convertCel {affxparser}R Documentation

Converts a CEL into the same CEL but with another format

Description

Converts a CEL into the same CEL but with another format. Currently only CEL files in version 4 (binary/XDA) can be written. However, any input format is recognized.

Usage

convertCel(filename, outFilename, readMap=NULL, writeMap=NULL, version="4", ..., .validate=FALSE, verbose=FALSE)

Arguments

filename The pathname of the original CEL file.
outFilename The pathname of the destination CEL file. If the same as the source file, an exception is thrown.
readMap An optional read map for the input CEL file.
writeMap An optional write map for the output CEL file.
version The version of the output file format.
... Not used.
.validate If TRUE, a consistency test between the generated and the original CDF is performed. Note that the memory overhead for this can be quite large, because two complete CDF structures are kept in memory at the same time.
verbose If TRUE, extra details are written while processing.

Value

Returns (invisibly) TRUE if a new CEL was generated, otherwise FALSE.

Benchmarking of ASCII and binary CELs

Binary CELs are much faster to read than ASCII CELs. Here are some example for reading complete CELs (the differnce is even larger when reading CELs in subsets):
