in reply to Fast Way to Split String in to Chunk of Equal Length

I am not sure it is fast but it works.
use Modern::Perl; use Data::Dump qw/dump/; my $seq = "CTTCGAATT"; # in this case length of 9 my @strings = $seq =~ /(.{3})/g ; say dump(@strings);
Output:
("CTT", "CGA", "ATT")

    I think your code is just a tad too example specific. I doubt that in his real data the string will always be 9 characters. But it will always be a multiple of 3.

    If it is always 9 characters, then your code is as good as an alternatives. update Wait a minute, did you just change your code? If not, I must have replied to the wrong node.

      Nope, did not change my code at all.
