Hi Rae,

It occurs to me that you might be referring to////
<http://www.chlamy.org/> Chlamydomonas, in which case you will be using
an unsupported organism.  We have some support for those however if you
look at the vignette in the file "GOstatsForUnsupportedOrganisms.pdf" in
the GOstats package:

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

You will have to find or generate a mapping between the genes for your
organism and the GO terms though.  You might want to check the blast2GO
project for that.
