Hello, Wei.

I'm not sure if you meant to post this question twice in two days, but that
is generally not the best way to go about getting an answer.  I would
suggest that you read the posting guide (the link to mailing list
information is at the bottom of every email that comes from this list) and
follow it.  In addition, Saroj and Thomas have already offered some useful
suggestions.  If you have missed those for some reason, the list archives
are available (again, the link is at the bottom of all emails from the
list).

As to your question, there are a dozen or more websites available for
looking at GO enrichment or gene annotation.  I would suggest you look into
those (and a google search will be the place to start, here), as they are
meant to be quick and easy to use.  Of course, if you would rather use
R/Bioconductor and you have further questions about the suggestions that
others have already offered, please be more specific about what you have
tried, what errors you might have received, the code that you used, and the
sessionInfo() from your R session.
