Metagenome宏基因组,未识别的物种unclassified

1："Bacteria|Proteobacteria|Betaproteobacteria|Neisseriales|Neisseriaceae|Kingella"                     2："Bacteria|Proteobacteria|Betaproteobacteria|Neisseriales|Neisseriaceae|unclassified"

# 未识别到的/未注解到的物种，不可以在OTU/ASV表中直接删掉，识别到的水平 ，例如把上面的第2个，删除成“Bacteria|Proteobacteria|Betaproteobacteria|Neisseriales|Neisseriaceae”，这科水平Bacteria|Proteobacteria|Betaproteobacteria|Neisseriales|Neisseriaceae，代表的是底下所有合并的情况。不允许单独去掉未识别到的那部分。

在进行物种进化树或者cladogram或者GraPhlAn绘制
