beadarray

beadarray processes Illumina BeadScan bead-level data and BeadStudio bead-summary data within R/Bioconductor for preprocessing, quality assessment, and summarization of Illumina microarray experiments.

Key Features:

• Data Compatibility: Supports raw TIFF images and text files from Illumina BeadScan and bead-summary data from BeadStudio.
• Bead-level Data Handling: Reads, stores, and processes bead-level data generated by Illumina BeadScan technology.
• Image Processing, Background Correction, and Normalization: Provides multiple methods for image processing, background correction, and normalization of bead-level data.
• Quality Assessment: Includes tools for assessing the quality and integrity of raw bead-level and summarized data.
• Data Summarization and Bioconductor Compatibility: Summarizes processed data and stores results in formats compatible with other R/Bioconductor packages.

Scientific Applications:

• Gene Expression Analysis: Preprocessing, quality control, and summarization of Illumina microarrays for gene expression studies.
• SNP Genotyping: Processing and quality assessment of BeadArray data used for SNP genotyping on Illumina microarrays.
• Methylation Profiling: Preprocessing and summarization of Illumina methylation BeadArray data for downstream analysis.

Methodology:

Reads and stores Illumina BeadScan TIFF and text files and BeadStudio bead-summary data, performs image processing, background correction, normalization, quality assessment, and summarizes data using R and Bioconductor functions.
