[BioC] How to normalize one additional CEL file?

Dear List,

Suppose you normalize a training set in some way (RMA, etc.) to create a
predictor and then you want to apply this predictor on a single-CEL-file basis,
that is, your test set consists of only 1 new CEL file. (actually your test set
may consist of several new CEL files but they have to preprocessed and predicted

How can you preprocess / normalize one (test set) CEL file with the same
settings used to preprocess the training set? (NB! training and test set may not
be normalized together!) 
Are there some functions / packages that allow this, or would you suggest
another way of dealing with this?

Looking forward to hearing from you.

Best regards,
Wiktor Mazin
