I have received the RNAseq data outcomes as alternative splicing and differentially alternative splicing in excel files

For Alternative splicing, there are data for each sample as the following

· Alternative 5' Splicing Site(A5SS)

· Alternative 3' Splicing Site (A3SS)

· Mutually exclusive exons (MXE)

· Retained Intron (RI)

· Skipped Exon (SE)

And this is the detail of Retained Intron (RI) this is excel file format as in photo 1

For differential Alternative splicing, there are data for each group (control and test) as the following

· Alternative 5' Splicing Site (A5SS)

· Alternative 3' Splicing Site (A3SS)

· Mutually exclusive exons (MXE)

· Retained Intron (RI)

· Skipped Exon (SE)

And this is the detail of Retained Intron (RI) ) this is excel file format as in photo 2

Abbreviation in photo1,2

SC: The number of reads across the skipping junction, repeated samples are separated by semicolons

IC: The number of reads across the inclusion junction, repeated samples are separated by semicolons

PLEASE I need suggestions from the expertise of RNAseq data interested scientists, On how to estimate IR from that data that I have?
