Differentially accessible and known enhancer overlap

Question

[p4alindromic]

Hi everyone,

I want to see if my differentially accessible peaks that I obtained from ATAC-seq comparisons overlap with known enhancers. I read people using bedtools intersect to see if there is overlap but there is usually no mention of the minimum length/percentage of overlap required. What would make sense to determine whether a peak region truly overlaps an identified enhancer?

Thanks!
