[BioC] How can I cluster GOTerms and assoiciated number of genes?

[Saurin D. Jani]

Hi,

How can I cluster GOTerms and assoiciated number of genes from my prob set ids?

something like:

e.g.

GOTERM                                 Number of Genes associated
----------------------------------------------------------------
steroid hormone receptor activity      132
steroid binding                        566
---------------------------------------------------------------
I have done something like below with my D E genes:

 Diff_MF <- makeGOGraph(myDiff_Genes,"MF","moe430a");

 Diff_MF_nodes = nodes(Diff_MF);

I have got terms below:
 MF_TERMS <- lookUp(Diff_MF_nodes,"GO","TERM");

 Diff_MF_nodes_2_affy = mget(Diff_MF_nodes,moe430aGO2ALLPROBES);


Information regarding making GO reports would be helpful,

Thank you so much,
Saurin Jani
