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

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.

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)
