This package provides the manifest for the Illumina Human Methylation MSA array, based on the csv available on their support site .
The script used to generate the manifest can be found in /tmp/RtmpchNlsT/Rinste1a27760ec7d/IlluminaHumanMethylationMSAmanifest/scripts/manifest.R.
Curently minfi
will not automatically identify the array correctly, so this must be set by hand. As an example:
read.metharray.exp(...)
RGset <-annotation(RGset) <- list(array = "IlluminaHumanMethylationMSA",
annotation = "10a1.hg19")
After setting the annotation, you can then process the RGset
as normal.
