Dear Bioconductor List,

	In an earlier posting, Gordon Smyth recommended
a tentative cutoff of B>=0 for Limma output.
Is it okay to publish Venn diagrams based on this
cutoff or should the cutoff be validated by spot-checking with PCR?
Is it okay to publish pathway overrepresentation
analyses with this cutoff, or is PCR validation of the cutoff
advised?

Thanks and best wishes,
Rich
