Help to understand group sashimi plot

[Sahu-Mousumi]

Hello
I have a sashimi plot generated for two groups as attached.

What is the difference between average read count 0 (as found for control) and null (in Sc) for exon 2 and 3?

Thank you
MS

If there are no reads for that junction for the group then nothing is shown. If there are reads, but the average count for the group is zero after rounding then 0 is shown
