-    '''Class performs in silico digestion of fastq reads and contains relevant stats.
-        
-        Arguments
-        ---------
-        read - read in fastq format to be digested.
-        cutsite - compiled regex for the site of digestion.
-        flashed - determines if reads have been combined (i.e. using FLASh).
-        minimum_slice_length - determines the minimum number of basepairs for a valid slice.
-        slice_offset - all output slices will be labled by slice_offset + slice number. (useful for unflashed pairs)
-        keep_cutsite - removes the cutsite from the output slice if False
-
-        Attributes
-        ---------
-        recognition_sites - list of identified restriction sites in the read
-        slices_total_counter - number of un-validated slices in the read
-        slices_valid_counter - number of validated slices in the read
-        slices - list of slices in fastq format (string)
-
-        Methods
-        --------
-        get_slices - splits the read based on recognition_sites, validates and returns all valid slices as a list.

+====================
+Running the pipeline
+====================
+
+This section provides details on how to run the pipeline.
+
+Pipeline set-up
+======================
+
+**Step 1**: To run the pipeline you will need to create a :term:`working directory`
+and enter it. For example::
+
+   mkdir cc_pipeline/
+   cd cc_pipeline/
+
+The pipeline will be executed here and all files will be generated
+in this directory.
+
+**Step 2**: Edit a copy of capturec_pipeline.yml:
+
+The YAML file allows the pipeline to be parameterised for different situations.
+Furthermore the pipeline requires a number of additional files in order to run.
+
+A blank copy can be generated by running:
+::
+    ccpipeline get_yaml
+
+This can then be edited using standard text editors e.g.:
+::
+    # To use gedit
+    gedit capturec_pipeline.yml
+
+    # To use nano
+    nano capturec_pipeline.yml
+
+**Note** - currently the yaml file must be named capturec_pipeline.yml for the
+pipeline to recognise it and run correctly.
+
+**Step 3**: Copy or link fastq files into the :term:`working directory`:
+
+The pipeline requires that fastq files are paired and in any of these formats:
+
+    * samplename_R1.fastq.gz
+    * samplename_1.fastq.gz
+    * samplename_R1.fastq
+    * samplename_1.fastq
+
+All fastq files present in the directory will be processed by the pipeline.
+Original fastq files will not be modified and will not be re-run if processing
+has already been completed. If new fastq files are added to a pre-run pipeline,
+only the new files will be processed.
+
+Gziped files are handled appropriately without the need for extraction if .gz is
+present at the end of the file name. Multi-lane fastq files should be
+concatenated prior to running the pipeline otherwise multiple separate analyses will
+be performed.
+
+Copy:
+::
+    cp PATH_TO_FASTQ/example_R1.fastq.gz.
+
+Symlink example:
+**Note** - Be sure to use the absolute path for symlinks
+::
+    ln -s ABSOLUTE_PATH_TO_FASTQ/example_R1.fastq.gz
+
+
+**Step 4** (optional) - Validate run parameters:
+
+Run parameters present in the yaml file can be tested to (hopefully) ensure the
+pipeline will not crash.
+::
+    ccanalyser validate test_parameters
+
+This script checks that appropriate parameters are passed for trimming and aligning.
+
+Running the pipeline
+=====================
+
+When all components are present, the tasks to be run can be:
+
+Shown with:
+::
+    ccpipeline pipeline show
+
+Plotted in inkscape with:
+::
+    ccpipeline pipeline plot
+
+Run with:
+::
+    # If using all default settings and using a cluster
+    ccpipeline pipeline make
+
+    # Increased verbosity
+    ccpipeline pipeline make -v 3
+
+    # If not using a cluster
+    ccpipeline pipeline make --local

+//	1. Enforce API surface and semantic compatibility with 1.9.x branch
+//	2. Improve the module's maintainability by reducing the storage
+//		paths to a single mechanism.
+//	3. Use the same single mechanism to support "private" and "user" data.
+//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
+//	5. Avoid exposing implementation details on user objects (eg. expando properties)
+//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

