NAME

Bio::Matrix::PhylipDist - A Phylip Distance Matrix object

SYNOPSIS

use Bio::Tools::Phylo::Phylip::ProtDist;
my $dist = Bio::Tools::Phylo::Phylip::ProtDist->new(
  -file=>"protdist.out",
  -program=>"ProtDist");
#or
 my $dist = Bio::Tools::Phylo::Phylip::ProtDist->new(
  -fh=>"protdist.out",
  -program=>"ProtDist");


#get specific entries
my $distance_value = $dist->get_entry('ALPHA','BETA');
my @columns        = $dist->get_column('ALPHA');
my @rows           = $dist->get_row('BETA');
my @diagonal       = $dist->get_diagonal();

#print the matrix in phylip numerical format
print $dist->print_matrix;

DESCRIPTION

Simple object for holding Distance Matrices generated by the following Phylip programs:

1) dnadist 2) protdist 3) restdist

It currently handles parsing of the matrix without the data output option.

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 one of the Bioperl mailing lists. 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.
