Bio::Community::Role::Weighted - Role for objects that have a weight
package My::Package; use Moose; with 'Bio::Community::Role::Weighted'; # Use the weights() method as needed # ... 1;
This role provides the capability to add an arrayref of weights (strictly positive numbers) to objects of the class that consumes this role.

User feedback is an integral part of the evolution of this and other Bioperl modules. Please direct usage questions or support issues to the mailing list, firstname.lastname@example.org, rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

Usage : my $weights = $member->weights(); Function: Get or set some weights for this object. Weights represent how biased the sampling of this organism is. For example, when random shotgun sequencing microorganisms in the environment, the relative abundance of reads in the sequence library is not proportional to the relative abundance of the genomes because larger genomes contribute disproportionalely more reads than small genomes. In such a case, you could set the weight to the length of the genome. Do not attempt to change weights after a member has been added to a community! Note: Do not use a weight value of zero, except temporarily, and make sure to give a proper weight (>0) before adding a member to a community. Args : An arrayref of positive integers Returns : An arrayref of positive integers
