Watchdog

The development of high-throughput experimental technologies, such as next-generation sequencing, have lead to new challenges for handling, analyzing and integrating the resulting large and diverse datasets. Bioinformatical analysis of these data commonly requires a number of mutually dependent steps applied to numerous samples for multiple conditions and replicates. To support these analyses, a number of workflow management systems (WMSs) have been developed to allow automated execution of corresponding analysis workflows. Major advantages of WMSs are the easy reproducibility of results as well as the reusability of workflows or their components.

Here, we present Watchdog, a WMS for the automated and distributed analysis of large-scale experimental data. Watchdog is implemented in Java and is thus platform-independent.

Watchdog-logo Main features include:

  • straightforward processing of replicate data
  • support for distributed computer systems
  • remote storage support
  • customizable error detection
  • manual intervention into workflow execution
  • a GUI for workflow construction using pre-defined modules
  • a helper script for creating new module definitions
  • no restriction to specific programming languages
  • provides a flexible plugin system for extending without modifying the original sources

New features in Watchdog 2.0:
  • [new] execution: execute only altered or unfinished tasks (resume mode)
  • [new] execution: detach from workflow execution and attach later on (detach/reattach mode)
  • [new] execution: use custom before and after command scripts
  • [new] execution: implementation of XML plugin supporting package managers and virtualizer
  • [new] execution: support of Conda package manager for module dependencies
  • [new] execution: support of Docker container
  • [new] graphical user interface for module creation
  • [new] documentation: standard documentation format for modules
  • [new] documentation: documentation template generator
  • [new] documentation: generation of module reference book
  • [new] reporting: module versioning
  • [new] reporting: retrieval of third-party software versions
  • [new] reporting: create report on workflow execution
  • [new] sharing: community platform for sharing of modules and workflows
