NAME

ArrayExpress::Datafile::Affymetrix::EXP - EXP data file parsing

SYNOPSIS

 use ArrayExpress::Datafile::Affymetrix::EXP;

 my $exp = ArrayExpress::Datafile::Affymetrix::EXP->new({
     input => 'data1.EXP',
 });
 $exp->parse();

This module implements parsing and export of data from Affymetrix EXP files.

Please see the ArrayExpress::Datafile::Affymetrix::Parser manpage for methods common to all the Affymetrix parser classes.

export($fh): This method takes a filehandle and prints out the EXP file in its original format. This method is not particularly useful and is really for testing purposes only.
get_chip_lot(): The lot number of the chip.
get_operator(): The person who performed the procedure.
get_protocol(): The name of the hybridization protocol used (e.g. EukGE-WS2v4).
get_station(): The station number.
get_module(): The module number.
get_hyb_date(): The date on which the hybridization was performed. This is returned in the same format as in the EXP file; no sanitization is performed.
get_pixel_size(): Pixel size (integer).
get_filter(): Filter (570nm).
get_scan_temp(): Scan temperature.
get_scan_date(): The date on which the scanning was performed. This is returned in the same format as in the EXP file; no sanitization is performed.
get_scanner_id(): Scanner ID.
get_num_scans(): Number of scans performed.
get_scanner_type(): Scanner type.
get_hyb_parameters(): A reference to an array of named hybridization parameters. Each parameter is coded as a separate hash with a single {name => value} pair. Typically this method is not very useful; you should probably be using the parameters or add_parameters methods instead.
