Malick,

A few months back, Chris Harbron posted a reply to a related question in which the RefPlus package was suggested for this purpose.   

Best,

Subject: [BioC] rma on new samples


hello,

I work for an invitro diagnostic company (www.biomerieux.com) and we are 
interested in classification of patients based on expression profile (we 
are working with affymetrix chips).

I built a classification model based on a training set and i have new 
samples and i want to make my new samples comparable with the training set 
in order to apply my built model.

We use RMA to compute expression measures.

If someone have a code to do this, it would be very greatful for me.

Ideally i want to extract rma parameters and apply them to my new samples, 
or if someone have a better idea.

Thanks in advance.

M.P
