HASLR

HASLR assembles genomes by combining long reads from Oxford Nanopore Technologies and Pacific Biosciences with short Illumina reads to produce accurate, contiguous de novo assemblies and support structural variant analysis.

Key Features:

• Hybrid Assembly Approach: Combines long reads from Oxford Nanopore Technologies and Pacific Biosciences with short reads from Illumina to span repeats and improve assembly contiguity.
• Speed and Efficiency: Processes large genomes rapidly, exemplified by assembling a CHM1 human dataset in under 10 hours using 64 CPU threads.
• Accuracy and Contiguity: Produces highly contiguous assemblies with a low number of misassemblies relative to other tested assemblers.
• Computational Efficiency: Balances speed and accuracy to enable assembly of both small and large genomes on a single computing node.

Scientific Applications:

• De novo assembly: Performs de novo genome assembly using hybrid long- and short-read data.
• Structural variant detection: Generates assemblies that resolve complex and repetitive regions to support structural variant analysis.
• Comparative genomics: Produces accurate, contiguous assemblies suitable for comparative genomics studies.

Methodology:

Employs a hybrid strategy that integrates long reads to span repetitive regions while using short reads for error correction and increased accuracy.
