While visualizing the gene along with its transcripts, I found that different transcripts started from different genomic coordinates because of the difference in their exons.

For example, for the gene ENSG00000000419 (DPM1), ENST00000413082 (DPM1-204) starts from the right of the other three protein-coding transcripts. As a result, its annotation is also slightly to the right of the other three transcripts.

Without manual intervention, how can I ensure that the annotation for the transcript ENST00000413082 is also along with the other three transcript annotations in this plot? Is there any function argument I can use?

Thanks!

Hi,

What about putting the annotation to the end? They seem to be aligned :)

Unfortunately, I believe there is no way how to achieve it in Gviz without a manual intervention. The names are aligned based on the feature coordinates.

I guess the easiest might be to add some white space in to the name of the last transcript, if you really want to have them aligned.

Best, Robert
