Plots for filtering splice junctions.

<p>(A) An example, from heart, plotting entropy versus average mismatches for annotated and novel splice junctions. Selected thresholds (0.75 entropy and 1.5 or 1 average mismatches, paired and single-end, respectively) are indicated by the dark lines and the lower right quadrants retained for further splice junction analyses. (B) Plots are for annotated only and novel splice junctions across all tissues for both paired-end and single end data. A vertical dark line indicates the applied threshold of 50 nucleotides. The main graphs are zoomed in to <1000bp intron sizes, while the sub-graphs show all natural log scaled intron sizes.
