A user-friendly workflow for analysis of Illumina gene expression bead array data available at the arrayanalysis.org...

Area of Science:

• Transcriptomics and Bioinformatics
• Computational Biology
• Genomics

Background:

• Illumina whole-genome expression bead arrays are a prevalent platform in transcriptomics.
• Existing analysis tools often present challenges for users with limited bioinformatics experience.
• ArrayAnalysis.org is an open-source platform offering a comprehensive interface for R and Bioconductor microarray analysis packages.

Purpose of the Study:

• To develop an accessible, web-based module for the quality control and pre-processing of Illumina bead array data.
• To integrate this module into the ArrayAnalysis.org platform, providing a complete workflow for gene expression data analysis.
• To support a broader user community in analyzing transcriptomics data from Illumina platforms.

Main Methods:

• Development of a new module for the ArrayAnalysis.org platform.
• Implementation of a user-friendly web interface for data upload and analysis.
• Integration with existing statistical and pathway analysis modules within ArrayAnalysis.org.

Main Results:

• A new module provides a free, web-based interface for quality control and pre-processing of Illumina bead array data.
• The module accepts data exported from Illumina's GenomeStudio, generating quality control plots and normalized data.
• Outputs are directly linkable to ArrayAnalysis.org's statistical module or downloadable for third-party analysis.

Conclusions:

• The Illumina bead arrays analysis module is now available on ArrayAnalysis.org, enhancing accessibility for researchers.
• A comprehensive user guide, tutorial, and R scripts are provided to facilitate adoption.
• This module serves as a starting point for statistical and pathway analysis, or for generating processed data for diverse life sciences applications.
