When it didn't work, you were using 
$string = "atccatccctttaat";
$triplets0 = $line=~ /(...)/;

Regexps return true/false in scalar context. Fixes: 
$string = "atccatccctttaat";
($triplets0) = $line=~ /(...)/;

or 
$string = "atccatccctttaat";
@triplets0 = $line=~ /(...)/;

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
