Significant enrichment for expression among CRS predictions. Expression is defined by a minimum number of modENCODE tiling experiments that show expression (x axis). As background we used 10 samples of randomly selected genomic loci of the same size and number as CRS predictions. The analysis was performed unfiltered (a) and filtered to exclude CRSs and genomic samples overlapping protein-coding and UTR exons (≥1 bp) to avoid mRNA exon bias (b). Significance of the enrichment of expressed CRSs is determined by the highest p-value from 10 samples calculated by Fisher’s exact test