+<h1>Running the pipeline<a class="headerlink" href="#running-the-pipeline" title="Permalink to this headline">¶</a></h1>
+<p>This section provides details on how to run the pipeline.</p>
+<div class="section" id="pipeline-set-up">
+<h2>Pipeline set-up<a class="headerlink" href="#pipeline-set-up" title="Permalink to this headline">¶</a></h2>
+<p><strong>Step 1</strong>: To run the pipeline you will need to create a <span class="xref std std-term">working directory</span>
+and enter it. For example:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">mkdir</span> <span class="n">cc_pipeline</span><span class="o">/</span>
+<span class="n">cd</span> <span class="n">cc_pipeline</span><span class="o">/</span>
+</pre></div>
+</div>
+<p>The pipeline will be executed here and all files will be generated
+in this directory.</p>
+<p><strong>Step 2</strong>: Edit a copy of capturec_pipeline.yml:</p>
+<p>The YAML file allows the pipeline to be parameterised for different situations.
+Furthermore the pipeline requires a number of additional files in order to run.</p>
+<p>A blank copy can be generated by running:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ccpipeline</span> <span class="n">get_yaml</span>
+</pre></div>
+</div>
+<p>This can then be edited using standard text editors e.g.:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="c1"># To use gedit</span>
+<span class="n">gedit</span> <span class="n">capturec_pipeline</span><span class="o">.</span><span class="n">yml</span>
+
+<span class="c1"># To use nano</span>
+<span class="n">nano</span> <span class="n">capturec_pipeline</span><span class="o">.</span><span class="n">yml</span>
+</pre></div>
+</div>
+<p><strong>Note</strong> - currently the yaml file must be named capturec_pipeline.yml for the
+pipeline to recognise it and run correctly.</p>
+<p><strong>Step 3</strong>: Copy or link fastq files into the <span class="xref std std-term">working directory</span>:</p>
+<p>The pipeline requires that fastq files are paired and in any of these formats:</p>
+<blockquote>
+<div><ul class="simple">
+<li><p>samplename_R1.fastq.gz</p></li>
+<li><p>samplename_1.fastq.gz</p></li>
+<li><p>samplename_R1.fastq</p></li>
+<li><p>samplename_1.fastq</p></li>
+</ul>
+</div></blockquote>
+<p>All fastq files present in the directory will be processed by the pipeline.
+Original fastq files will not be modified and will not be re-run if processing
+has already been completed. If new fastq files are added to a pre-run pipeline,
+only the new files will be processed.</p>
+<p>Gziped files are handled appropriately without the need for extraction if .gz is
+present at the end of the file name. Multi-lane fastq files should be
+concatenated prior to running the pipeline otherwise multiple separate analyses will
+be performed.</p>
+<p>Copy:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">cp</span> <span class="n">PATH_TO_FASTQ</span><span class="o">/</span><span class="n">example_R1</span><span class="o">.</span><span class="n">fastq</span><span class="o">.</span><span class="n">gz</span><span class="o">.</span>
+</pre></div>
+</div>
+<p>Symlink example:
+<strong>Note</strong> - Be sure to use the absolute path for symlinks</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ln</span> <span class="o">-</span><span class="n">s</span> <span class="n">ABSOLUTE_PATH_TO_FASTQ</span><span class="o">/</span><span class="n">example_R1</span><span class="o">.</span><span class="n">fastq</span><span class="o">.</span><span class="n">gz</span>
+</pre></div>
+</div>
+<p><strong>Step 4</strong> (optional) - Validate run parameters:</p>
+<p>Run parameters present in the yaml file can be tested to (hopefully) ensure the
+pipeline will not crash.</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ccanalyser</span> <span class="n">validate</span> <span class="n">test_parameters</span>
+</pre></div>
+</div>
+<p>This script checks that appropriate parameters are passed for trimming and aligning.</p>
+</div>
+<div class="section" id="id1">
+<h2>Running the pipeline<a class="headerlink" href="#id1" title="Permalink to this headline">¶</a></h2>
+<p>When all components are present, the tasks to be run can be:</p>

+====================
+Installing ccanalyser
+====================
+
+Pre-Installation recommendations
+===============================
+
+1. Install conda if it has not been already using the `conda install instructions <https://docs.conda.io/projects/conda/en/latest/user-guide/install/linux.html#install-linux-silent>`_.
+
+2. If ccanalyser is **not** being installed through conda, first generate a new conda
+environment using the yaml file in the `GitHub repo <https://github.com/sims-lab/capture-c/blob/master/capturec_conda_env.yml>`_:
+::
+    conda env create -f ccanalyser_conda_env.yml
+    conda activate capture-c
+
+3. If you intend to use a cluster e.g. SunGrid engine add the path to the DRMAA interface to your .bashrc:
+::
+    # Access to the DRMAA library: https://en.wikipedia.org/wiki/DRMAA
+    echo "export DRMAA_LIBRARY_PATH=/<full-path>/libdrmaa.so" >> ~/.bashrc
+
+    # You can get this value from your configured environment:
+    env | grep DRMAA_LIBRARY_PATH
+
+    # or just look for the library:
+    find / -name "*libdrmaa.so"
+
+
+Installation
+======================
+
+The package can be installed in several ways:
+
+1. Install from conda:
+::
+    conda install ccanalyser
+
+2. Install from pypi:
+::
+    pip install ccanalyser
+
+3. Install from GitHub:
+::
+    git clone https://github.com/sims-lab/capture-c.git
+    cd capture-c
+    pip install .

