In your example, I understand that 9 .. 38 is the "best hairpin," since it is the lowest start and highest end. Fair enough. But what if the ranges overlap? Say, you have 9 .. 38 and 8 .. 37?

Anyway, for populating your HOA, assuming the hsa_circ_... id is in $key, and the hairpin is delimited by $start and $end, you can use the following syntax: 

$HoA_sequences{$key} = [$start, $end];
