NAME

Bio::MAGETAB::SDRF - MAGE-TAB SDRF class

SYNOPSIS

 use Bio::MAGETAB::SDRF;

DESCRIPTION

This class is used to describe the SDRFs used in a given investigation. See the BaseClass class for superclass methods.

ATTRIBUTES

uri (required): The URI specifying the location of the SDRF (data type: Uri).
sdrfRows (optional): A list of SDRFRow objects which describe the row structure of the SDRF. In so doing, these SDRFRows link the SDRF nodes to their respective investigation, factor value and channel (data type: Bio::MAGETAB::SDRFRow).

METHODS

add_nodes: Passed an arrayref of Node objects, this method automatically sorts them into SDRFRow objects, which it then stores. Currently this method is not intelligent enough to sort Nodes into pre-existing SDRFRows, so it is recommended to use this method only once you have created all your Nodes (this may be fixed in a subsequent release).

Each attribute has accessor (get_*) and mutator (set_*) methods, and also predicate (has_*) and clearer (clear_*) methods where the attribute is optional. Where an attribute represents a one-to-many relationship the mutator accepts an arrayref and the accessor returns an array.
