SRX18337398: Metagenomic sequencing of ZymoBIOMICS HMW DNA Standard using VolTRAX
1 OXFORD_NANOPORE (MinION) run: 2.9M spots, 26.9G bases, 22.1Gb downloads

Design: We used 1 ug of the HMW DNA standard as input for the VolTRAX V2 (ONT) to prepare a sequencing library (VSK-VSK002 workflow). We sequenced the prepared library using the MinION mk1b (ONT) on a r9.4.1 flow cell (FLO-MIN106) for 48 hours (VSK002 script). We basecalled the reads using Guppy version 5.0.7 with the super-accuracy model (-c dna_r9.4.1_450bps_sup.cfg).

Study: Accuracy and completeness of long read metagenomic assemblies
show Abstracthide Abstract
Metagenomics has can be used as a tool to explore the interactions between microbes. Metagenomic assemblies built using long read nanopore data depend on the read level accuracy. The read level accuracy of nanopore sequencing data has made dramatic improvements over the past several years. However, we do not know if the increased read level accuracy allows for faster assemblers to make as accurate metagenomic assemblies as slower assemblers. Here, we present the results of a benchmarking study comparing three commonly used long read assemblers, Flye, Raven, and Redbean. We used a prepared DNA standard of seven bacteria as our input community. We prepared a sequencing library on the VolTRAX V2 sequence using a MinION mk1b. We basecalled using the latest version of Guppy with the super-accuracy model.
