+# Welcome to Biopet
+
+
+## Introduction
+
+Biopet (Bio Pipeline Execution Toolkit) is the main pipeline development framework of the LUMC Sequencing Analysis Support Core team. It contains our main pipelines and some of the command line tools we develop in-house. It is meant to be used in the main [SHARK](https://humgenprojects.lumc.nl/trac/shark) computing cluster. While usage outside of SHARK is technically possible, some adjustments may need to be made in order to do so.
+
+
+## Quick Start
+
+### Running Biopet in the SHARK cluster
+
+Biopet is available as a JAR package in SHARK. The easiest way to start using it is to activate the `biopet` environment module, which sets useful aliases and environment variables:
+
+~~~
+$ module load biopet/v0.3.0
+~~~
+
+With each Biopet release, an accompanying environment module is also released. The latest release is version 0.3.0, thus `biopet/v0.3.0` is the module you would want to load.
+
+After loading the module, you can access the biopet package by simply typing `biopet`:
+
+~~~
+$ biopet
+~~~
+
+This will show you a list of tools and pipelines that you can use straight away. You can also execute `biopet pipeline` to show only available pipelines or `biopet tool` to show only the tools. What you should be aware of, is that this is actually a shell function that calls `java` on the system-wide available Biopet JAR file.
+
+~~~
+$ java -jar <path/to/current/biopet/release.jar>
+~~~
+
+The actual path will vary from version to version, which is controlled by which module you loaded.
+
+Almost all of the pipelines have a common usage pattern with a similar set of flags, for example:
+
+~~~
+$ biopet pipeline <pipeline_name> -config <path/to/config.json> -qsub -jobParaEnv BWA -retry 2
+~~~
+
+The command above will do a *dry* run of a pipeline using a config file as if the command would be submitted to the SHARK cluster (the `-qsub` flag) to the `BWA` parallel environment (the `-jobParaEnv BWA` flag). We also set the maximum retry of failing jobs to two times (via the `-retry 2` flag). Doing a good run is a good idea to ensure that your real run proceeds smoothly. It may not catch all the errors, but if the dry run fails you can be sure that the real run will never succeed.
+
+If the dry run proceeds without problems, you can then do the real run by using the `-run` flag:
+
+~~~
+$ biopet pipeline <pipeline_name> -config <path/to/config.json> -qsub -jobParaEnv BWA -retry 2 -run
+~~~
+
+It is usually a good idea to do the real run using `screen` or `nohup` to prevent the job from terminating when you log out of SHARK. In practice, using `biopet` as it is is also fine. What you need to keep in mind, is that each pipeline has their own expected config layout. You can check out more about the general structure of our config files [here](general/config.md). For the specific structure that each pipeline accepts, please consult the respective pipeline page.
+
+### Running Biopet in your own computer
+
+At the moment, we do not provide links to download the Biopet package. If you are interested in trying out Biopet locally, please contact us as [sasc@lumc.nl](mailto:sasc@lumc.nl).
+
+
+## Contributing to Biopet
+
+Biopet is based on the Queue framework developed by the Broad Institute as part of their Genome Analysis Toolkit (GATK) framework. The current Biopet release is based on the GATK 3.3 release.
+
+We welcome any kind of contribution, be it merge requests on the code base, documentation updates, or any kinds of other fixes! The main language we use is Scala, though the repository also contains a small bit of Python and R. Our main code repository is located at [https://git.lumc.nl/biopet/biopet](https://git.lumc.nl/biopet/biopet/issues), along with our issue tracker.
+
+## Local development setup
+
+To develop Biopet, Java 7, Maven 3.2.2, and GATK Queue 3.3 is required. Please consult the Java homepage and Maven homepage for the respective installation instruction. After you have both Java and Maven installed, you would then need to install GATK Queue. However, as the GATK Queue package is not yet available as an artifact in Maven Central, you will need to download, compile, and install GATK Queue first.
+
+~~~
+$ git clone https://github.com/broadgsa/gatk
+$ cd gatk
+$ git checkout 3.3                              # the current release is based on GATK 3.3
+$ mvn -U clean install
+~~~
+
+This will install all the required dependencies to your local maven repository. After this is done, you can clone our repository and test if everything builds fine:
+
+~~~
+$ git clone git@git.lumc.nl:biopet/biopet.git
+$ cd biopet
+$ mvn -U clean install
+~~~
+
+If everything builds fine, you're good to go! Otherwise, don't hesitate to contact us or file an issue at our issue tracker.

