GGtools

GGtools performs genome-wide microarray-based analyses to link DNA polymorphisms, including Phase II HapMap genotypes, with mRNA abundance and DNA methylation using R/Bioconductor-compatible frameworks.

Key Features:

• Data architecture and algorithm interfaces: Provides flexible data architectures and algorithm interfaces for genotyping and expression array data.
• R/Bioconductor integration: Integrates with R/Bioconductor to leverage statistical methods and analysis frameworks.
• Phase II HapMap genotype support: Supports Phase II HapMap genotypes as an input genotype resource.
• Illumina 47K expression assay support: Supports data derived from the Illumina 47K expression assay for transcriptomic measurements.
• Microarray-based genome- and transcriptome-wide surveys: Performs genome-wide and transcriptome-wide surveys using microarray technology.
• Association analysis of polymorphisms and expression: Analyzes associations between DNA polymorphisms and mRNA abundance.
• DNA methylation analysis support: Includes functionality for genetic analysis of DNA methylation alongside gene expression.

Scientific Applications:

• Genetic association studies: Investigation of associations between DNA polymorphisms and mRNA abundance to study gene regulation.
• Population genetics analyses: Comparative analyses of genetic and expression data across multiple populations.
• Transcriptome-wide surveys: Comprehensive analysis of gene expression patterns across the transcriptome.
• Integrative studies of expression and methylation: Combined analysis of gene expression and DNA methylation to inform functional genomics and disease-related mechanisms.

Methodology:

Employs advanced data processing techniques to manage and analyze large-scale genetic and expression microarray datasets and integrates with R/Bioconductor to apply statistical methods and visualization tools.
