I have the following input data, showing only a few lines:

Pos      A      C      G      T
0      4      0     13      0     
1      5      0     12      0     
2     15      0      2      0      
3      0     17      0      0

I stored that data into an array of hashes called @matrix. For instance $matrix[0]{A}=4 and so on.

I want to sort each line from highest frequency to lowest frequency and store it in another array of arrays, but I also need to remember wich letter corresponds to each number

I thought it would be a good idea to store the nucleotide order at the end of the array, here is an example with the first lines that i would like to obtain:

First number is original position. I put it there because then i would like to sort the matrix by the top most score of each row.

[0 13 4 0 0 G A C T]
[1 12 5 0 0 G A C T]
[2 15 2 0 0 A G C T]
[3 17 0 0 0 C A G T]

I hope it's more clear now...
