Hello,
I was wondering where the mapping from affy probeset Ids to genes
(EntrezGene) is coming from (package mouse4302.db).
mouse4302.db::mouse4302_dbInfo lists all data sources (URLs) However,
what's the "original" link between an affy probeset and an EnterzGene
Id,
is it Netaffx? My problem is that I've an "interesting" probeset that
is
annotated with an EntrezGene in Netaffx but the mouse4302SYMBOL map
contains NA for this probeset Id.
I'd be happy if someone could point me to some documentation how this
annotation/mapping is derived or let me know what I'm doing wrong ...?
thanks a lot for your help,
arne
