Hi everybody,

I'm performing some gene profiles from my ChiP seq experiment. To do that, I've used homer or ChipSeeker for the annotation. I am deeply interested in get (not only) the Transcription Start Sites (TSS) and Transcription End Site (TES) for each gene, to perform downstream analysis. Does any anybody can suggest any tool or package for get this data?

Thank you!

If you got human or mouse data, you could download the FANTOM5 (http://fantom.gsc.riken.jp/data/) annotated promoters and use an intersecting tool to annotate your start sites with that.

I have the TSS what I need is the TTS.could be ok if I do : TSS+geneLength = TTS?

Couldn't you just use the gene names as input into the UCSC browser and make a BED file of them? That would include the TSS and TES.

Also a list of more than 20000000 genes? I can't upload one by one.. can I do all at the same time?

What kind of genome are you working with where you have 20 million genes?

It is an example, because If I have 2000 genes, I can't look for the TTS manualy in USCS, please, could you explain your aproach better?

Thank

Essentially what I am suggesting is you take the gene name for all 2000 of your genes. You "paste" the list into UCSC table browser for your genome, and then you download the file in .bed format. That will give you a your TSS in Column 2 and your TES in Column 3.
