Hi, Jianrong, Do you think I can use ChIPpeakAnno to get both sided genes for a peak region? If so, how do you suggest, using both the TSS and TTS, or use both the 5UTR and 3UTR? Thanks a lot, Holly

xyang2,

There is a new function called annoPeaks() in ChIPpeakAnno now.

annoPeaks (peaks, annoData, 
          bindingType=c("nearestBiDirectionalPromoters",
                        "startSite", "endSite", "fullRange"), 
          bindingRegion=c(-5000, 5000), 
          ignore.peak.strand=TRUE,
          select=c("all", "bestOne"),
          ...)

you can get the nearest upstream genes, and nearest downstream genes, then merge them.
