I am new to analyzing array data and I am currently trying to analyze some 850k array data using minfi. I have loaded the IlluminaHumanMethylationEPICmanifest and IlluminaHumanMethylationEPICanno.ilm10b2.hg19. I am following this "recipe": A cross-package Bioconductor workflow for analysing methylation array data. The read.metharray.exp()
function works (and everything else down to the point of normalisation) and i manage to assign the right annotation. However, many downstream functions like qcReport()
, preprocessQuantile()
, preprocessNoob()
, preprocessFunnorm()
give me an error:
[preprocessQuantile] Mapping to genome. Error in `assayDataElement<-`(`*tmp*`, "Meth", validate = FALSE, value = c(471, : unused argument (validate = FALSE) In addition: Warning message: display list redraw incomplete
I cannot seem to figure out what the problem is, i have also tried to use the 450k annotation as well but it still does not work.
It would also be helpful if you would show the code you used up to that point.
