Hi,

I am trying to run the function "preprocessIllumina" from the minfi package on my RGset data. I have been able to import the targets and the RGset. I have also been using the appropriate manifest file and annotation. The code that I am trying to execute is as follows:

preprocessIllumina(RGset, bg.correct = TRUE, normalize = "controls", reference = 1)

Here's the error that is produced:

 Error in h(simpleError(msg, call)) : 
  error in evaluating the argument 'x' in selecting a method for function 'match': object 'CG.controls' not found
In addition: Warning message:
useNames = NA is deprecated. Instead, specify either useNames = TRUE or useNames = TRUE.

Any suggestions on how to fix this?

Best regards

You need to provide the output of sessionInfo() and from traceback() right after you get the error.

What array is this? One of those Horvath mammalian arrays, or an EPIC?

Could you show the output of RGset ? What I suspect is that you have an EPICv2 array and it seems minfi does not support this type of array for the moment

The idat files are generated from the HorvathMammalMethylChip40. I provide the correct manifest file in subsequent steps during the analysis.

Sure it does. But you need to get the manifest from Zuguang Gu https://jokergoo.github.io/IlluminaHumanMethylationEPICv2manifest/

The Horvath arrays may not have control probes. You can check. Here's what is on an EPICV2

And if you don't see NORM_A - NORM_T in that list, then that's your problem.

It appears that you are getting that from the manifest object. What do you get when you do

z <- getProbeInfo(RGset, "Control")

You might need to do

annotation(RGset) <- c(array = "HorvathMammalMethylChip40manifest", annotation = "test.unknown")

Yes, I do this in the subsequent steps

Oh wait. The code for normalize.illumina.control has this

if (.is450k(rgSet) || .isEPIC(rgSet) || .isAllergy(rgSet)) {
        AT.controls <- getControlAddress(object = rgSet, controlType = c("NORM_A", 
            "NORM_T"))
        CG.controls <- getControlAddress(object = rgSet, controlType = c("NORM_C", 
            "NORM_G"))
    }
    if (.is27k(rgSet)) {
        AT.controls <- getControlAddress(object = rgSet, controlType = "Normalization-Red")
        CG.controls <- getControlAddress(object = rgSet, controlType = "Normalization-Green")
    }
    Green.avg <- colMeans2(Green, rows = match(CG.controls, rownames(Green)))
    Red.avg <- colMeans2(Red, rows = match(AT.controls, rownames(Red)))

And your array is going to fail all those .isXXX tests, which are going to do tests like

annotation(object)["array"] == "IlluminaHumanMethylationEPIC"

So maybe you need to first change the array to e.g., IlluminaHumanMethylationEPIC and change back later. No guarantee that will work though. You might contact the Horvath group or look through their GitHub to see if there is a workaround that they recommend.
