In the last file (merge_circRNA_detail.anno) I cannot see a column to get the number of reads that have been aligned to each circRNA. There are other files (like splice.list) that do have this information, but the number of circRNAs is different, and not even a single coordinate match between files (I would say it is because the coordinates in the splice.list refer to the coordinates where the splice occur but not in the merge file).
I have forwarded the ticket to the author of CIRI-full, Yi.
