The data used by the "co-expression" network is the same as that used in the "Expression profile" page. The co-expression network was obtained by calculating the Pearson correlation coefficient (r2) of the gene pairs side by side, and the final gene pairs r² > 0.8 were retained. Finally, we obtained 17,013,938 co-expressed gene pairs involving 33,654 genes. In addition, combined with the TF annotations, we obtained 1,626 TFs and 36,222 regulated genes, and obtained 2,036,569 TF-gene pairs.
