The NormWithinArrays node in SciCraft has the
following input arguments:
- RG: A RG object
containing the expression ratios for a series of arrays. If the
object has not previously been background corrected, the
``subtract'' background correction method will be applied prior to
the normalisation.
- method: Text box specifying which normalisation method that is
going to be applied. Has the following five options:
- none (default)
- median
- loess
- printtiploess
- robustspline
The output arguments from the node are:
- MA: limma object containing the normalised
ratios. Contains the following elements:
Where
and
donate the red and green
foreground intensities.
- weights: Matrix containing the weights given to the
genes.
- genes: R object containing the information
about the genes.
- targets: Matrix containing the files the data stems
from.
- printer: R object containing the printer information.
