UNITE QIIME release for Fungi

Three sets of QIIME files are released, corresponding to the SHs resulting from clustering at the 97% and 99% threshold levels. The third set of files is the result of a dynamic use of clustering thresholds, such that some SHs are delimited at the 97% level, some at the 97.5% level, some at the 98% level, and so on; these choices were made manually by experts of those particular lineages of fungi. The syntax is the same throughout the three sets of files. Includes singletons set as RefS (in dynamic files).

本次发布了三组QIIME格式文件，分别对应于以97%、99%相似性阈值聚类得到的物种假设（Species Hypothesis，SH）。第三组文件采用动态聚类阈值策略生成：部分SH以97%阈值界定，部分以97.5%、98%阈值划分，依此类推；该阈值选择由对应真菌类群谱系的专家手动确定。三组文件的格式规范保持一致。动态文件中包含被设置为RefS的单例序列。

背景概述

该数据集为真菌分类提供UNITE QIIME文件，包含三组基于不同聚类阈值（97%、99%和动态专家手动设定阈值）生成的文件，动态阈值文件根据真菌谱系由专家手动调整，并包含单例设置为参考序列。这些文件具有统一的语法格式，适用于真菌多样性研究。
