View source: R/computeZoneIInfo.R

Computes the background and noise for a given zone of a single Affymetrix GeneChip

1	computeZoneIInfo(ZoneInfo, NumberBGCells)

`ZoneInfo`	vector of intensities in a given zone
`NumberBGCells`	number of background cells for the GeneChip

Calculates background and noise for a zone using the algorithms described in the Affymetrix Statistical Algorithms Description Document. This is an internal function that will generally not be accessed directly.

computeZoneIInfo returns a list containing the following components:

`background`	background value for the given zone
`noise`	noise value for the given zone
