    More detailed documentation is available at: https://vamp.readthedocs.org/

    Installation
    ------------

    VAMP
    ~~~~

    1. Download VAMP from https://bitbucket.org/lance_parsons/vamp/downloads
    2. Unarchive into directory
        a. ``tar xzvf vamp-x.x.tar.gz``.
    3. Install VAMP plus python dependencies: 
        a. ``cd vamp-x.x``
        b. ``python setup.py install``
    4. Build documentation (optional)
        a. ``cd docs``
        b. ``make html``



    Third Party Tools
    ~~~~~~~~~~~~~~~~~

    These tools are used by the pipeline and must be installed prior to use. Instructions are available on the respective websites:

    * `FastX Toolkit <http://hannonlab.cshl.edu/fastx_toolkit/>`_
    * `Bedtools <http://code.google.com/p/bedtools/>`_
    * `FastQC <http://www.bioinformatics.babraham.ac.uk/projects/fastqc/>`_
    * `Bowtie <http://bowtie-bio.sourceforge.net/index.shtml>`_
    * `SSAKE <http://www.bcgsc.ca/platform/bioinfo/software/ssake>`_
    * (Optional) `Mugsy <http://mugsy.sourceforge.net/>`_
        * Other alignment tools may be used to generate the required MAF or aligned fasta files.  One option that works well for nearly complete genomes is `LAGAN <http://lagan.stanford.edu/>`_.


    See `VAMP Installation Documentation <https://vamp.readthedocs.org/en/latest/install.html>_` for some tips on installing to system where you are not the administrator.



    Configuration
    -------------

    1. Copy makefiles/config.mk.template to makefiles/config.mk
    2. Edit config.mk, pointing to the appropriate locations for the installed prerequisites



    Usage
    -----

    Preprocessing
    ~~~~~~~~~~~~~

    1. Run ``setup_preprocessing.py`` to generate analysis makefile
    2. Edit analysis makefile to change options, etc.
    3. Run ``make -f PREFIX_preprocess.mk``
    4. To cleanup intermediate files: ``make -f PREFIX_preprocess.mk clean``


    Assembly
    ~~~~~~~~

    1. ``multi_ssake.py``
    2. Run ``clean_multi_ssake.sh`` to cleanup intermediate fasta files (interactive, do NOT use qsub)
    3. Assemble ``ssake_combined.contigs`` (using Gap4 or other long read assembler)
    4. Align contigs to related reference using `Mugsy <http://mugsy.sourceforge.net/>`_.
    5. ``maf_net.py`` to build scaffolds using a related reference genome as a guide


    Annotation Migration and Summary
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    1. Generate an aligned fasta file from reference and new genome(s) 
        * LAGAN can be used if assembly is reasonably complete and strains are similar
        * For more complex alignments or incomplete assemblies, `Mugsy <http://mugsy.sourceforge.net/>`_ has been shown to be effective. Once MAF is generated with MUGSY, use ``maf_net.py`` to generate aligned fasta
    2. Run ``compare_genomes.py aligned.fasta reference.gff``
    3. Run SNPEff on VCF output (optional)
