Hello all

I have some significant Illumina v1 gene expression probes (and their 
probe 'universe') I want to  run GO enrichment analysis on.

I assume that:
(i)  I need illumnaHumanv1.db for the GO2PROBE mappings
(ii) I need to to create a GO2gene object for input into topGO as:
new("topGOdata", ontology="BP", allGenes=my.probe.list, 
annot=annFUN.GO2genes, GO2gene=my.GO2gene)

I'm just not joining the mental dots dots between (i) and (ii). Or am I 
completely missing the point? Any quick/simple guidance to get from my 
probes to a topGOdata object would be very, very welcome - thanks!
