Dear Monks,
I am working with protein sequences and I have created a hash of array which holds the position and the respective amino acid, like:
1 M,
2 K,
3 L,

$HoA_sequence{$protein} = [$position, $aminoacid];

[download]
My problem is that, in some cases, there are missing amino acids, and I have a "jump" in the numbering, something like:
67 A,
68 S,
77 W,
78 P,
79 I

[download]

So, can you help me how I can, my iterating in my Hash of array, add "-" in the missing positions? So that the final HoA would be this:
67 A,
68 S,
69 -,
70 -,
71 -,
72 -,
73 -,
74 -, 
75 -,
76 -,
77 W,
78 P,
79 I
