I add: 
sub consensus {
   $rest='-';
   my %counts;
   $counts{$_}++ for @_;

   my ($consensus) = sort { $counts{$b} <=> $counts{$a} }
                     keys(%counts);

   return ( $counts{$consensus} / @_ >= 0.7
     ? $consensus
    : $rest
   );
}

but it prints whatever I have in the last line of the file, for example: 
 
-------------------AAAAA----------------------------BBBBBBBBBBBBBDDDDD

What am I missing?
