Hazard Analysis and Critical Control Points (HACCP)01:30

Hazard Analysis and Critical Control Points (HACCP)

Hazard Analysis and Critical Control Points (HACCP) is a science-based, preventive system used globally to ensure food safety by identifying, evaluating, and controlling biological, chemical, and physical hazards throughout food production. Originally developed by NASA and the Pillsbury Company for astronaut food, HACCP is now a core component of the Codex Alimentarius.HACCP operates on prerequisite programs—such as Good Manufacturing Practices (GMPs), sanitation procedures, and supplier...

  • Computational Biology

Background:

  • High-throughput chromosome conformation capture (Hi-C) technology generates vast amounts of sequencing data.
  • Existing tools effectively create Hi-C contact maps but lack functionalities for querying and extracting biological information.
  • A need exists for specialized tools to analyze and interpret Hi-C datasets for biological insights.

Purpose of the Study:

  • To develop and present HiCmapTools, a novel software solution for efficient Hi-C map analysis.
  • To provide biologists with a tool for querying Hi-C contact maps to extract meaningful biological information.
  • To validate the utility of HiCmapTools on key biological questions such as TAD loops and intra-TAD density.

Main Methods:

  • Development of HiCmapTools, a comprehensive software package implemented in C++ and R.
  • Integration of multi-query modes and diverse analysis tools within the software.
  • Validation of the tool's performance using real biological datasets addressing specific genomic architecture questions.

Main Results:

  • HiCmapTools enables efficient calculation and analysis of Hi-C maps.
  • The software offers multi-query capabilities and various analysis functions.
  • Successful validation on biological questions including TAD loop identification and TAD intra-density analysis.

Conclusions:

  • HiCmapTools provides biologists with seven access options for quantifying contact frequencies at specific genomic sites.
  • The tool facilitates the extraction of biological information from Hi-C datasets.
  • HiCmapTools is freely available with comprehensive documentation for widespread adoption and use.
