affyread

Read microarray data from an Affymetrix GeneChip file

Syntax

AFFYData = affyread(File)
AFFYData = affyread(File, LibraryDir)

`File`	Enter a filename, or a path and filename supported by your computer. Supported file formats are `DAT`, `EXP`, `CEL`, `CHP` and, `CDF`. If the file cannot be located on the web, it needs to be stored locally.
`LibraryDir`	Enter the path and directory where the library file (`CDF`) is stored.

AFFYData = affyread(File) reads an Affymetrix data file (File) and creates a MATLAB structure (AFFYDdata).

AFFYData = affyread(File, LibraryDir) specifies the directory where the library files (CDF) are stored.

Note: The function affyread only works on PC supported platforms.
