This study introduces reusable software components and algebraic operators for bioinformatics workflows. A prototype tool, GPIPE, enables graphical pipeline generation and analysis reproducibility.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Systems Biology

Background:

  • Computational problem-solving requires integrating information access and algorithm execution within workflows.
  • Bioinformatics workflows are structured using syntactic, semantic, and algebraic objects.
  • Existing graphical user interfaces (GUIs) in bioinformatics offer limited workflow capabilities, with no prior meta-analysis of workflow operators.

Purpose of the Study:

  • To identify common syntactic structures and algebraic operators for bioinformatics workflows.
  • To develop a framework for reusable workflow components and operators.
  • To implement a prototype tool for generating and managing bioinformatics pipelines.

Main Methods:

  • Meta-analysis of existing bioinformatics workflow structures.

    • Identification of common workflow structures and algebraic operators in bioinformatics.
    • Development of a set of generic, reusable workflow components and operators.
    • GPIPE prototype enables pipeline definition, method parameterization, and XML-based metadata storage, extending PISE capabilities.
    • XML-defined analysis protocols facilitate experiment reproduction and sharing.

    Conclusions:

    • Common syntactic structures and algebraic operators for bioinformatics workflows have been identified.
    • These components and operators can be integrated into reusable software modules.
    • The GPIPE prototype facilitates workflow generation and the integration of diverse analytical tools through a GUI builder.
