NAME

Bio::Expression::MicroarrayIO::dchipxls - Work with dChip analysis of an Affymetrix array.

SYNOPSIS

  $stream  = Bio::Expression::MicroarrayIO->new(
		'-file'     => "my.xls",
		'-format'   => "dchipxls",
											   );

DESCRIPTION

Bio::Expression::MicroarrayIO::dchipxls parses dChip XLS files. These are a processed (normalized) form of Affymetrix CEL files using the algorithm described in: Li C, Hung Wong W. Model-based analysis of oligonucleotide arrays: model validation, design issues and standard error application. Genome Biol. 2001;2(8)

APPENDIX

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

new

 Title   : new
 Usage   : Bio::Expression::MicroarrayIO::affymetrix->new(
											  -file     => 'path/to/filename',
											  -template => 'path/to/template')
 Comments: You should probably not be instantiating this module directly.
           Use MicroarrayIO instead.
 Args    : -file     => filename
           -format   => format
           -template => template

_initialize

 Title   : new
 Usage   : $affy->_initialize(
							  -file     => 'path/to/filename',
							  -template => 'path/to/template'
							 );
 Function: Loads up a template module that will be used to
           by next_array();
 Returns : nothing.
 Args    : -file     => filename
           -format   => format
           -template => template

datafile

Title   : datafile
Usage   : $affy->datafile('path/to/datafile');
          $affy->datafile();
Function: get/set the the location of a data file
Returns : path to a data file
Args    : optional path to a data file

next_array

Title   : next_array
Usage   : $affy->next_array();
Function: reads an Affymetrix data record from $affy->datafile
Returns : a  Bio::Expression::Microarray::Affymetrix::Template object
          that has been filled with probe values.
Args    :

write_array

Title   : write_array
Usage   : $affy->write_array($array);
Function: write an Affymetrix data record using $array
Returns : nothing.  prints a lot of text.
