GcRmaBackgroundCorrection: The GcRmaBackgroundCorrection class

Description

Package: aroma.affymetrix Class GcRmaBackgroundCorrection Object ~~| ~~+--AromaTransform ~~~~~~~| ~~~~~~~+--Transform ~~~~~~~~~~~~| ~~~~~~~~~~~~+--ProbeLevelTransform ~~~~~~~~~~~~~~~~~| ~~~~~~~~~~~~~~~~~+--BackgroundCorrection ~~~~~~~~~~~~~~~~~~~~~~| ~~~~~~~~~~~~~~~~~~~~~~+--GcRmaBackgroundCorrection Directly known subclasses: public static class GcRmaBackgroundCorrection extends BackgroundCorrection This class represents the GCRMA background adjustment function.

Usage

GcRmaBackgroundCorrection(..., indicesNegativeControl=NULL, affinities=NULL, type=c("fullmodel", "affinities"), opticalAdjust=TRUE, gsbAdjust=TRUE, gsbParameters=NULL)

Arguments

...
Arguments passed to the constructor of ProbeLevelTransform.
indicesNegativeControl
Locations of any negative control probes (e.g., the anti-genomic controls on the human exon array). If NULL and type == "affinities", then all non-PM probes are used as th
affinities
A numeric vector of probe affinities, usually as calculated by computeAffinities() of the
type
Type (flavor) of background correction, which can be either "fullmodel" (uses MMs; requires that the chip type has PM/MM pairs) or "affinities" (uses probe sequence only).
gsbAdjust
If TRUE, adjustment for specific binding is done, otherwise not.
opticalAdjust
If TRUE, correction for optical effect is done first, utilizing OpticalBackgroundCorrection.
gsbParameters
Additional argument passed to the internal bgAdjustGcrma() method.
