What is sequana_pipetools ?
============================

**sequana_pipetools** is a collection of tools that assists with the management of `Sequana <https://sequana.readthedocs.io>`_ pipelines, which includes next-generation sequencing (NGS) pipelines like RNA-seq, variant calling, ChIP-seq, and others.

The aim of this package is to simplify the deployment of `Sequana pipelines <https://sequana.readthedocs.io>`_ by
creatin a pure Python library that includse commonly used tools for different pipelines.

Previously, the Sequana framework incorporated alll bioinformatics, Snakemake rules,
pipelines, and pipeline management tools into a single library (Sequana) as illustrated
in **Fig 1** below.

.. figure:: https://raw.githubusercontent.com/sequana/sequana_pipetools/main/doc/veryold.png
    :scale: 40%

    **Figure 1** Old Sequana framework will all pipelines and Sequana library in the same
    place including pipetools (this library).

Whenever changes were made to the Sequana library, a thorough check of the entire library was necessary, despite
having 80% test coverage. Adding new pipelines also necessitated the addition of new dependencies, and the process was becoming increasingly complex. To mitigate this issue, we initially made all pipelines independent, as illustrated in **Fig. 2**. This way, pipeline changes could be made without updating Sequana and vice versa, which was a significant improvment.

.. figure:: https://raw.githubusercontent.com/sequana/sequana_pipetools/main/doc/old.png
    :scale: 40%

    **Figure 2** v0.8 of Sequana moved the Snakemake pipelines in indepdendent
    repositories. A `cookie cutter <https://github.com/sequana/sequana_pipeline_template>`_ 
    ease the creation of scuh pipelines


However, certain tools, such as those used for user interface and input data sanity checks, were required by all pipelines, as depicted by the pipetools box in the figure. As new pipelines were being added every month, we aimed to make the pipelines and Sequana more modular. Consequently, we created a pure Python library known as **sequana_pipetools**, as shown in **Fig. 3**, to make the pipelines even more autonomous.

.. figure:: https://raw.githubusercontent.com/sequana/sequana_pipetools/main/doc/new.png
    :scale: 40%

    **Figure 3** New Sequana framework. The library contains the core and
    bioinformatics tools and is now distinct from  the pipelines. Additionally, the
    sequana_pipetools library supplies common tools to assist in the creaton and management of all pipelines, 
    such as shared parser for options.

Finally, we dropped the rules/ available in Sequana to build an independent package with a set of Snakemake
wrappers. These wrappers are available on https://github.com/sequana/sequana-wrappers and have also the advantage of being tested through continuous integration.

    **Figure 3** New Sequana framework 2021. The library itself with the core, the
    bioinformatics tools is now fully independent of the pipelines. 


Installation
============

from pypi website::

    pip install sequana_pipetools

No dependencies for this package except Python itself. In practice, this package
has no interest if not used with a Sequana pipeline. So, when using it,
you will need to install the relevant Sequana pipelines that you wish to use. For example::

    pip install sequana_rnaseq
    pip install sequana_fastqc
    ...


This package is for `Sequana <https://sequana.readthedocs.io>`_ developers.
To get more help, go to the doc directory and build the local sphinx directory using::

    make html
    browse build/html/index.html

Quick tour
==========

There are currently two standalone tools. The first one is for Linux users under
bash to obtain completion of a sequana pipeline command line arguments::

    sequana_completion --name fastqc

The second is used to introspect slurm files to get a summary of the SLURM log
files::

    sequana_slurm_status --directory .

Will print a short summary report with common errors (if any).


The library is intended to help Sequana developers to design their pipelines.
See the `Sequana organization repository for examples <https://github.com/sequana>`_.

In addition to those standalones, sequana_pipetools goal is to provide utilities to help Sequana developers. 
We currently provide a set of Options classes that should be used to
design the API of your pipelines. For example, the
sequana_pipetools.options.SlurmOptions can be used as follows inside a standard
Python module (the last two lines is where the magic happens)::

    import argparse
    from sequana_pipetools.options import *
    from sequana_pipetools.misc import Colors
    from sequana_pipetools.info import sequana_epilog, sequana_prolog

    col = Colors()
    NAME = "fastqc"

    class Options(argparse.ArgumentParser):
        def __init__(self, prog=NAME, epilog=None):
            usage = col.purple(sequana_prolog.format(**{"name": NAME}))
            super(Options, self).__init__(usage=usage, prog=prog, description="",
                epilog=epilog,
                formatter_class=argparse.ArgumentDefaultsHelpFormatter
            )
            # add a new group of options to the parser
            so = SlurmOptions()
            so.add_options(self)


Developers should look at e.g. module sequana_pipetools.options
for the API reference and one of the official sequana pipeline (e.g.,
https://github.com/sequana/sequana_variant_calling) to get help from examples.

The Options classes provided can be used and combined to design pipelines. 


How to create skeleton of a Sequana pipeline with cookiecutter
=================================================================

In version 0.11 and below, there was a standalone called **sequana_start_pipeline** that would help you to automatically create the structure of a Sequana pipeline. This stadanlone was dropped in version 0.11.1

Since it is based on cookiecutter, it is quite easy to do it yourself as follows::

    pip install cookiecuter
    cookiecutter https://github.com/sequana/sequana_pipeline_template -o . --overwrite-if-exists

and then follow the instructions. You will be asked some questions such as the name of your pipeline (eg. variant), a description, keywords and the *project_slug* (just press enter).


Setting up and Running Sequana pipelines
=========================================


When you execute a sequana pipeline, e.g.::

    sequana_fastqc --input-directory data

a working directory is created (with the name of the pipeline; here fastqc). Moreover, the working directory
contains a shell script that will hide the snakemake command. This snakemake command with make use
of the sequana wrappers and will use the official sequana github repository by default
(https://github.com/sequana/sequana-wrappers). This may be overwritten. For instance, you may use a local clone. To do
so, you will need to create an environment variable::

    export SEQUANA_WRAPPERS="git+file:///home/user/github/sequana-wrappers

If you decide to use singularity/apptainer, one common error on a cluster is that non-standard paths are not found. You can bind them using the -B option but a more general set up is to create thos environment variable::

    export SINGULARITY_BINDPATH="  /path_to_bind"

for Singularity setup, or ::

    export APPTAINER_BINDPATH=" /path_to_bind"

for Apptainer setup.


What is Sequana ?
=================

**Sequana** is a versatile tool that provides 

#. A Python library dedicated to NGS analysis (e.g., tools to visualise standard NGS formats).
#. A set of Pipelines dedicated to NGS in the form of Snakefiles
   (Makefile-like with Python syntax based on snakemake framework) with more
   than 80 re-usable rules.
#. Standalone applications.

See the `sequana home page <https://sequana.readthedocs.io>`_ for details.
