Hi Wendy, Can you please be a bit more specific about what you want to do? Some code and the output from sessionInfo() would help a lot. Also you might want to look at our posting guide here: http://www.bioconductor.org/help/mailing-list/posting-guide/ I am also curious about why you want to use a GO slim collection instead of a regular annotation?
