NAME

       Bio::PopGen::IO - Input individual,marker,allele information

SYNOPSIS

         use Bio::PopGen::IO;
         my $io = Bio::PopGen::IO->new(-format => 'csv',
                                       -file   => 'data.csv');

         # Some IO might support reading in a population at a time

         my @population;
         while( my $ind = $io->next_individual ) {
             push @population, $ind;
         }

DESCRIPTION

       This is a generic interface to reading in population genetic data (of which there really
       isn't too many standard formats).  This implementation makes it easy to provide your own
       parser for the data.  You need to only implement one function next_individual.  You can
       also implement next_population if your data has explicit information about population
       memberhsip for the indidviduals.

FEEDBACK

   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 the web:

       The rest of the documentation details each of the object methods.  Internal methods are
       usually preceded with a _

   new
        Title   : new
        Usage   : my $obj = Bio::PopGen::IO->new();
        Function: Builds a new Bio::PopGen::IO object
        Returns : an instance of Bio::PopGen::IO
        Args    :

   format
        Title   : format
        Usage   : $format = $stream->format()

        Title   : next_individual
        Usage   : my $ind = $popgenio->next_individual;
        Function: Retrieve the next individual from a dataset
        Returns : L<Bio::PopGen::IndividualI> object
        Args    : none

   next_population
        Title   : next_population
        Usage   : my $pop = $popgenio->next_population;
        Function: Retrieve the next population from a dataset
        Returns : L<Bio::PopGen::PopulationI> object
        Args    : none
        Note    : Many implementation will not implement this

   write_individual
        Title   : write_individual
        Usage   : $popgenio->write_individual($ind);
        Function: Write an individual out in the implementation format
        Returns : none
        Args    : L<Bio::PopGen::PopulationI> object(s)

   write_population
        Title   : write_population
