LoReTTA

LoReTTA assembles de novo viral genomes from long-read PacBio sequencing data to produce accurate and contiguous assemblies for viral genomics analyses.

Key Features:

• Reference-Assisted Assembly: Leverages a reference genome to guide de novo assembly of long-read data, adapting reference-assisted strategies from short-read assembly to improve accuracy and contiguity.
• Optimized for Viral Genomes: Tailored to handle viral genome complexities including high genetic diversity, multiple isoforms, and the potential presence of co-occurring organisms in clinical or environmental samples.
• Performance Superiority: Demonstrated superior assembly contiguity and accuracy relative to established long-read assemblers in comparative evaluations using simulated and experimental PacBio datasets.

Scientific Applications:

• Pathogen Identification: Enables reconstruction of viral genomes for pathogen identification from clinical and environmental samples.
• Evolutionary Analysis: Provides assemblies suitable for evolutionary and phylogenetic analyses of viruses.
• Viral Diversity Characterization: Facilitates characterization of viral diversity and detection of co-infecting organisms in complex samples.

Methodology:

Performs reference-assisted de novo assembly adapted for long-read data and was evaluated via comparative analyses on simulated and experimental datasets measuring assembly contiguity and accuracy.
