Dear all,

More than a year ago, I ran affymetrix analysis with gcrma without problem.
I redo now the same command but apparently I have a problem with phenoData()
:

-------------------------------------
raw.data <- ReadAffy()
> eset <- gcrma(raw.data)
Adjusting for optical effect..........Done.
Computing affinities.Done.
Adjusting for non-specific binding..........Done.
Normalizing
Calculating Expression
Erreur dans phenoData(object) : pas de méthode directe ou héritée pour la
fonction 'phenoData' dans cet appel
-------------------------------------

I saw on the list that it could be due to changes in the Biobase package
which is now more "stringent" about the structure of the data ; I have 10
CEL files from hybridizations on hgu133plus2 arrays.

some more info :
