Anaconda-Server Badge PyPI version DOI Join the chat at Build Status Build Status

Script of Scripts (SoS) consists of SoS Notebook, a Jupyter-based polyglot notebook that allows the use of multiple Jupyter kernels in one notebook, and SoS Workflow, a workflow system for the execution of workflows in both process- and outcome-oriented styles. It is designed for data scientists and bioinformatics who routinely work with scripts in different languages such as bash, Python, R, and SAS. This repository contains the SoS Workflow workflow engine.

Please refer to relevant publications SoS Notebook: An Interactive Multi-Language Data Analysis Environment in Bioinformatics, Script of Scripts: a pragmatic workflow system for daily computational research in PLoS Computational Biology, and the SoS homepage for more information on SoS Notebook and SoS Workflow.

We welcome and value community contributions: please post issues to provide us feedback or get our support; please send pull requests if you have helped fixing bugs or making improvements to the source code. In addition, if you are interesting in extending SoS, for example adding a new target type or task engine, please have a look at our tutorial on extending SoS here.

Installing SoS Workflow and Notebook

  • If you are using conda, you can install sos using command

    conda install sos -c conda-forge

    You can also install a majority of the SoS suite of tools using commands such as

    conda install sos sos-pbs sos-notebook jupyterlab-sos sos-bash sos-python sos-r -c conda-forge

    This will install SoS Workflow, SoS Notebook and its JupyterLab extension, language modules for Bash, Python2, Python3, R, R itself (r-base and r-irkernel etc) and needed libraries (e.g. feather) if needed.

  • If you are not using conda, you will have to install all the pieces one by one, but you will also have the freedom to use non-conda installation of R, Julia etc. With a working Python 3.6 installation, you can install SoS Workflow with command

    pip install sos

    and also

    pip install sos-pbs

    if you would like to use SoS with a remote batch system such as LSF or Slurm.

    You can install SoS Notebook, and register the sos kernel with Jupyter using the following commands

    pip install sos-notebook
    python -m sos_notebook.install

    To exchange data between live kernels in SoS Notebook, you will need to install individual kernels (e.g. irkernel for R), make sure they work under Jupyter, and install SoS language modules using commands such as

    pip install sos-r sos-matlab sos-python sos-bash

    Different modules might be needed to assist data exchange among kernels. Please refer to the installation page of sos website for details.
