[BioC] Gene Ontology analysis for non-affy data

[Adrian Alexa]

Hi Yupu,

you can use topGO package with any list of genes as long as you have
the gene-to-GO mapping. You can use either Bioconductor annotation
packages or pain text files which list the gene-to-GO mapping. Look at
the manual page for "annFun" function in topGO for more information.

Best,
Adrian