-# About biopet
+# About Biopet
 
-## The philosophy
 
-We develop tools and pipelines for several purposes in analysis. Most of them 
-share the same methods. So the basic idea is to let them work on the same 
-platform and reduce code duplication and increase maintainability.
+## The Philosophy
 
-## The Team
-SASC:
-Currently our team exists out of 5 members
+Biopet is meant to be the core framework for data analysis pipelines developed
+by SASC (and collaborators). It consists of wrappers of common command-line tools,
+some production-level data analysis pipelines, and some custom command-line tools
+that we develop in-house.
+
+Pipelines developed using the Biopet framework are meant to be flexible, allowing
+users to modify the actual command line flags of the tools within to suit their
+need.
+
+

- 1. Pipelines to do analysis on sequencing data
- 1. Running analysis on a computing cluster ( Open Grid Engine )
- 1. Running analysis on your local desktop computer
-
-### System Requirements
-
-Biopet is build on top of GATK Queue, which requires having `java` installed on the analysis machine(s).
-
-For end-users:
-
- * [Java 7 JVM](http://www.oracle.com/technetwork/java/javase/downloads/index.html) or [OpenJDK 7](http://openjdk.java.net/install/) 
- * [Cran R 3.1.1](http://cran.r-project.org/)

-## How to use
-
-### Running a pipeline
-
-- Help:
-~~~
-java -jar Biopet(version).jar (pipeline of interest) -h
-~~~
-- Local:
-~~~
-java -jar Biopet(version).jar (pipeline of interest) (pipeline options) -run
-~~~
-- Cluster:
-    - Note that `-qsub` is cluster specific (SunGrid Engine)
-~~~
-java -jar Biopet(version).jar (pipeline of interest) (pipeline options) -qsub* -jobParaEnv YoureParallelEnv -run
-~~~
-- DryRun:
-    - A dry run can be performed to see if the scheduling and creating of the pipelines jobs performs well. Nothing will be executed only the job commands are created. If this succeeds it's a good indication you actual run will be successful as well.
-    - Each pipeline can be found as an options inside the jar file Biopet[version].jar which is located in the target directory and can be started with `java -jar <pipelineJarFile>`
-
-~~~
-java -jar Biopet(version).jar (pipeline of interest) (pipeline options) 
-~~~
-If one performs a dry run the config report will be generated. From this config report you can identify all configurable options.
-
-### Shark Compute Cluster specific
-
-In the SHARK compute cluster, a module is available to load the necessary dependencies.
-
-    $ module load biopet/v0.2.0
-
-Using this option, the `java -jar Biopet-<version>.jar` can be ommited and `biopet` can be started using:
-
-    $ biopet
-
-
-

-
-## Multisample and Singlesample
-### Multisample
-With <a href="https://www.broadinstitute.org/gatk/guide/tagged?tag=multi-sample">multisample</a>
- one can perform variantcalling with all samples combined for more statistical power and accuracy.
-To Enable this option one should enable the following option `"joint_variantcalling":true` in the settings config file. 
-
-
-### Singlesample
-If one prefers single sample variantcalling (which is the default) there is no need of setting the joint_variantcalling inside the config.
-The single sample variantcalling has 2 modes as well:
-
-* "single_sample_calling":true (default)
-* "single_sample_calling":false which will give the user only the raw VCF, produced with [MpileupToVcf](../tools/MpileupToVcf.md)

+# Bam2Wig
+
+## Introduction
+
+Bam2Wig is a small pipeline consisting of three steps that is used to convert BAM files into track coverage files: bigWig, wiggle, and TDF. While this seems like a task that should be tool, at the time of writing, there are no command line tools that can do such conversion in one go. Thus, the Bam2Wig pipeline was written.
+
+## Configuration
+
+The required configuration file for Bam2Wig is really minimal, only a single JSON file containing an `output_dir` entry:
+
+~~~
+{"output_dir": "/path/to/output/dir"}
+~~~
+
+## Running Bam2Wig
+
+As with other pipelines, you can run the Bam2Wig pipeline by invoking the `pipeline` subcommand. There is also a general help available which can be invoked using the `-h` flag:
+
+~~~
+$ java -jar /path/to/biopet.jar pipeline sage -h
+~~~
+
+If you are on SHARK, you can also load the `biopet` module and execute `biopet pipeline` instead:
+
+~~~
+$ module load biopet/v0.3.0
+$ biopet pipeline bam2wig
+
+~~~
+
+To run the pipeline:
+~~~
+ biopet pipeline bam2wig -config </path/to/config.json> -qsub -jobParaEnv BWA -run
+~~~
+
+## Output Files
+
+The pipeline generates three output track files: a bigWig file, a wiggle file, and a TDF file.
