Use of the IlluminaHumanMethylationMSAmanifest

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:

RGset <- read.metharray.exp(...)
annotation(RGset) <- list(array = "IlluminaHumanMethylationMSA",
                          annotation = "10a1.hg19")

After setting the annotation, you can then process the RGset as normal.
