Hi corona,

Thanks for the solution.

I think it considering only the first two columns, but the last two columns should also be considered. This is the output from your solution

Code:
7488	7389	chr1.fa	chr1.fa	3
3546	9887	chr5.fa	chr9.fa	2
7387	7898	chrX.fa	chr3.fa	2
7488	7389	chr21.fa	chr3.fa	3
7488	7389	chr1.fa	chr1.fa	3
3546	9887	chr9.fa	chr5.fa	2
7898	7387	chrX.fa	chr3.fa	2
