Hi Adam, The Bimaps are not (in the strictest sense) deprecated. IOW we were not planning to make the ones that people have traditionally used go away anytime in the near future. So if you have old code that relies on these that code should all still be fine. But at the same time we are also not really adding any new ones and we are not exposing newer annotation resources by using the older bimap interface going forward. There are a lot of different reasons for this that I don't need to go into here. But regardless we have had a better way of doing these things for a couple years now that you are encouraged to take advantage of. So please look here for a little walk through of how we expect most users will interact with annotations today and in the future: http://www.bioconductor.org/help/workflows/annotation/annotation/ I hope this helps explain things better, Marc On 06/04/2014 10:07 AM, Cornwell, Adam wrote: > Thank you for the clarification.

These genes are present in current and previous versions of the Affymetrix probe -> gene mappings from NETAFFX. >> For example, transcript cluster 16966809 should correspond to gene symbol PDGFRA and Entrez ID 5156 (which is included in the NA34 annotation release for the platform) but any(mappedkeys(hugene20sttranscriptclusterSYMBOL) == "16966809") turns up FALSE. Picking a random transcript cluster, 16748695 (PDE6H), turns up TRUE and will return the symbol. I'm not sure if there are other genes missing as well, since I happened to stumble across this one. >> >> For now I can try to build an annotation database from the affy annotation.
