NAME

Bio::PopGen::Utilities - Utilities for working with PopGen data and objects

CONTENTS

SYNOPSIS



  use Bio::PopGen::Utilities;
  use Bio::AlignIO;

  my $in = Bio::AlignIO->new(-file   => t/data/t7.aln,
                            -format => clustalw);
  my $aln = $in->next_aln;
  # get a population, each sequence is an individual and
  # for the default case, every site which is not monomorphic
  # is a marker.  Each individual will have a genotype for the
  # site which will be the specific base in the alignment at that
  # site
  my $pop = Bio::PopGen::Utilities->aln_to_population(-alignment => $aln);

  # get the synonymous sites from the alignemt only as the genotypes
  # for the population
  my $synpop = Bio::PopGen::Utilities->aln_to_population(-site_model => cod,
                                                         -alignment  => $aln);



DESCRIPTION

This object provides some convience function to turn sequence alignments into usable objects for the Population genetics modules (Bio::PopGen).

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:

APPENDIX

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

    aln_to_population



 Title   : aln_to_population
 Usage   : my $pop = Bio::PopGen::Utilities->aln_to_population($aln);
 Function: Turn and alignment into a set of L<Bio::PopGen::Individual>
           objects grouped in a L<Bio::PopGen::Population> object

           Sites are treated as Markers in the Bioperl PopGen object
           model in the sense that a site is a unique location for which
           an individual will have a genotype (a set of alleles).
           In this implementation we are assuming that each individual
           has a single entry in the alignment file.

           Specify a site model as one of those listed
           all -- every base in the alignment is considered a site
           cod -- codons

           The option -site_model
                for All sites          : all
                    Codon sites        : cod or codon

          To see all sites, including those which are fixed in the population
          add -include_monomorphic => 1
          to the arguments
 Returns :
 Args    : -include_monomorphic => 1   to specify all sites,
                                       even those which are monomorphic
                                       in the population
                                  (useful for HKA test mostly)
                            [default is false]
           -phase          => specify a phase for the data, this is only
                              used if the site_mode is codon
                            [default is 0]
           -site_model     => one-of all, codon
                             to specify a site model for the data extraction
                             from the alignment
                            [default is all]
           -alignment      => provide a L<Bio::SimpleAlign> object [required]
