Subject: [BioC] problems with pd.genomewidesnp.6
To: Sebastian Thieme <thieme@mi.fu-berlin.de>
My suggestion is to download the annotation file provided by
Affymetrix and
check what it provides for the units mentioned below. If it differs
from
what is described in the package, I'll be happy to fix it. Otherwise,
you
may want to bring this to the attention of the Affymetrix team.
Right now, I'm not able to check this... If this is something you
could
check, we would be able to get to an explanation/solution soon. Note
that
the pd packages, regarding annotation, are simply a combination of the
CDF/PGF and associated annotation files.
