Annotation of ATAC-seq peak - distal intergenic regions as enhancers

Question

[Pei]

Hi!

I just read a paper and in Fig. 1, the authors provided a "typical peak annotation pie chart shows that more than half of the peaks fall into enhancer regions (distal intergenic and intronic regions),..."

So, I wish to know if it is a common sense that in ATAC-seq data, distal intergenic and intronic regions could be considered as enhancers if they are associated with peaks?

Thanks in advance.
