ChIPpeakAnno to find peaks nearest to miRNA
... 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 ...

Comment: C: A basic question about retrieve the absolute genome position from the output of
... Steve, As the motif I am interested is [AAGTTTAA]. Then I got a result on the negative strand as chr3:49450073-49450080, [GGTGAGGC], which is reversely complementary to [AAGCCTCA]. Should I compare the reversely complementary hit to the motif? If a hit is on a positive strand, then to compare the ...
