Dear all,

I'm using the oligo microarray to find expression different genes. I decided
to use limma. This array have 3 spots for each gene.
But when I input the command
"fit<-lmFit(MA,design,ndups=3,correlation=cor$consensus)", It complains an
error on chol(V).
It works if I don't use ndups, but I need this. So, can you help me to solve
this problem?

best wishes

kevin
