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

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

new

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

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;
