It seems that the multiple test for the GO enrichment result is important. However, the TopGO didn't do that, so I decide to do that by myself. The delemma looks like this: fdr correction with `p.adjust()` in R need the complete GO enrichment result, whereas the `GenTable(,topNodes =N)` in TopGO only give out the top N result. So how can I do the "fdr" mutiple test correction to the GO enrichment results from "TopGO"?

Sincerely
Instead of specifying `topNodes` to some value N, you can get all available GO Terms using:

```r
allGO = usedGO(object = GOdata) 
# use it in GenTable as follows:
GenTable(GOdata, ... ,topNodes = length(allGO))
```

Then you can go about doing your p-value adjustment.
