Dear mailing list,
I know this was on the list couple of times, and I think I read it
all, but
actually I still don't get it right. So here is my problem:
I want to be able to work with Mouse Exon 1.0 ST Arrays (NOT Mouse
Gene 1.0
ST) in a similar fashion to eg. HG-U133 arrays.
That means, I want to finally have it accessible as an ExpressionSet
object
with a right Bioconductor annotation assigned. This should include
GENE
SYMBOLS, RefSeq IDs and ENTREZ IDs.
I can import it as a AffyBatch and generate an ExpressionSet with the
help
of the Xmap/exonmap supplied CDF, but there is no annotation attached
to it.
OR
I can import the CEL files with the "oligo" package as a Exon Array
object
and generate an ExpressionSet from it.
However in that case it still have no annotation.
Surprisingly on the Bioconductor website there are all packages needed
to
deal with Mouse Gene 1.0 ST arrays but the informtion to work with
Mouse
Exon 1.0 ST arrays seems missing!
What am I doing wrong here? Has someone else had such problems?
Thanks in advance for your effort,
Andreas
