Researchers at the Earlham Institute released MARTi, an open‑source software suite that enables real‑time analysis and visualization of nanopore metagenomic data. MARTi runs on standard laptops or HPC clusters, supports multiple classifiers (BLAST, Centrifuge, Kraken2), and provides a browser GUI for immediate taxonomic and antimicrobial‑resistance gene reporting. Developers adapted MARTi from neonatal pathogen‑surveillance tools and demonstrated its use on research vessels, agricultural sites and clinical samples. The software’s operational lightness and visualization capabilities aim to shorten detection-to‑response timelines in outbreak, biosurveillance and environmental monitoring contexts. MARTi’s release may accelerate adoption of nanopore sequencing for time‑sensitive microbial threat detection and supports decentralized genomic surveillance workflows.
