Background:

  • Quantitative trait loci (QTL) mapping is crucial for understanding the genetic basis of complex traits.
  • Existing QTL mapping tools often lack scalability and flexibility for diverse data types.

Purpose of the Study:

  • To introduce xQTL workbench, a scalable web platform for multi-level QTL analysis.
  • To provide accessible QTL mapping methods for various populations and data types.

Main Methods:

  • Web-based platform utilizing the Molgenis software generator for customization.
  • Supports diverse data types including gene expression, protein abundance, metabolite abundance, and phenotype data.
  • Scalable architecture for multi-core computers, clusters, and cloud environments.

Main Results:

  • xQTL workbench enables scalable QTL mapping for gene expression (eQTL), protein abundance (pQTL), metabolite abundance (mQTL), and phenotype (phQTL).
  • Accommodates various data formats such as microarrays, NGS, LC-MS, GC-MS, and NMR.
  • Accessible via a web user interface with online data upload and querying capabilities.

Conclusions:

  • xQTL workbench offers a flexible and scalable solution for multi-level QTL analysis.
  • Facilitates the integration and analysis of diverse biological data for genetic studies.
  • The platform is customizable for emerging data types, enhancing its long-term utility.
