I wrote this so far..
my @aminos=qw(A  R  N  D  C  Q  E  G  H  I  L  K  M  F  P  S  T  W  Y 
+ V  B  Z  X);
foreach my $key (sort keys %$A){
        print $key."  "x2;
        foreach my $key2 (sort keys %{$A->{$key}}){
            printf("%.2f  ", $A->{$key}->{$key2});
        }
    }
    print "\n"x10;
}
