3d-dna

3d-dna generates chromosome-length genome assemblies by scaffolding draft assemblies using Hi-C chromosome conformation capture data.

Key Features:

• Hi-C–Based Scaffolding: Uses high-throughput chromosome conformation capture (Hi-C) interaction data to organize draft genome assemblies into chromosome-length scaffolds.
• Integration with Short-Read Assemblies: Combines Hi-C contact information with existing short-read draft assemblies to improve genome structure reconstruction.
• Chromosome-Level Assembly Reconstruction: Produces large scaffolds corresponding to individual chromosomes in assembled genomes.
• Structural Genome Organization Analysis: Enables identification of large-scale genomic arrangements and chromosomal rearrangements within assembled genomes.

Scientific Applications:

• De Novo Genome Assembly: Supports construction of chromosome-scale genome assemblies from draft sequencing data.
• Comparative and Structural Genomics: Facilitates analysis of chromosomal organization and structural rearrangements across species.
• Vector and Model Organism Genomics: Enables assembly and analysis of genomes such as *Aedes aegypti* and *Culex quinquefasciatus*.

Methodology:

The pipeline integrates Hi-C contact maps with draft genome assemblies derived from short-read sequencing data to scaffold contigs into chromosome-length assemblies based on spatial interaction patterns.
