# BioPerl module for Bio::PopGen::PopulationI
#
# Please direct questions and support issues to <bioperl-l@bioperl.org>
#
# Cared for by Jason Stajich <jason@bioperl.org>
#
# Copyright Jason Stajich

# You may distribute this module under the same terms as perl itself
# POD documentation - main docs before the code
=head1 NAME
Bio::PopGen::PopulationI - Interface for Populations
=head1 SYNOPSIS
# Get Bio::PopGen::PopulationI object somehow, like
# from Bio::Population::Population
print "name is ", $population->name(), "\n";
print "source is ", $population->source(), "\n";
print "description is ", $population->description(), "\n";
print "For marker $markername:\n";
foreach my $genotype ( $population->get_Genotypes(-marker => $markername) ) {
print "Individual ", $genotype->individual_id, " genotype alleles are ",
join(',', $genotype->get_Alleles()), "\n";
}
# get a marker with allele frequencies calculated from the population
my $marker = $population->get_Marker($markername);
my %af = $marker->get_Allele_Frequencies;
foreach my $allele ( keys %af ) {
print "$allele $af{$allele}\n";
}
=head1 DESCRIPTION
This interface describes the basics of a population. One can use this
object to get the genotypes of specific individuals, only those
individuals which have a certain marker, or create a marker with
allele frequency information.
=head1 FEEDBACK
=head2 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.
bioperl-l@bioperl.org - General discussion
http://bioperl.org/wiki/Mailing_lists - About the mailing lists
=head2 Support
Please direct usage questions or support issues to the mailing list:
I<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.
=head2 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:
http://bugzilla.open-bio.org/
