BeadDataPackR

BeadDataPackR compresses and provides direct access to raw bead-level data from the Illumina BeadArray platform to enable efficient storage and sharing for genomic analyses.

Key Features:

• Custom Compression Scheme: A bespoke compression algorithm tailored to Illumina BeadArray raw bead-level formats reduces file sizes while preserving data integrity and structure.
• Direct Data Access: Values within compressed files can be queried and manipulated without full decompression, removing a decompression step from analysis workflows.
• Facilitation of Data Sharing: The compression format addresses the random construction of Illumina BeadArray data to produce a more manageable representation for distribution and exchange.

Scientific Applications:

• Cancer research: Enables storage and distribution of Illumina BeadArray raw bead-level data for gene expression profiling, biomarker discovery, and other genomic analyses in oncology studies.
• Meta-analysis and large-scale collaborative projects: Supports aggregation and reanalysis of raw bead-level datasets from multiple sources by reducing file sizes and enabling direct access to compressed data.

Methodology:

A bespoke compression algorithm optimized for Illumina BeadArray raw bead-level data that reduces file size while preserving the ability to directly query and manipulate compressed values without full decompression.
