Fig. 4From: APA-Scan: detection and visualization of 3′-UTR alternative polyadenylation with RNA-seq and 3′-end-seq dataEvidence of polyadenylation sites supported by 3′-end-seq data for 3′-UTR APA events detected by different methods in MEFs samples. The number of events predicted by each method are shown in purple and the number of events validated by the signals in the 3′-end-seq data are shown in blue. The x-axis shows the percentage of the identified events is validated by 3′-end-seqBack to article page
