Hello, I am using
bedtools jaccard to compare two vcf files, as:
bedtools jaccard -a ancestors.calls.norm.snp.vcf.gz -b GC078310.calls.norm.snp.vcf.gz intersection union-intersection jaccard n_intersections 1606899 1806667 0.889427 1536700
What I do not get is why n_intersections is equal to 1536700. Especially, the difference between intersection and n_intersections is not very clear to my mind.
Any help would be greatly appreciated.
Thanks a lot!
