Researchers at the Earlham Institute released MARTi, an open‑source software suite that performs real‑time analysis and visualization of nanopore metagenomic data for pathogen detection, antimicrobial resistance gene surveillance and environmental monitoring. MARTi runs from laptops to HPC systems and supports classifiers such as BLAST, Centrifuge and Kraken2, enabling flexible in‑field or lab workflows. Authors demonstrated MARTi across clinical, agricultural and marine settings, emphasizing its lightweight operational footprint and browser‑based GUI for rapid interpretation. The tool builds on prior rapid‑pathogen identification pipelines and extends them with visualization and customizable databases for diverse use cases. MARTi’s availability as open‑source software aims to lower technical barriers for time‑sensitive metagenomics and accelerate responses to emerging microbial threats.
