[BioC] Getting annotation into GOstat

[Naomi Altman]

Hi,
I have used GOstat with annotations already formated for 
Bioconductor.  Now my colleague sent me a file with the annotations - e.g.

Gene Name,GO ID,GO Description

GRMZM5G802875,,
GRMZM2G116557,6355,"regulation of transcription, DNA-dependent"
GRMZM2G116557,5634,nucleus

What functions do I need to use to get this information into a 
database so that I can run GOstat?

Thanks,
Naomi
