Exon level coverage ratios before and after smoothing. Exon level coverage ratios among tumour and matched normal samples (A, C) before DWT smoothing and (B, D) after DWT smoothing. (A, B) show the ratios against the mean log coverage among the two samples. (C, D) show ratios of chromosome 1 exons against their start locations.
