Dear R Users,
In the expresso function, which combination of these methods for data pre-processing (when using affymetrix oligo arrays) is the best:

bgcorrect.metod = rma rma2 mas

normalize.method = qspline quantiles loess

pmcorrect.method = pmonly subtractmm mas

summary.method = liwong avgdiff medianpolish mas

There are many options within each method. I would appreciate a hint on the best combination. 
Thank you very much in advance.
Roger
