Splicing summary with coordinate truncate gaps. An example of a plot madefrom multiple tracks. At the top, the relevant chromosome is drawn with thesubregion of interest marked in red. The middle track shows the slicing summaryplots for the gene ALDOA for normal and tumor samples. Splicing is shownas arches and size is used to represent junction counts and color representsnovelty: blue indicates known splicing events against the model and red indicatesnovel splicing events. The height of arches is proportional to the distancebetween the two ends of the arches, or the distance between the junction reads.Coverage is shown by position to address supporting evidence in the raw data. Thesplicing summary plots are aligned with a view of the gene structure in the bottomtrack. The thicker rectangle represents the Consensus Coding DNA Sequence (CCDS)transcripts. The plots in both tracks are made with truncate gaps coordinatetransformation. The space dedicated to introns has been significantly reduced, andthe exonic regions are shown in detail, even though the entire gene region is inview.
