Edge-linked interval to data view. Edge-linked interval to data view for the expression of the exons of gene PDIA6. The top track shows the expression level for each of the exons, and the color indicates the sample (GM12878 or K562). The second track shows the links between the even-spaced expression track and the exons track, below. The package DEXseq, which produces a similar graphic, computes differential expression and significance, and significance is indicated by coloring the connecting lines red. The track at the bottom shows the annotated transcripts.
