I want to normalize my affymetrix data which has more than 5000 .CEL files. since the system doesnot support these many files, i want to normalise my gene expression(.CEL) files using XPS
Now to normalise a file in xps we have to perform certain steps
1) Import additional CEL files into a DataTreeSet and update ROOT data file.
2) preprocess raw data
I am not able to understand on how create a root schema for my .CEL files
