Computes the RawQ value of a single Affymetrix GeneChip
computeAffxRawQ(intensity, stdvs, pixels, probe.index, probe.zoneID, bgCells, NumberZones)
intensity |
vector of intensities for the GeneChip |
stdvs |
matrix of standard deviations for probe intensities from *.CEL file |
pixels |
matrix of number of pixels for probe intensities from *.CEL file |
probe.index |
vector of indices for each probe |
probe.zoneID |
vector of zone ID numbers for each probe |
bgCells |
number of background cells for the GeneChip |
NumberZones |
number of zones on the GeneChip |
Calculates RawQ 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.
the RawQ value for the given array
