Hi,

take a look at the Graph module:

use warnings; use strict; use Data::Dumper; use Graph; my $g = Graph->new(directed => 1); $g->add_vertex("Contig$_") for (1..11); while (my $line = <DATA>){ my @nodes = split( /\s+/,$line ); $g->add_edge( @nodes ); } print Dumper $g->weakly_connected_components; __DATA__ Contig1 Contig2 Contig1 Contig3 Contig2 Contig1 Contig2 Contig3 Contig3 Contig1 Contig3 Contig2 Contig3 Contig4 Contig4 Contig3 Contig4 Contig5 Contig6 Contig7 Contig7 Contig6 Contig8 Contig9 Contig9 Contig10 Contig10 Contig8 Contig10 Contig11 Contig11 Contig10
Cheers, Christoph

Title:
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 or How to display code and escape characters are good places to start.
