from gene symbols to a BED file with TSS positions

[idogold]

Hi all

I have a list of gene symbols (in excel or txt file) and I would like to get a BED file containing all the TSS positions of that list.
How can I do that?

Thanks

Have you tried biomaRt package in R? Have found it very useful for such purposes.
I think you might be able to use their site by uploading your file and foramtiing accordingly as the BED file.
