Pathway Tools Software

Pathway Tools is a comprehensive bioinformatics software package that spans enterprise genome data management, systems biology, and omics data analysis. The software has been licensed by more than 12,000 groups and powers and a number of other Pathway/Genome Database websites. The software supports the following operations:

  • Develop organism-specific databases that integrate many bioinformatics datatypes, from genomes to regulatory networks to metabolic and signaling pathways.

  • Computational inferences including metabolic reconstruction and operon prediction.

  • Scientific visualization and dissemination of those organism-specific databases via a public or private website:
    • Multiple search tools
    • Information pages for genes, metabolic pathways, reactions, and metabolites
    • A genome browser, metabolic network browser, and regulatory network browser

  • Analysis suite for gene-expression and metabolomics data.

  • Development of quantitative metabolic models.

  • Comparative genome and pathway analyses.

  • Analysis of biological networks:
    • Search for routes between specified metabolites
    • Find dead-end metabolites
    • Identify choke points (potential drug targets) in metabolic networks
