createUniqueCdf.AffymetrixCdfFile {aroma.affymetrix}R Documentation

Creates a unique-cell version of the CDF

Description

In some cases, single probes map to multiple genome locations. In cases where you may later want to store a probe estimate (e.g. a probe effect or a residual), you will not be able to store more than one per cell. The unique CDF facilitates this by making the cell indices unique (essentially copying the multimapping probes).

Usage

## S3 method for class 'AffymetrixCdfFile':
createUniqueCdf(this, chipType=getChipType(this), tags="unique", sep=",", path=NULL, units=NULL, ..., ram=NULL, verbose=TRUE)

Arguments

chipType The chip type of the new CDF.
tags Tags added to the chip type of the new CDF.
sep A string separating the chip type and the tags string.
path The path where to store the new CDF file.
... Additional arguments passed to writeCdf.
ram A double saying if more or less units should be converted per chunk. A smaller value uses less memory.
verbose A logical or Verbose.

Value

Returns the unique CDF as an AffymetrixCdfFile object.
