Do you want miRNA target *sites* or target genes? Also, what do you
by 'all'? To my knowledge, miRNA->mRNA mapping is based on sequence
similarity, which implies a cutoff that can be varied (so 'all' is a
Anyway, you could use the microCosm files that you can download here:
The files contain the Ensembl transcript ID, as well as the chr, start
and end. So a simple tapply() (or by()) will give you the by-
miRNAs, and you can go from there.
