I am just starting to do microarray analysis. I have been trying to normalize 4 chips (two dye-swap experiments done in biological replicates)
After doing backgroundCorrect(method="normexp") , one of the arrays has all of its $G values at NaN.
This does not happen when any other method is used.
Can someone tell me why this is, and if this can be fixed?
