Hello everybody,
I was trying to normalize my data using expresso and found this warning
message. Can please explain what went wrong?
Data <- ReadAffy()
eset <- expresso(Data,bgcorrect.method="mas",
normalize.method="quantiles",
pmcorrect.method="mas",
summary.method="medianpolish")
The wornging I got :"medpolish() not converged in 10 iterations in medpolish
(log2(x),..."
Thanks.
