Hi Jim,

Not exactly. The problem is that using decideTests(..., method="nestedF")
with the whole set of genes (not filtered by any method), some of the
selected genes have an adjusted p-value quite large, corresponds to genes
with a very small M value.- Theses genes are in the list of differentially
exprssed genes selected with decideTests(..., method="nestedF").
For example, here I show you two of the genes for a particular contrast that
would be selected using decideTests(...,method="nestedF" )

I am a bit confused with this result?, Any clue?
