[Bioperl-l] Getting genomic coordinates for a list of genes

Today I discovered that the coupling of the two subs that Mark posted
doesn't get the right results. I think this is because one gets the
coordinates with RefSeq build 36.3, the other with build 37.
I found that coupling the first sub, genome_coords, with the
Bio::EnsEMBL::Registry fetch by region API is a lot better, and it actually
generates sequences that contain the genes.
Thanks a lot to Mark!!
