网络分类单元;运筹分类单位;分类单位 网络释义
OTU(operational taxonomic units),即操作分类单元。通过一定的距离度量方法计算两两不同序列之间的距离度量或相似性,继而设置特定的分类阈值,获得同一阈值下的距离矩阵,进行聚类操作,形成不同的分类单元。专业解释太书面不好理解?没事儿,给你举个“栗子”就明白了! 2、OTU在16S测序中有何用? 高通量测序得到的16S序...
楼上正解。operational taxonomic units是可操作分类单元，说白了，就是根据基因测序结果对微生物进行分类...
可执行的分类操作单位，主要是按照16sDNA测序结果计算遗传距离，人为规定遗传距离，然后依此距离区别微生物...
