EPIC annotation

[trandoanduyhai]

Dear Victor,
I ran EPIC methylation array and trying to examine probes that associate with promoter regions. I notice that the latest b4 annotation contains information (promoter associated, gene associated, etc.) for only less than 30% of 865k probes. Thus, I am interested in your proposed method.
Do you have a script to intersect probe coordinates and UCSC annotations for cpg islands?
Thank you in advance!
