Dear List,
I am using siggenes1.2.17 on R 2.1.1. I have an object of class "sumSAM". I want to obtain a list of differentially expressed genes, so I try the following:
sum.sam.out<-summary(sam.out,3.0,ll=FALSE)
When I try to get the list of significant genes
sum.sam.out$row.sig.genes
I get a NULL. 
I checked the slotNames(sum.sam.out)
"row.sig.genes" "mat.fdr" "mat.sig" "list.args"
but they are all NULL.  
Thanks in advance.
