Masking repeats in ATAC-seq data

Wanted to get some opinions about masking repeats during differential peak calling for ATAC-seq or other open chromatin datasets, is this advised and if so what is a good strategy? Thanks.

I haven't seen a pipeline that does. ENCODE has a blacklist of regions which are typically excluded. I'd suggest looking over their pipeline:

I also have a more streamlined pipeline based on the ENCODE pipeline:

If you really want to exclude these regions, you could use dustmasker to identify intervals of interest / low complexity, then exclude associated tags corresponding to those genomic intervals.
