Re: More efficient way to lookup with 2 AoA's.

[Zaxo]

Use a hash with the gene names as keys. You can then put all the data in one structure,

my %gene = (
    gene_name_1 => { start=>'start_1', stop=>'stop_1', chr=>'chr_1'},
    # ...
);

You could add the score data there, too, unless it's more dynamic than that and is generated elsewhere.
