Trycycler

Trycycler generates consensus bacterial genome assemblies from multiple long-read assemblies to reduce errors introduced by long-read sequencing.

Key Features:

• Consensus Assembly Generation: Integrates multiple individual assemblies produced by different assembly algorithms into a single consensus assembly to lower error rates.
• Benchmarking Performance: Empirical benchmarking shows consensus assemblies have significantly reduced error rates compared with assemblies produced by a single automated method.
• Post-Assembly Polishing: Supports post-assembly polishing to further reduce sequence errors in the consensus assembly.
• Manual Intervention Requirement: Incorporates user-guided manual steps that yield non-deterministic outputs, with different users tending to produce similar consensus assemblies.

Scientific Applications:

• Microbial genomics: Produces high-fidelity bacterial genome sequences for microbial genomics research.
• Evolutionary biology: Enables accurate genome-based analyses in evolutionary biology.
• Pathogen surveillance: Improves the reliability of genome sequences used in pathogen surveillance.
• Antibiotic resistance, virulence and diversity studies: Facilitates detection and characterization of antibiotic resistance genes, virulence factors, and microbial diversity.

Methodology:

Integrates multiple long-read assemblies to form a consensus sequence, leverages assemblies from different assembly algorithms, requires user input at various stages, and supports post-assembly polishing.
