An example of a MultiSplice feature. Two ASEs (both are exon-skipping) reside between the clusters π1 and π2. The feature b consists of 5 exons on the path indicated by edge e. Two possible alignments of read r are shown in order for r to span b and confirm the existence of edge e. The possible positions of such alignments then give a sampling window of b (the window bounded by the two light blue lines).
