Loops, thank you kindly for your solution.

For testing, the following code generated all, up to 4 in length, possible permutations with repetition of ACGT; the inclusion of incorrect characters can be added later by hand.

#!/usr/bin/perl # usage: ./ use strict; use warnings; use Math::Combinatorics; # my @n = qw(A C G T); my $o1 = Math::Combinatorics-> new(count=>1, data=>[@n], frequency=>[1, 1, 1, 1]); my $o2 = Math::Combinatorics-> new(count=>2, data=>[@n], frequency=>[2, 2, 2, 2]); my $o3 = Math::Combinatorics-> new(count=>3, data=>[@n], frequency=>[3, 3, 3, 3]); my $o4 = Math::Combinatorics-> new(count=>4, data=>[@n], frequency=>[4, 4, 4, 4]); my @b = (); # foreach my $o ($o1, $o2, $o3, $o4) { while(my @ox = $o->next_multiset) { my $p = Math::Combinatorics-> new(data=>\@ox, frequency=>[map{1} @ox]); while(my @oy = $p->next_string) { push@b, join('', @oy); } } } # foreach my $e (@b) { foreach my $f (@b) { print$e.','.$f."\n" } } # eof

test program:

#!/usr/bin/perl # usage: | use strict; use warnings; ## no valued added (petty) to Loops try 2 : Y #my $side = qr/(?:([ACGT])(?![^,]*\g{-1})){1,4}/; ## try 1 from Loops : N #my $side = qr/(?:([ACGT])(?![^,]*\1))+/; ## try 2 from Loops : Y my $side = qr/(?:([ACGT])(?![^,]*\g{-1}))+/; ## while (<>) { chomp; print "$_ ". (/^$side,$side$/ ? 'Y' : 'N') . $/; } # eof

and then:

$ ./ > y $ cat y | ./ > x $ less x

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
