[BioC] ChIPpeakAnno question--peak aggregation over bins from TSS

[Kamesh Narasimhan]

Hi Julie,

Thanks a lot for your reply. I am attaching the input files factor1.bed (TF signal file), hg17_ensembl.bed(annotation file), and the aggregated output (median of each bin). It would in principle to have options to plot mean/median/stdev of signals in each bin. 

An example of such a functionality is here http://tiling.mbb.yale.edu/frame1.html with example input/output files.

Best
kamesh

Kamesh,

Would you be interested in sending me a small test input and expected output for the new functionality? Thanks!

Best regards,

Julie
