NAME ^

Bio::PhyloNetwork::RandomFactory - Module to generate random Phylogenetic Networks

SYNOPSIS ^

 use strict;
 use warnings;

 use Bio::PhyloNetwork;
 use Bio::PhyloNetwork::RandomFactory;

 # Will generate at random all the 66 binary tree-child phylogenetic
 # networks with 3 leaves

 my $factory=Bio::PhyloNetwork::RandomFactory->new(-numleaves=>3,-norepeat=>1);

 my @nets;

 for (my $i=0; $i<66; $i++) {
   my $net=$factory->next_network();
   push @nets,$net;
   print "".(scalar @nets).": ".$net->eNewick()."\n";
 }

DESCRIPTION ^

Builds a random (binary tree-child) phylogenetic network each time next_network is called.

new

 Title   : new
 Usage   : my $factory = new Bio::PhyloNetwork::RandomFactory();
 Function: Creates a new Bio::PhyloNetwork::RandomFactory
 Returns : Bio::PhyloNetwork::RandomFactory
 Args    : -numleaves => integer
            OR
           -leaves => reference to an array (of leaves names)
           -numhybrids => integer [optional]
           -norepeat => boolean [optional]

Returns a Bio::PhyloNetwork::RandomFactory object. Such an object will create random binary tree-child phylogenetic networks each time next_network is called.

If the parameter -leaves=>\@leaves is given, then the set of leaves of these networks will be @leaves. If it is given the parameter -numleaves=>$numleaves, then the set of leaves will be "l1"..."l$numleaves".

If the parameter -numhybrids=>$numhybrids is given, then the generated networks will have exactly $numhybrids hybrid nodes. Note that, necessarily, $numhybrids < $numleaves. Otherwise, the number of hybrid nodes will be chosen at random for each call of next_network.

If the parameter -norepeat=>1 is given, then successive calls of next_network will give non-isomorphic networks.

next_network

 Title   : next_network
 Usage   : my $net=$factory->next_network()
 Function: returns a random network
 Returns : Bio::PhyloNetwork
 Args    : none
