In the previous post, due to my unclear description of the problem, the answer provided could only provide the number of repeated segments. However, I would like to know which segments in each bed file and the number of repetitions in the set bed file are missing, as well as which segments are zero repetitions compared to the set bed file. I really need your help, and I would greatly appreciate it if you could provide me with a solution
