Architecture and implementation of ulrb algorithm in R, source data

This dataset makes available the source data used for all analyses made in the original research article entitled "Architecture and implementation of ulrb algorithm in R", for the journal Ecological Informatics.

Short description of files:
nice_ASVs.csv - ASV abundance table in long format;
nice_otu_long - OTU abundance table in long format;
nice_otu_wide - OTU abundance table in wide format.

All files correspond to samples collected from seawater of the Arctic Ocean, during the Norwegian Young Sea Ice Expedition, using V4V5 16S rRNA gene amplicon sequencing.

本数据集公开了发表于《生态信息学》期刊、题为《R语言中ulrb算法（ulrb algorithm）的架构与实现》的原创研究论文中所有分析所用的源数据。

文件简要说明：
nice_ASVs.csv：长格式扩增子序列变异体（Amplicon Sequence Variant, ASV）丰度表；
nice_otu_long：长格式操作分类单元（Operational Taxonomic Unit, OTU）丰度表；
nice_otu_wide：宽格式OTU丰度表。

所有文件中的样本均采集自北冰洋海水，采集工作依托挪威年轻海冰科考项目完成，测序采用V4V5区16S rRNA基因扩增子测序技术。
