NGMLR

NGMLR maps third-generation long-read sequencing data from PacBio and Oxford Nanopore to a reference genome to enable accurate alignment of reads that span structural variations.

Key Features:

• Long-read alignment: Aligns PacBio and Oxford Nanopore reads to reference genomes with emphasis on reads spanning structural variations.
• High sensitivity and precision: Detects structural variants, including events in repeat-rich regions and complex nested variants.
• Error management: Implements error correction and filtering mechanisms to reduce false-positive variant calls from high-error-rate long reads.
• Low-coverage compatibility: Operates effectively on low-coverage long-read datasets to support variant detection with reduced sequencing depth.
• Integration with Sniffles: Interfaces with the Sniffles structural variant caller for downstream SV identification.

Scientific Applications:

• Structural variant discovery: Enables discovery of novel structural variants that are difficult to detect with short-read sequencing.
• Human and cancer genomics: Applied to healthy and cancerous human genomes to identify large numbers of previously undetected variants.
• Evaluation of short-read limitations: Helps categorize systematic errors inherent in short-read approaches to improve understanding of genomic structure.
• Low-coverage studies: Supports structural variant analysis in low-coverage long-read sequencing experiments.

Methodology:

Employs alignment algorithms tailored for long-read sequencing and applies error correction and filtering mechanisms to accurately map reads that span structural variations.
