Characterizing the correlations between peak intensity and gene expression of nearby genes. a and c The number of genes regulated by one peak, and the number of peaks regulated one gene. The X-axis of the histogram represents different groups that were classified according to the associated gene (peak) numbers per peak (gene), and the Y-axis represents the gene (peak) count for each group. Positive peak - gene pairs and negative peak - gene pairs are distinguished by different colors. b Bar plot of the relationship between the correlation and distance of peak - gene pairs. d Distribution of the distance for significant positive peak - gene pairs and negative peak - gene pairs. e and h Heatmap of tissue-specific peaks (genes) from all significant peak - gene pairs. f Representative examples of a significant tissue-specific peak - gene pair which peak and gene are both tissue-specific. The dots represent peak intensity and gene expression from each sample. Different colors indicate different tissue types. g An representative examples of a significant conserved peak - gene pair. The peak and gene are both expressed ubiquitously across tissues. The dots represent peak intensity and gene expression from each sample. Different colors indicate different tissue types
