I am using STAR aligner to align an RNA-seq data with a human reference genome and I was analysing the log.final.out file. I am not sure what the following results mean:
Number of splices: GT/AG
Number of splices: GC/AG
Number of splices: AT/AC
Number of splices: Non-canonical :
I understand that the number of splices (total) gives the total number of splices in all the reads and number of splices (annotated) gives the those which are present in the annotation file.
What does canonical/non-canonical splicing mean?
