girafe

girafe represents and analyzes genomic intervals containing aligned reads from next-generation sequencing (NGS) data within the R/Bioconductor environment to enable functional exploration of genome-level alignments.

Key Features:

• Genome-Level Representation: Provides an object class to describe genomic intervals with associated aligned reads, capturing genome-level alignments of NGS data.
• Integration with Bioconductor Framework: Integrates with Bioconductor packages including ShortRead, IRanges, and genomeIntervals to leverage existing data structures and methods.
• Functional Exploration: Enables investigation of genomic intervals together with aligned reads to assess relationships between sequences and genomic features.
• Visualization and Export Capabilities: Includes functions to visualize genomic intervals and associated aligned reads and to export interval data for downstream analysis.

Scientific Applications:

• Genomic Variant Analysis: Examines aligned reads within genomic intervals to identify variants and assess their potential impact on gene function.
• Transcriptome Studies: Analyzes RNA-seq alignments relative to genomic features for transcriptomic investigations.
• Epigenetic Research: Supports examination of sequence reads aligned to regulatory regions such as promoters and enhancers for epigenetic studies.

Methodology:

Implements a genome-interval object class for aligned reads and integrates with ShortRead, IRanges, and genomeIntervals, providing functions for visualization and export.
