NAME

       Bio::PopGen::IO::csv -Extract individual allele data from a CSV parser

SYNOPSIS

       #Do not use directly, use through the Bio::PopGen::IO driver

         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 object will parse comma delimited format (CSV) or whatever delimiter you specify. It
       currently doesn't handle the more complex quote escaped CSV format.  There are 3
       initialization parameters, the delimiter (-field_delimiter) [default ','],
       (-allele_delimiter) [default ' '].    The third initialization parameter is a boolean
       -no_header which specifies if there is no header line to read in.  All lines starting with
       '#' will be skipped

       When no_header is not specific the data is assumed to be of the following form.  Having a
       header line this SAMPLE,MARKERNAME1,MARKERNAME2,...

       and each data line having the form (diploid data) SAMP1,101 102,100 90,a b or for haploid
       data SAMP1,101,100,a

   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:

APPENDIX

       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::csv->new();
        Function: Builds a new Bio::PopGen::IO::csv object
        Returns : an instance of Bio::PopGen::IO::csv
        Args    : [optional, these are the current defaults]
                  -field_delimiter => ','
                  -allele_delimiter=> '\s+'
                  -no_header       => 0,

   flag
        Title   : flag
        Usage   : $obj->flag($flagname,$newval)
        Function: Get/Set the flag value
        Returns : value of a flag (a boolean)
        Args    : A flag name, currently we expect
                  'no_header', 'field_delimiter', or 'allele_delimiter'
                  on set, new value (a boolean or undef, optional)

   next_individual
        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 $ind = $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 file format
        Returns : none
        Args    : L<Bio::PopGen::PopulationI> object(s)

   write_population
        Title   : write_population
        Usage   : $popgenio->write_population($pop);
        Function: Write a population out in the file format
        Returns : none
        Args    : L<Bio::PopGen::PopulationI> object(s)
        Note    : Many implementation will not implement this
