Accurate quantification of APA by APAIQ. (A) Correlation of the expression of the PAS predicted by APAIQ and that quantified by 3′ end-seq data. The row indicates cell lines in which the model was trained, whereas the column indicates cell lines in which the prediction was performed. (B) Schematic illustration of the calculation of the error of the PAS usage (PAU) between the prediction from APAIQ and that quantified by 3′ end-seq data. (C) Cumulative plot of the error of PAU predicted by APAIQ and QAPA in the four cell lines.
