UMI4Cats

UMI4Cats processes, analyzes, and visualizes UMI-4C chromatin contact data to quantify and compare targeted chromosomal interactions using unique molecular identifiers (UMIs) and chromosome conformation capture (4C).

Key Features:

• R package implementation: Implemented as an R package for computational analysis of UMI-4C data.
• Data processing: Processes raw sequencing FastQ files into analyzable formats.
• Bias removal: Uses UMIs to mitigate PCR duplication bias in UMI-4C datasets.
• Differential contact detection: Implements two statistical methods for identifying differential chromatin contacts between experimental conditions.
• Visualization tools: Provides functions to plot integrated information from UMI-4C assays.

Scientific Applications:

• 3D chromatin architecture: Studies three-dimensional chromatin organization and its implications for gene regulation.
• Differential interaction analysis: Compares chromatin contacts across conditions such as disease states or developmental stages.

Methodology:

Processes raw FastQ sequencing data, integrates UMIs with 4C to reduce PCR amplification bias, applies two statistical methods to detect differential chromatin contacts, and produces plots of integrated UMI-4C information.
