MetaG

MetaG classifies metagenomic short and long sequencing reads to identify organisms and extract associated metadata such as host information and antibiotic resistance profiles.

Key Features:

• High classification accuracy: Demonstrated nearly perfect classification performance for viral isolates using simulated short and long reads.
• Targeted rRNA gene support: Outperforms state-of-the-art algorithms on targeted 16S and 28S rRNA gene sequencing data.
• Comprehensive outputs: Provides taxonomic assignments and reports potential host and antibiotic resistance profiles of pathogens.
• Short- and long-read support: Processes both short-read and third-generation long-read sequencing data.
• Robustness to long-read errors: Employs methods that maintain high accuracy despite reduced per-base accuracy associated with longer molecule sequences.

Scientific Applications:

• Environmental Microbiology: Identifies organisms in complex environmental samples to support studies of microbial diversity and ecosystem dynamics.
• Healthcare: Detects pathogens and extracts host and antibiotic resistance information to inform infection control and diagnostic efforts.
• Microbial Ecology: Enables detailed taxonomic profiling for research on microbial interactions and community structure.

Methodology:

MetaG uses advanced algorithms tailored to the challenges of third-generation long-read sequencing, designed to maintain high accuracy in organism classification and to extract taxonomic assignments and metadata (host and antibiotic resistance) from metagenomic sequences.
