Chromatin feature patterns. (a,b) Signal pattern (a) and correlation pattern (b) of each chromatin feature in the 160 bins around the TSS and TTS (from 4 kb upstream to 4 kb downstream) of worm transcripts at the EEMB stage. In (a), the signal of each chromatin feature for each bin is averaged across all transcripts. In (b), the Spearman correlation coefficient of each chromatin feature with gene expression levels was calculated for each bin. Ab1 and Ab2 represent experimental results using different antibodies for a chromatin feature. DNA region from 2 kb upstream of the TSS to 2 kb downstream of the TTS is shown in the rectangle.
