Problem with MethylAid ("Cannot get Manifest object for an 'Unknown' array") and Epicv2

Hey everyone,

I am working with data from the Epicv2 and I want to use several graphical interfaces to look at my data. I started by using ShinyMethyl and that worked without problem after I specify the array and manifest in the RGset.

RGset = minfi::read.metharray.exp(targets = samplesheet_1, verbose = TRUE, extended = TRUE)
#1.  Update the annotation package to hg38 coordinates for the Epicv2 from here: <>
annotation(RGset)["array"] = "IlluminaHumanMethylationEPICv2"
annotation(RGset)["annotation"] = "20a1.hg38"
shinyRGset_raw <- shinySummarize(object = RGset)

Problem is, when I tried to run MethylAid i get the following

> methAidData_raw <- MethylAid::summarize(samplesheet_1, file=RGset)
Start summarization ...
Summarize data in one go...
Error in .getManifestString(object@annotation) : 
Cannot get Manifest object for an 'Unknown' array

Now, I am a beginner in this, but I suppose that the problem is that since the input is the samplesheet, MethylAid doesn't have the array, manifest and annotation information. How can I specify it? Since both packages are minfi based, it should be possible I guess?
