SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps researchers identify and visualize topologically associating domains (TADs) from Hi-C data stored in .mcool or .cool files, enabling region-specific analyses and interpretability of genome organization.

Core Features & Use Cases

  • TAD calling: automated identification of TAD boundaries using HiCExplorer and related tools.
  • Visualization: generate contact maps with TAD boundaries overlaid for specified loci.
  • Inputs supported: works with .mcool, .cool, or .hic files and requires a genome assembly.

Quick Start

Provide your sample name, mcool file path, and target genome region to run TAD calling and generate visualization outputs.

FAQPage Schema
How do I identify and visualize TADs from Hi-C data in .mcool or .cool files?

To identify TADs from .mcool or .cool files, this skill automates TAD boundary calling using HiCExplorer and overlays the results on contact maps for your specified genomic regions. You simply provide the sample name, file path, target genome assembly, and resolution to generate the visualizations.

What is TAD calling and how does it map topologically associating domains in Hi-C data?

TAD calling is the automated identification of topologically associating domain boundaries from Hi-C contact matrices. This skill uses HiCExplorer to delineate these domains from your input data, enabling region-specific analysis and interpretability of genome organization.

Can I use .hic files for region-specific TAD calling and visualization?

Yes, you can use .hic files for TAD calling and visualization. The skill supports Hi-C data stored in .mcool, .cool, or .hic formats, requiring you to specify a genome assembly, resolution, and target genomic regions to guide the workflow.

What inputs do I need to start automated TAD calling with HiCExplorer?

To start automated TAD calling with HiCExplorer, you need your Hi-C data in .mcool, .cool, or .hic format, a chosen genome assembly, and specified target genomic regions. Providing the sample name and file path initiates the boundary identification and visualization process.

Does this TAD calling workflow support region-specific analyses for specific genome loci?

Yes, this TAD calling workflow supports region-specific analyses by allowing you to specify target genomic regions. It generates contact maps with TAD boundaries overlaid exactly on those user-specified genome loci for focused interpretation.

Why specify resolution when running TAD calling on Hi-C contact maps?

Specifying resolution is required to guide the TAD calling workflow on Hi-C contact maps stored in .mcool or .cool files. The chosen resolution directly impacts the automated identification of TAD boundaries and the resulting visualization of genome organization.
