ABarray

ABarray performs expression analysis of Applied Biosystems Genome Survey Microarray (AB1700) data within the R statistical environment and the Bioconductor ecosystem.

Key Features:

• Automated Pipeline: Automates processing from raw AB1700 data through to final expression results.
• Data Preprocessing: Implements background correction, normalization, and transformation of microarray probe data.
• Filtering Capabilities: Filters low-quality or unreliable probes from AB1700 datasets.
• Control Probe Analysis: Analyzes control probes to assess assay performance and experimental consistency.
• Statistical Analysis: Performs statistical analyses to identify differentially expressed genes.

Scientific Applications:

• Genomics Research: Analyzes gene expression profiles from AB1700 microarrays to support gene discovery and investigation of regulatory mechanisms.
• Molecular Biology Studies: Detects gene expression changes under different experimental conditions or treatments using AB1700 data.
• Interdisciplinary Research: Integrates with Bioconductor to enable incorporation into broader bioinformatics workflows and cross-disciplinary analyses.

Methodology:

Provides an automated pipeline that performs background correction, normalization, data transformation, probe filtering, control probe analysis, and statistical testing for differential expression, and integrates with other Bioconductor packages.
