diffloop

diffloop identifies and analyzes differential DNA looping between samples to study three-dimensional chromatin architecture and its effects on gene expression.

Key Features:

• Differential Loop Identification: Detects variations in DNA loop structures between samples.
• Quality Control: Provides functions for quality control of chromatin loop data.
• Statistical Testing: Implements statistical testing to compare looping patterns across samples.
• Annotation: Annotates DNA loops with genomic context and features.
• Visualization: Generates visual representations of chromatin loops and differential results.

Scientific Applications:

• ChIA-PET and related assays: Analysis of ChIA-PET and similar chromatin interaction datasets to infer chromatin loops.
• Linking loops to regulation: Exploring how differences in loop structures relate to epigenetic states and gene expression profiles.
• ENCODE ChIA-PET analysis: Applied to ENCODE ChIA-PET datasets to connect looping patterns with biological phenomena.

Methodology:

Computational steps include quality control measures, statistical analyses, and visualization tailored for chromatin loop data.
