Is it common for ATAC-peaks to be located in Repeat Masker annotated regions?

Question

[a.rex]

I have ATAC-reads that map to make peaks in repeatMasker + repeat modeller annotated regions? Is this common? Is this an artefact of mapping or perhaps regulatory elements that are transposon derived?

Like 10 reads or 1e+08, and what is the total read count and total peak number and peaks in these problematic regions ? You are lacking details.
