[ensembl-dev] gene centred info via slices

[Hardip Patel]

Dear all

I am trying to fetch gene centred information using following code. It takes a long time to extract information for all genes from human or mice at least.

I was wondering if the following code could be optimized to get information faster.

my $slice_adaptor = $registry->get_adaptor($spec, 'Core', 'slice');
  foreach my $slice (@{$slice_adaptor->fetch_all('toplevel')}){
    foreach my $gene (@{$slice->get_all_Genes}){
      foreach my $transcript (@{$gene->get_all_Transcripts}){
          foreach my $exon (@{$transcript->get_all_Exons}){
            ####get transcript, UTR, exon, and intron start and end in cDNA coordinates and genomic coordinates
        }
      }
    }
}
------

Regards
