丰度等级曲线(Rank abundance curve)在群落分析中,可以直接反应群落中高丰度和稀有ASV/OTU的数量,该曲线将每个样品的按其丰度大小延横坐标依次排列,并以各自的丰度值为纵坐标,用折线或曲线将各asv/otu互相连接,从而反应各样本中ASV/OTU丰度的分布规律。 该曲线使用R脚本绘制起来也比较简单,调用ggplot2包即可绘,具体...

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...

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...
Rank-abundance curvesFriedemann Goral
[7, 25], the chemical gas composition and the ratio of the abundance of CH4relative to higher hydrocarbons (i.e., “gas dryness”) became indispensible proxies for evaluating the origin of coalbed gas[26–30](Table 1a.1). However, these chemical compositional indices may vary significantly,...
The calibration curve is obtained by drawing a smoothed line through these points using lowess [13] as implemented in R (the default smoother span used with GSRN is 0.25, but this value may be adjusted if needed). The vertical displacement between the smoothed calibration curve and the ...
