[BioC] about packages GO, Gostats,...

[Martin Olivier]

Dear all,

I have some difficulties to use packages such that GOstats or GO...
So, I have two questions...(I tried to  find the solutions in the 
mailing list but I don't find them...)...Maybe, there are trivial 
solutions...


First, how I can find all the different GO category associated with a
locus identifier ?

Second, is it possible to reverse the previous question, that is to
find all the locus associated to a GO category ?

Thanks a lot for your help...

Best regards,
Olivier.
