title: Metagenome or environmental sample from methane-seep metagenome D517ROV2PC203-15cm
design: Sequencing libraries were generated using NEBNext Ultra DNA Library Prep Kit for Illumina (NEB, Ipswich, MA, USA) and sequenced using a NovaSeq 6000 platform (Illumina, San Diego, CA, USA). Clean data (150-bp paired-end reads) were obtained by removing adapters, barcodes, reads containing poly-N, and low-quality reads from the raw data.
