Thanks for your quick reply. I modified the script as follows: 

my(@kmers);
for my$x (@AoA){
    for my$y (@$x){
        push @kmers, $y =~ /^(\w+)/; 
        print @kmers."\n";
        }
    }

but I am getting this output: 1 2 3 4 5 6 7 8 9 10 11 12 ... Is it printing just the scalar value? If so, why is that? I am often having this problem in other situations
