Data statistics

On this page, you can explore an interactive PCA (Principal Component Analysis) plot that reveals the overall trend of the data. Additionally, you'll find a statistical table detailing the primary data used to construct the database. To view the GTEx SRR sample names, simply hover your mouse over the PCA plot.

a Samples were filtered out using the overall alignment rate of Hisat2 (<80%). b Tissue-specificity of a gene was determined by Mann-Whitney U test for transcriptional expressions of each gene across tissues. c The p-value of mutual information score was calculated in 100 bootstrap consolidation for indicating
