Pseudogene mappability and read alignments. (A) Violin plot showing the distribution of gene and pseudogene mappability as a percentage of gene length. The dot in the middle of each plot represents the median, and the black box is the interquartile range. (B) Pie charts showing how many reads are removed by mappability filtering. From left to right: Fraction of all aligned reads that map to pseudogenes; fraction of reads aligned to pseudogenes that are uniquely aligned; and fraction of reads uniquely aligned to pseudogenes that are also mappable.
