Hi! i want to identify target genes for disease associated SNPs. i need to check SNPs locations within enhancer regions for this i need all enhancer regions with all histone marks ,so i can see with visualization tools (e.g IGV) where is peak for this histone which is representative for the enhancers. in other words i need histone modification of different layers and then i can annotate like this is enhancer region.

Since iam new in this field , so iam confused which data files and in which file format should i use and how to analyze them in order to know enhancers? please help me Thank you very much
