Hi, after performing this code

sigCpGs <- DMPs$Name[DMPs$adj.P.Val<0.05]
length(sigCpGs)
[1] 311082
all <- DMPs$Name
length(all)
[1] 870529
par(mfrow=c(1,1))
gst <- gometh(sig.cpg=sigCpGs, all.cpg=all, plot.bias=TRUE)

I got following error All input CpGs are used for testing. Error in getMappedEntrezIDs(sig.cpg = sig.cpg, all.cpg = all.cpg, array.type = array.type, : There are no genes annotated to the significant CpGs

or if I mention array.type = "EPICv2" then I get All input CpGs are used for testing. Error in h(simpleError(msg, call)) : error in evaluating the argument 'x' in selecting a method for function 'grepl': $ operator is invalid for atomic vectors

or if I use minfi created object annEPICv2 <- getAnnotation(IlluminaHumanMethylationEPICv2anno.20a1.hg38) then error is All input CpGs are used for testing. Error in strsplit(ann.keep$UCSC_RefGene_Group, split = ";") : non-character argument

plz help resolve this issue.

missMethyl has now been updated to support the EPICv2 array for the BioC 3.20 release. To access the functionality now please install the development version of missMethyl.

Hi, currently the gene set testing functionality in missMethyl doesn't support EPICv2. It's on the to-do list. Cheers, Belinda
