identification of overlapped, proximal and distal gene for peak regions

Question

[Omics data mining]

Hello Everyone I am working on Chip seq peak regions. I am interested to identify if there are any overlapped or proximal genes and distal genes for each peak regions. Previously I used bedops for the identification of first closest match. Is it possible to define desired overlap criteria while annotating "peak regions" against gff file with bedops method ? I will appreciate all the suggestions !!

Thanks in advance
