Dear BioCiphers community, 

I am still new to majiq and I’m having some difficulty interpreting certain elements of the Voila visualization (screenshot attached). Do you mind helping me with the following questions?

  1. The dotted splice junction lines are labeled as “DB only.” Do these refer to the Ensembl annotations provided in the GFF3 file?

  2. What does the single short line extending after exon 13 represent?

  3. What is the meaning of the small block shown below exon 11?

  4. Why does the red junction line near exon 6 (classified as DB & RNASeq) not display any median read support?

  5. Is it expected that the number of exons displayed in the Voila visualization often exceeds the number of exons in any individual transcript annotation?


Thank you so much for all your support! Would appreciate your help. 

All the best,
Alex
