Shotgun metagenomic sequencing of human fecal Y2 (CRX2118837)
DNA for each sample was extracted with FastDNA SPIN Kit (MP Biomedicals), sheared to approximately 300-500 bp using a Covaris S220 instrument. Then the libraries were constructed through end-repair, A-tailing, adapter ligation. Then it was sequenced on BGISEQ-500 platform in PE100 mode
