I need to store all the numbers without the alphabets in my matrix. Also, the fact that there is unequal spacing between the numbers is making it really hard to convert to a matrix. This is a pssm matrix if that helps in anyway and I need to compute the shannon entropy from this matrix. 
The matrix is spaced to look correct but this is making it really hard for me to write correct code to store it as a 2D matrix. Any help will be greatly appreciated.

```
       A  R  N  D  C  Q  E  G  H  I  L  K  M  F  P  S  T  W  Y  V
1 T   -3 -4 -3 -4 -4 -3 -4 -4 -5 -3 -4 -3 -3 -5 -4 -1  8 -5 -4 -3
2 I   -4 -5 -6 -6 -4 -5 -6 -6 -6  7  0 -5  0 -2 -5 -5 -3 -5 -4  2
3 G   -1 -4 -2 -3 -4 -4 -4  7 -4 -6 -6 -3 -5 -5 -4  2 -2 -5 -5 -5
4 M   -3 -4 -5 -6 -4 -2 -5 -6 -4  2  1 -4 10 -3 -5 -4 -2 -4 -4  0
5 V    0 -4 -5 -5 -3 -4 -4 -5 -5  5  2 -4  0 -2 -4 -3 -2 -4 -3  4
6 V    4 -4 -4 -4  3 -3 -3 -2 -4  0 -2 -3 -2 -3 -3 -1 -1 -5 -3  4
7 I   -3 -4 -5 -5 -3 -4 -5 -6 -5  6  3 -4  2 -1 -5 -4 -3 -4 -3  2
8 H   -3 -4  0  7 -6 -2 -1  1  5 -6 -6 -3 -5 -5 -4 -2 -3 -6 -4 -5
9 K    2  0 -1 -1 -3  1  1 -1 -1 -3 -2  3 -2 -3 -1  1  0 -3 -2 -1

```

and so on for 141 rows.
