Distribution of annotated sequences.

Reads were classified through bovine coronavirus mapping and blastx. The table shows percentage of reads from the ovation (O) and SISPA (S) samples that mapped to bacteria, archaea, eukarya and virus.测序读段（reads）通过牛冠状病毒比对与BLASTx工具完成分类。本表格展示了来自ovation（O）与SISPA（S）样本的读段，比对至细菌、古菌、真核生物与病毒的占比。
