qc.read.file {simpleaffy}R Documentation

Read a file defining the QC parameters for a specified array and set up the QC Environment

Description

Affymetrix define a series of QC parameters for their arrays. Many of these rely on specific probeset that differ between arrays and are used to calculate things like 3'/5' ratios. See qc.affy for more details. This is usually done by a call to setQCEnvironment; the function described here is the one that does the actual loading of the configuration file. See the package vignette for details of the config file's syntax.

Usage

  qc.read.file(fn)

Arguments

fn full path and name of the file to load
