[BioC] Need suggestions for constructing GOgraph

[Pradeep Battula]

Dear BioC users,

I am having the following data,

background.Datat: Entrez identifiers of all probes present on Illumina human HT12 v3. microarray
DEgenes.Data: Differentially expressed genes in a real study carried out on Illumina HT12 v3. microarray

Can anyone suggest, how to construct GOgraph for the available data....Thanks in advance.

Regards,
Pradee.
