自适应采样是纳米孔测序平台特有的一种软件控制的浓缩方法。为了测试它在元基因组样本中丰富稀有物种的潜力,我们创建了一个合成模拟社区,并构建了具有一定平均阅读长度范围的测序文库。对于最长阅读长度文库中丰度最低的物种,浓缩倍数高达13.87倍;考虑到拒绝分子导致的产量减少,计算效率将其提高到4.93倍。最后,我们介绍了一个基于分子长度和相对丰度的浓缩数学模型,其预测与模拟和复杂的真实世界微生物群落密切相关。网上版载有补充材料,可在10.1186/s13059-021-02582-x查阅。
Adaptive sampling is a method of software-controlled enrichment unique to nanopore sequencing platforms. To test its potential for enrichment of rarer species within metagenomic samples, we create a synthetic mock community and construct sequencing libraries with a range of mean read lengths. Enrichment is up to 13.87-fold for the least abundant species in the longest read length library; factoring in reduced yields from rejecting molecules the calculated efficiency raises this to 4.93-fold. Finally, we introduce a mathematical model of enrichment based on molecule length and relative abundance, whose predictions correlate strongly with mock and complex real-world microbial communities.
