metabuli

metabuli integrates DNA and amino acid (AA) sequence analyses to improve metagenomic taxonomic classification by enhancing homology detection sensitivity and taxonomic specificity.

Key Features:

• Joint DNA and Amino Acid Analysis: Combines DNA sequence information with amino acid (AA) conservation patterns to increase sensitivity in homology detection.
• Differentiation of Closely Related Taxa: Incorporates DNA mutations to refine taxonomic distinctions and improve specificity between closely related organisms.
• High Coverage on CAMI Dataset: Covered 99% of classifications achieved by state-of-the-art DNA-based classifiers and 98% of those by AA-based classifiers on the CAMI plant-associated dataset.

Scientific Applications:

• Metagenomic Taxonomic Classification: Provides integrated DNA and AA evidence to support accurate taxonomic assignments in metagenomic samples.
• Plant-Associated Microbiome Analysis: Applicable to plant-associated microbiomes, as demonstrated by performance on the CAMI plant-associated dataset.
• Ecology, Agriculture, and Environmental Studies: Supports investigations of microbial community composition and dynamics in ecological, agricultural, and environmental contexts.

Methodology:

Processes DNA and amino acid sequences concurrently, leveraging amino acid evolutionary conservation to enhance homology detection while using DNA sequence variation to refine taxonomic distinctions.
