sequences against regular expressions

* *fastq-kmers* : count k-mer occurrences

* *fastq-match* : (smith-waterman) local sequence alignment

* *fastq-qual* : tabulate quality scores

* *fastq-sample* : randomly sample reads, with or without replacement

* *fastq-uniq* : count duplicate reads

* *fastq-qualadj* : adjust quality scores by a fixed offset

install
-------

On most systems, installation is as simple as `./configure && make install`.

If the source was obtained from the git repository, the included `./autogen.sh`
script must be run first to generate the `configure` script.

The only external dependencies are PCRE (http://www.pcre.org/) and zlib
(http://zlib.net/).
