Function to processe large numbers of CEL files from different chip types
separately using the MAS5 normalization algorithm. To improve time performance,
the processing is parallelized with BiocParallel
to run on a computer cluster with a
scheduler (e.g. Torque).

The normalizeCel
function will write the results to sub-directories within the
data
directory. The sub-directories will be named after the chip types. Each one
of them will contain three files containing the MAS5 normalized intensities, the
corresponding P/M/A calls and the Wilcoxon rank p-values.
The function combineResults
will write the combined results to the same directories
as normalizeCel
.
Note: more detailed information should be added to this help file.
