coronaSPAdes

coronaSPAdes assembles full-length RNA viral genomes, with emphasis on coronaviruses, from short-read sequencing data to improve recovery and characterization of RNA viral species.

Key Features:

• Specialized de novo assembly: Implements de novo assembly tailored for RNA viral genomes from short-read sequencing data to recover single-contig viral sequences.
• Robustness to dataset complexity: Addresses coverage variation, presence of closely related strains, splice variants, and contamination that impede viral assembly.
• Viral genome structure awareness: Incorporates advanced knowledge of viral genome structures into the assembly process to improve reconstruction accuracy.
• Algorithmic lineage: Builds upon methodologies initially implemented in biosyntheticSPAdes within the SPAdes framework.
• Performance in recovery: Comparative analyses report superior recovery of full-length RNA viral genomes versus existing SPAdes modes and other popular short-read metagenome and viral assemblers.

Scientific Applications:

• Viral genome recovery: Reconstruction of full-length RNA viral genomes from complex sequencing datasets.
• Virus identification and characterization: Detection and genomic characterization of viruses, including coronaviruses, in environmental and host-associated samples.
• Virus-host and evolutionary studies: Analyses of virus-host interactions and viral evolution using assembled genomes.
• Epidemiology and surveillance: Support for genomic epidemiology and surveillance efforts through improved viral genome assemblies.
• Support for diagnostics and countermeasure development: Provision of assembled viral sequences to inform diagnostic, vaccine, and therapeutic research.

Methodology:

Performs de novo assembly from short-read sequencing data using algorithms that incorporate viral genome structural knowledge and methodologies derived from biosyntheticSPAdes.
