Hello everyone,

Using ChAMP to Analyse my EPIC Array data I am struggeling with functional normalization.

I load my data using the minfi method to ensure that rgset and mset are present.

myLoad<- champ.load(directory = test.dir, arraytype = "EPIC", method = "minfi", force = TRUE)

For some datasets functional normalization works well but in two datasets I got the following error:

myNorm<- champ.norm(arraytype = "EPIC", method="FunctionalNormalization")

SWAN, BMIQ and PBC normalization work quite well.

May anyone has a suggestion how to fix that problem? I would highly appreciate that.

Many thanks in advance and best wishes

Hi Laura, 

I met the same problem while using FunctionalNormalization, but SWAN, BMIQ and PBC can work fine. Have your problem solved?

Thank you so much.

Yu
