Effects on mappability on RNA-seq data. A Footprints of mappability scores over all human exons. B Proportion of exons that have an average mappability score above or under the genome average mappability score both for all exons and in 10 groups of exons split on RNA-seq signal (Low..High). Each expression group contain the same number of exons. Groups with significantly (p < 0.001, based on the binomial distribution) higher proportion of low mappability scores than the genome average are marked with an asterisk (*). C In the groups selected as significant in (B), the number of exons with an average of zero (0) mappability scores and non-zero mappability scores are shown.
