I'm having trouble of understanding the results of rMATS. I ran b1 and b2 files containing RNA-seq. In the first group its BAM files of sick child. In the second group is the BAM files of his healthy parents.

Now I want to see the intron retention events and compare the parents to the child but I don't really understand the output file. What should I look how do I see the overlap? Is there a guide for that?

Thank you
