Mailing Lists¶

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated.

Support¶

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.

Reporting Bugs¶

Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their resolution. Bug reports can be submitted via email or the web:

set_Allele_Frequency¶

 Title   : set_Allele_Frequency
 Usage   : $population->set_Allele_Frequency('marker' => { 'allele1' => 0.1});
 Function: Sets an allele frequency for a Marker for this Population
           This allows the Population to not have individual individual
           genotypes but rather a set of overall allele frequencies
 Returns : Count of the number of markers
 Args    : -name      => (string) marker name
           -allele    => (string) allele name
           -frequency => (double) allele frequency - must be between 0 and 1
           OR
           -frequencies => { 'marker1' => { 'allele1' => 0.01,
                                            'allele2' => 0.99},
                             'marker2' => ...
                            }

add_Individual¶

 Title   : add_Individual
 Usage   : $population->add_Individual(@individuals);

 Args    : Array of Individuals

 Usage   : my @inds = $pop->get_Individuals();
 Function: Return the individuals, alternatively restrict by a criteria
 Returns : Array of Bio::PopGen::IndividualI objects
 Args    : none if want all the individuals OR,
           -unique_id => To get an individual with a specific id
           -marker    => To only get individuals which have a genotype specific
                        for a specific marker name

 Usage   : my @names = $pop->get_marker_names;
 Function: Get the names of the markers
 Returns : Array of strings
 Args    : [optional] boolean flag to ignore internal cache status

set_number_individuals¶

 Title   : set_number_individuals
    Usage   : $pop->set_number_individuals($num);

           0 to unset.
           Only use this if you know what you are doing,
           this is only relevant when you are just adding
           allele frequency data for a population and want to
           calculate something like theta
 Returns : none
 Args    : individual count, calling it with undef or 0
            will reset the value to return a number
