I have created two stand-alone functions for gene level annotation for
exon-arrays, which are available as part of oneChannelGUI package but
can be used without the oneChannelGUI interface.
The function standAloneBuildingLocalAnnotation creates a data frame with
gene-level annotation data for exon arrays (human, mouse or rat) using
the netaffx database informations.
The function standAloneAddingAnnotation attaches gene-level annotation
to a data frame.
You will find more info on the functionalities of these functions in the
vignette associated to oneChannelGUI release 1.12.4. I uploaded the
package on 28th December and I am expecting that it will be available on
the Bioconductor web in 24 hours.
P.S: let me know if these functions fulfill your needs, I will be happy
to improve them upon suggestion
