in reply to Need help with complex tied data structure

Your code sample looks incomplete. You assign a ref to your tied hash to $data[$id] and then never do anything with it. Can you show a more complete example?

    $data[$gid] is a hash ref, so $data[$gid]->{$sample_id} is an element in that hash. To make it more explicit: 
        foreach $sample_id (@{$groups[$gid]}) {
        $data[$gid]->{$sample_id} = [];  # assign anon array ref to ti
+ed hash
        foreach $element_num ( 0 .. $element_count ) {
            $element = [];
            # ... do a bunch of stuff here ...
            $data[$gid]->{$sample_id}->[$element_num] = $element;
        }
    }

    Does that make more sense?

      Is that a typo in your original code then? You never put the tied hash into $data[$gid], you put it in $data[$id] instead.
