Thanks for the feedback and your kind word!

Please see my response below. BTW, could you please cc the Bioconductor list
bioconductor at r-project.org next time so that others could contribute or/and
benefit? Thanks!

Best regards,

I usually use maxP = 0.05, multiAdj=TRUE, minGOterm = 5, multiAdjMethod="BH"

You could try to set maxP = 0.1 and see if there are some terms with
adjusted p-values on the boarder line.

Very good question. Yes, the gene list is filtered to contain a unique gene
list prior to GO anlayis.
