Add exon number
Given a track with mRNA annotations, a new track will be created in which variants are annotated with the numbering of the corresponding exon with numbered exons based on the transcript annotations in the input track (see an example of a result in figure 21.2).
Figure 21.2: A variant found in the second exon out of three in total.
When there are multiple isoforms, a comma-separated list of the exon numbers is given.
