Hi everyone! I'm new to this mailing list as well as to programming and Perl in general. So there is a chance I might ask relatively stupid questions with very obvious answers... Please bear with me!
So, here it goes: I have a very long string with lots of Ns in it, like this: attttgctagccgagctaNNNNNNatggctaNNNNNNNatgcccctgaNNNNNNatg So, I want to get rid of the Ns and get ONE SINGLE newline for each group of Ns So far I've managed to do this: if ($joinedDNA =~ s/N+/\n/g) { $joinedDNA =~ s/\R//g; } But now I have everything joined together and can't tell where the Ns were before. I want output like so: attttgctagccgagcta atggcta atgcccctga atg Thanks for your help everybody, I really appreciate it! Parys
