STAR total splices (in Log.final) vs collapsed splice junctions (in SJ.out.tab)

Question

[tnminh89]

Hi everyone,

I am very new to STAR alignment and confused about the difference between total splices (in Log.final) vs collapsed splice junctions (in SJ.out.tab). How can I interpret the results biologically based on these (what do total splices tell me and what do splice junctions tell me?)

Thank you so much in advance!
