OTUrankcurve（RankAbundance曲线）【基本概念】16S结题报告中都会有这么⼀张图：这张图是OTU Rank曲线，该曲线可以展⽰样品的多样性。⽽样品的多样性常通过以下两个⽅⾯ 进⾏解释：物种的丰富程度和均匀程度。Rank曲线中，曲线在横轴上的跨度越长，表明样品的 物种含量越丰富；曲线越平坦，表⽰样品的...

则表明样本中的优势菌群所占比例高,多样性低。 relative abundance:就是该OTU所包含的序列数除以总的序列数,从上图可以看出丰度最高的OTU在10%~100%。 不搞清楚原理,这张图还是很难理解的。 这有点类似于计算N50,把所有OTU按照相对丰度排序,然后一个一个叠加,假设第一个OTU20%,第二个OTU15%,然后依次往后画...

Relative mRNA abundance was calculated by the standard curve method and was normalized by the corresponding amount of mouse Actb (Forward primer; 5′-CTTCTACAATGAGCTGCGTG-3′, Revers primer; 5′-TCATGAGGTAGTCTGTCAGG-3′) or Gapdh (Forward primer; 5′-AATGTGTCCGTCGTGGATCT-3′, Revers ...

relative abundance:就是该OTU所包含的序列数除以总的序列数,从上图可以看出丰度最高的OTU在10%~100%。 不搞清楚原理,这张图还是很难理解的。 这有点类似于计算N50,把所有OTU按照相对丰度排序,然后一个一个叠加,假设第一个OTU20%,第二个OTU15%,然后依次往后画图,连成一条线。
The new model could satisfy the need for more flexible curve-fit models with which differences and changes in the shape of the rank abundance curve can be more accurately investigated. The common rank abundance curve-fit models are lacking that flexibility....
