Note, if there is no good evidence for differential
expression in the experiment, that it is quite possible for all
the adjusted
-values to be large, even for all of them to be
equal to one. It is quite possible for all the adjusted p-values
to be equal to one if the smallest
-value is no smaller than
'1/ngenes' where 'ngenes' is the number of genes with non-missing
-values. Note that
-values adjusted to control the false
discovery rate are often called
-values [6].
