[BioC] Gene Ontology analysis for non-affy data

[Marc Carlson]

Hi Yupu,

You should read the tutorial vignette for the GOstats package.  I think
it will probably show you what you need to know:

You can find the GOstats package here:

http://www.bioconductor.org/packages/release/bioc/html/GOstats.html

And the tutorial here:
