Please keep all replies on the list: somebody else may also wish to help 
(and they will also pick up mistakes I make ;-)

So, you are using -1 for true and 1 for false? Can there be multiple 
amino acids on each line?

Would this be a possible input:

1lghB AHG i 87.3 Q Q   -23.45

If so, would this be the required output?

-1 1:1 2:0 3:0 4:0 5:0 6:0 7:1 8:1 9:0 10:0 ... 19:0 20:0

There is no point trying to write more code until we understand the 
requirements properly.
