NUCwave

NUCwave generates and analyzes genome-wide nucleosome occupancy maps to characterize nucleosome positioning and its role in genome regulation.

Key Features:

• Multi-method integration: Processes and compares datasets derived from enzymatic digestion, chemical cleavage, and chromatin immunoprecipitation followed by next-generation sequencing (NGS).
• Read alignment: Aligns short-sequence NGS reads to a reference genome and accepts alignment files for downstream analysis.
• Occupancy mapping: Produces high-resolution nucleosome occupancy maps from processed reads and alignment data.
• Comparative analysis: Performs comparative computational analyses across experimental methods and datasets to assess nucleosome positioning differences.
• End-to-end workflows: Supports workflows from raw NGS reads through data processing to computational analysis.
• Compatibility with experimental outputs: Handles common experimental outputs such as NGS reads and alignment files for integration into analyses.

Scientific Applications:

• Genome regulation studies: Map nucleosome positions to elucidate mechanisms of genome regulation and chromatin accessibility.
• Chromatin structure and function: Analyze nucleosome organization to investigate chromatin structure and its impact on regulatory protein access.
• Epigenetic context: Relate nucleosome positioning to epigenetic modifications on histone tails and their regulatory consequences.
• Method comparison and selection: Compare enzymatic digestion, chemical cleavage, and ChIP-derived datasets to inform choice of experimental protocols.

Methodology:

Computational steps explicitly include alignment of short-sequence NGS reads to a reference genome, processing of reads and alignment files, and comparative computational analysis to derive nucleosome occupancy maps.
