The FilterMA node in SciCraft has the
following input arguments:
- MA: Raw microarray data in the form of a RG
limma object of normalised ratios (MA). That is objects
created by by the NormBetweenArrays and NormWithinArrays nodes.
- GeneStatus: String specifying the status label for the genes
that bear signal. Needed to remove control spots.
- SortGenes: Logical set to TRUE (default) if you would like to
sort the genes alphabetically by name. This is needed to make
duplicate genes come together in the list.
- RemoveControls: Logical set to TRUE (default) if
you would like to remove control spots from the gene list.
- MergeDuplicates: Logical set to TRUE (default) if you would like
to merge duplicate spots fro each gene in the array.
The output arguments from the node are:
- MAfiltered: MA object containing the filtered
ratios. That is, objects having the same form as objects produced by the
NormWithinArrays and NormBetweenArrays nodes.
