This function simply creates a directory tree in the current working directory or a user specified one. This directory tree helps organizing raw data files and at the same time gives R/Bioconductor the clue who to handle the provided data.

1	virtualArrayDirs(root_dir = getwd())

root_dir

If declared, this variable sets the top level directory where the whole tree will be placed.

The directory tree consists of a top level folder called "rawdata". Inside this folder there are directories for "Affymetrix", "Agilent" and "Illumina" respectively. Each folder holds sub-folders for the specific chips of the respective manufacturer. The user has to supply copies of the raw data into the appropriate directories for the package to work as expected.

This function returns no value. It just creates a directory tree.
