[Genome] Converting coordinates on a mRNA to coordinates on the genome

[Russell, Archie]

Hi,

I have some coordinates relative to mRNAs (transcript features) that I'd
like to turn into coordinates on the genome.   I can blat the mRNA to
the genome, but doing the math for the translation is a little tricky,
in particular on the reverse strand.   Do you have any code or
recommendations for how to do this?

Thanks,
Archie
