RefEx2 Datasets for Human GTEx v8

RefEx2 is a project to collect, organize, and curate transcriptome datasets of various species as reference resources for gene expression data analysis. It provides 6 reference datasets for four different species: humans, mice, Drosophila melanogaster, and Arabidopsis thaliana. This directory contains the following datasets on human GTEx v8:220404_gtex_v8_refextable_sample_stats.tsv.gzProcessed data matrix220404_gtex_v8_summarized_refextable_sample_stats.tsv.gzProcessed data matrix (summarized ver.) gtex_v8_refextable_grouped_sample_desc.tsvGrouped sample descriptiongtex_v8_summarized_refextable_grouped_sample_desc.tsvGrouped sample description (summarized ver.) gtex_v8_refextable_sampleID_mapping.tsvSample ID mappingsgtex_v8_summarized_refextable_sampleID_mapping.tsvSample ID mappings (summarized ver.)

RefEx2是一项旨在收集、整理并经过人工质控甄选的各类物种转录组数据集的项目，作为基因表达数据分析的参考资源。该项目为四个不同物种——智人、小家鼠、黑腹果蝇、拟南芥——提供了6套参考数据集。本目录包含针对人类GTEx v8的如下数据集：
1. 220404_gtex_v8_refextable_sample_stats.tsv.gz：经处理的样本统计数据矩阵
2. 220404_gtex_v8_summarized_refextable_sample_stats.tsv.gz：简化版经处理的样本统计数据矩阵
3. gtex_v8_refextable_grouped_sample_desc.tsv：分组样本描述文件
4. gtex_v8_summarized_refextable_grouped_sample_desc.tsv：简化版分组样本描述文件
5. gtex_v8_refextable_sampleID_mapping.tsv：样本ID映射文件
6. gtex_v8_summarized_refextable_sampleID_mapping.tsv：简化版样本ID映射文件
该数据集包含基因56161个，样本638个；核心标识符为Ensembl基因（Ensembl gene）；原始数据为GTEx_Analysis_2017-06-05_v8_RNASeQCv1.1.9_gene_tpm.gct.gz；参考文献为DOI: 10.1126/science.aaz1776。
