Explore Earth’s Virome with Serratus. We uncover 130,000+ new species of RNA viruses, increasing the total known species by an order of magnitude. (Thread) Serratus is an open-source cloud-compute based alignment infrastructure. With it, we aligned 5.7 million sequencing libraries (10.2 petabases) against a collection of all viral RNA-dependent RNA Polymerases to rapidly expand the limits of known RNA viruses.
