computeZonenoise: Computes zone noise
Description
Computes the noise (average standard error) of the probe intensities
for a single Affymetrix GeneChip
Usage
computeZonenoise(index, intensity, stdv, npixels, bgCells)
Arguments
index
vector of indices for probes in the given zone
intensity
vector of intensities for the GeneChip
stdv
vector of standard deviations for the GeneChip
npixels
vector containing number of pixels for each probe of the GeneChip
bgCells
number of background cells on the GeneChip
Value
the noise of the probes for the given array
Details
Calculates the noise (average standard error) of the probes in a given zone, using
the algorithms described in the Affymetrix Statistical Algorithms Description Document,
for a single GeneChip. This is an internal function that will generally not be
accessed directly.
