GenoMatrix完成马属微生物组16S核糖体RNA（16S rRNA）扩增子数据的系统入库。数据集包含204,007个扩增子序列变体（Amplicon Sequence Variant, ASV）× 2,361个样本的稀疏矩阵，其中588个为有效非零样本。
原始数据经过DADA2流程的严格质控：引物去除、质量过滤、去冗余、嵌合体检测和序列变体推断。最终获得的ASV比传统OTU方法具有更高的分辨率。
588个有效样本涵盖多个马属品种和地理来源，为马属肠道微生物组的品种差异、地理分布和健康关联研究提供了基础数据集。微生物组数据与EQAI现有的基因组数据形成互补——基因组解释"宿主是什么"，微生物组解释"宿主的微生物环境是什么"。
GenoMatrix has completed the systematic import of equine microbiome 16S rRNA amplicon data. The dataset contains a sparse matrix of 204,007 Amplicon Sequence Variants (ASVs) × 2,361 samples, with 588 valid non-zero samples.
Raw data was processed through the DADA2 pipeline with rigorous quality control: primer removal, quality filtering, dereplication, chimera detection, and sequence variant inference. The resulting ASVs offer higher resolution than traditional OTU methods.
The 588 valid samples cover multiple equine breeds and geographic origins, providing a foundational dataset for research on breed differences, geographic distribution, and health associations in the equine gut microbiome. Microbiome data complements EQAI's existing genomic data — genomics explains "what the host is," while microbiomics explains "what the host's microbial environment is."