+====================
+Running the pipeline
+====================
+
+This section provides details on how to run the pipeline.
+
+Pipeline set-up
+======================
+
+**Step 1**: To run the pipeline you will need to create a :term:`working directory`
+and enter it. For example::
+
+   mkdir cc_pipeline/
+   cd cc_pipeline/
+
+The pipeline will be executed here and all files will be generated
+in this directory.
+
+**Step 2**: Edit a copy of capturec_pipeline.yml:
+
+The YAML file allows the pipeline to be parameterised for different situations.
+Furthermore the pipeline requires a number of additional files in order to run.
+
+A blank copy can be generated by running:
+::
+    ccpipeline get_yaml
+
+This can then be edited using standard text editors e.g.:
+::
+    # To use gedit
+    gedit capturec_pipeline.yml
+
+    # To use nano
+    nano capturec_pipeline.yml
+
+**Note** - currently the yaml file must be named capturec_pipeline.yml for the
+pipeline to recognise it and run correctly.
+
+**Step 3**: Copy or link fastq files into the :term:`working directory`:
+
+The pipeline requires that fastq files are paired and in any of these formats:
+
+    * samplename_R1.fastq.gz
+    * samplename_1.fastq.gz
+    * samplename_R1.fastq
+    * samplename_1.fastq
+
+All fastq files present in the directory will be processed by the pipeline.
+Original fastq files will not be modified and will not be re-run if processing
+has already been completed. If new fastq files are added to a pre-run pipeline,
+only the new files will be processed.
+
+Gziped files are handled appropriately without the need for extraction if .gz is
+present at the end of the file name. Multi-lane fastq files should be
+concatenated prior to running the pipeline otherwise multiple separate analyses will
+be performed.
+
+Copy:
+::
+    cp PATH_TO_FASTQ/example_R1.fastq.gz.
+
+Symlink example:
+**Note** - Be sure to use the absolute path for symlinks
+::
+    ln -s ABSOLUTE_PATH_TO_FASTQ/example_R1.fastq.gz
+
+
+**Step 4** (optional) - Validate run parameters:
+
+Run parameters present in the yaml file can be tested to (hopefully) ensure the
+pipeline will not crash.
+::

+This script checks that appropriate parameters are passed for trimming and aligning.
+
+Running the pipeline
+=====================
+
+When all components are present, the tasks to be run can be:
+
+Shown with:
+::
+    ccpipeline pipeline show
+
+Plotted in inkscape with:
+::
+    ccpipeline pipeline plot
+
+Run with:
+::
+    # If using all default settings and using a cluster
+    ccpipeline pipeline make
+
+    # Increased verbosity
+    ccpipeline pipeline make -v 3
+
+    # If not using a cluster
+    ccpipeline pipeline make --local
+
+
+Troubleshooting
+===============
+
+**Interruptions to the pipeline**
+
+If for any reason the pipeline interrupted, simply delete any malformed file or
+directory and re-run the pipeline. The pipeline will then continue with the analysis
+without needing to start from the beginning.
+
+Leftover ctmpXXX.sh files can be safely deleted if the pipeline has stopped running.
+::
+    rm -f *.sh*
+
+To restart the pipeline from the beginning for whatever reason, simply delete all
+processed files and re-run the pipeline:
+::
+    rm -rf fastq_pre-processing/ aligned/ ccanalysis/ run_statistics/ pipeline.log
+    ccpipeline pipeline make -v 3
+
+
+**DRMAA error**
+
+One of the most common errors when running the pipeline is::
+
+    GLOBAL_SESSION = drmaa.Session()
+    NameError: name 'drmaa' is not defined
+
+This error occurrs because you are not connected to the cluster.
+See :ref:`Pre-Installation recommendations`  for how to add DRMAA_LIBRARY_PATH to your bashrc.
+Alternatively, if you do not want to use a cluster (or can't) you can run the
+pipeline in local mode see above.
+
+**KeyError: 'missing parameter accessed'**
+
+This occurs if one of the keys in capturec_pipeline.yml has been altered or deleted.
+Either find the source of the error or get a new version of the yaml file and fill it out.
+
+**ValueError: not enough values to unpack (expected 2, got 1)**
+
+The fastq files are not paired correctly. Please ensure that fastq files are in
+the format:
+
+    | NAME-OF-SAMPLE_(R)1.fastq.gz
+    | NAME-OF-SAMPLE_(R)2.fastq.gz
