UNITE QIIME release for Fungi 2

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 global and 97% singletons.本次发布三套QIIME格式文件，分别对应以97%和99%相似度阈值聚类得到的SH。第三套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%阈值界定，依此类推；该阈值选择由对应真菌谱系的专家手动确定。三套文件的语法格式保持一致。文件包含全局单例序列及97%相似度阈值下的单例序列。

背景与挑战

背景概述

该数据集为真菌序列数据提供了三组QIIME格式文件，包括基于97%和99%固定聚类阈值的物种假设文件，以及由专家根据真菌谱系动态调整聚类阈值生成的文件。所有文件语法统一，并涵盖全球序列和97%单例序列，适用于真菌多样性分析和生物信息学研究。
