[BioC] GOstats question

[Rickman David]

 Hello,  
 
A naïve question (I am by no means an ace R user) concerning GOstats and splice variants:
 
why do you rely on locuslink to map GO terms when GOA that take into account splice variants as well via, for example, RefSeq?  Using the GOstats tool to study Affymetrix u133a data, I noticed that thhe hgu133aACCNUM mapping offers RefSeq mapping if I understand - knowing that you are limited to the genbank accession number attribution for a probe set offered by Affymetrix.
 
Thanks for any help/comments
 
 
David
