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, bioperl-l@bioperl.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.

weights

 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
