What do you mean by "cross-post between mailing list" ? I usually mail to both Bioconductor and R to avoid the suggestion to email the 'correct' place. More so since i was not sure who would be better able to answer my question.

First order of business: please don't cross post between mailing list
-- it's generally considered bad etiquette.

What are the adjusted p-values for these genes?
