WAW (Workflow Application Wrapper) is a framework for automatic generation of workflows. It allows users to generate a workflow and its execution environment, and use it with or without a graphical interface on various infrastructures (personal machine, server, cluster, cloud, etc.). The framework includes 100 bioinformatics application bricks that can be assembled to create a wide variety of analysis workflows. It is built on existing technologies such as Snakemake, Docker, R Shiny, conda, and MultiQC.
