About
=====

`MAVIS <http://mavis.bcgsc.ca>`__ is python command-line tool for the post-processing of structural variant calls.
The general `MAVIS <http://mavis.bcgsc.ca>`__ pipeline consists of six main stages


* convert
* `cluster <http://mavis.bcgsc.ca/docs/latest/mavis.cluster.html#mavis-cluster>`_
* `validate <http://mavis.bcgsc.ca/docs/latest/mavis.validate.html#mavis-validate>`_
* `annotate <http://mavis.bcgsc.ca/docs/latest/mavis.annotate.html#mavis-annotate>`_
* `pairing <http://mavis.bcgsc.ca/docs/latest/mavis.pairing.html#mavis-pairing>`_
* `summary <http://mavis.bcgsc.ca/docs/latest/mavis.summary.html#mavis-summary>`_

Getting Help
------------

All steps in the MAVIS pipeline are called following the main mavis entry point. The usage menu can be viewed
by running without any arguments, or by giving the -h/--help option

.. code-block::

mavis -h


Help sub-menus can be found by giving the pipeline step followed by no arguments or the -h options

.. code-block::

mavis cluster -h

Install Instructions
--------------------

There are 3 major steps to setting up and installing `MAVIS <http://mavis.bcgsc.ca>`_.

1. Install Aligner
^^^^^^^^^^^^^^^^^^

In addition to the python package dependencies, `MAVIS <http://mavis.bcgsc.ca>`__ also requires an aligner to be installed.
Currently the only aligners supported are `blat <http://mavis.bcgsc.ca/docs/latest/glossary.html#term-blat>`__ and `bwa mem <http://mavis.bcgsc.ca/docs/latest/glossary.html#term-bwa>`_.
For MAVIS to run successfully the aligner must be installed and accessible on the path.
If you have a non-standard install you may find it useful to edit the PATH environment variable. For example

.. code-block:: bash

export PATH=/path/to/directory/containing/blat/binary:$PATH

`blat <http://mavis.bcgsc.ca/docs/latest/glossary.html#term-blat>`__ is the default aligner. To configure MAVIS to use `bwa mem <http://mavis.bcgsc.ca/docs/latest/glossary.html#term-bwa>`__ as a default instead, use the
`MAVIS environment variables <http://mavis.bcgsc.ca/configuration.html#environment-variables>`_. Make sure to specify BOTH of the variables below to change the default aligner.

.. code-block:: bash

export MAVIS_ALIGNER='bwa mem'
export MAVIS_ALIGNER_REFERENCE=/path/to/mem/fasta/ref/file

After this has been installed MAVIS itself can be installed through `pip <https://pypi.org/project/mavis/>`_

2. Install MAVIS
^^^^^^^^^^^^^^^^

Install using pip
~~~~~~~~~~~~~~~~~

The easiest way to install `MAVIS <http://mavis.bcgsc.ca>`__ is through the python package manager, pip. If you do not have python3 installed it can be found `here <https://www.python.org/downloads>`_

Ensuring you have a recent version of pip and setuptools will improve the install experience. Older versions of pip and setuptools may have issues with obtaining some of the mavis python dependencies

.. code-block:: bash

pip install --upgrade pip setuptools

or (for Anaconda users)

.. code-block:: bash

conda update pip setuptools

If this is not a clean/new python install it may be useful to set up mavis in a `virtual python environment <https://docs.python.org/3/tutorial/venv.html>`_

Then install mavis itself

.. code-block:: bash

pip install mavis

This will install mavis and its python dependencies.

Install using Buildout
~~~~~~~~~~~~~~~~~~~~~~

Alternatively you can use the `bootstrap/buildout <http://www.buildout.org/en/latest/>`__ to install mavis into bin/mavis

.. code-block:: bash

git clone https://github.com/bcgsc/mavis.git
cd mavis
pip install zc.buildout
python bootstrap.py
bin/buildout

This will install mavis and its python dependencies into eggs inside the cloned mavis directory which can be used by simply running bin/mavis

3. Build or Download Reference Files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

After `MAVIS <http://mavis.bcgsc.ca>`__ is installed the `reference files <http://mavis.bcgsc.ca/docs/latest/mavis_input.html#reference-input-files>`__ must be generated (or downloaded) before it can be run. A simple bash script to download the hg19 reference files and generate a MAVIS environment file is provided under mavis/tools for convenience.

.. code-block:: bash

cd /path/to/where/you/want/to/put/the/files
wget https://raw.githubusercontent.com/bcgsc/mavis/master/tools/get_hg19_reference_files.sh
bash get_hg19_reference_files.sh
source reference_inputs/hg19_env.sh

Once the above 3 steps are complete `MAVIS <http://mavis.bcgsc.ca>`__ is ready to be run.
See the MAVIS `tutorial <http://mavis.bcgsc.ca/docs/latest/pipeline.html#mavis-mini-tutorial>`__ to learn about running MAVIS.

.. code-block::

pip install .[docs]
sphinx-build docs/source/ html
