DLO Hi-C

DLO Hi-C processes and analyzes Digestion-Ligation-Only Hi-C (DLO Hi-C) sequencing data to produce normalized contact maps that support studies of three-dimensional genome organization and long-range gene regulation.

Key Features:

• Efficient Data Processing: Transforms raw sequencing reads into normalized contact maps for whole-genome chromosome conformation analysis.
• Iterative Mapping and Linker Filtering: Implements iterative mapping and linker filtering to improve read alignment and contact assignment accuracy.
• Quality Control Measures: Performs quality control at multiple processing stages to assess data integrity and processing outcomes.
• Multithreading Capability: Uses multithreading to parallelize computation for large DLO Hi-C datasets.
• Support for DLO Hi-C Variants: Handles both standard DLO Hi-C and in situ DLO Hi-C dataset types.

Scientific Applications:

• Three-dimensional genome organization: Generates contact maps used to analyze chromatin architecture and spatial chromosome arrangements genome-wide.
• Long-range gene regulation: Enables identification of regulatory element–target gene interactions across long genomic distances using chromosome conformation data.

Methodology:

Computational steps explicitly include transforming raw sequencing reads into normalized contact maps, iterative mapping, linker filtering, multistage quality control, and multithreaded processing.
