Hi, has anyone worked with data from the new Illumina Epic dataset? It has over 850K vs 450K. I tried using methyAnalysis but getting errors because there does not seem to be any annotation packages like the IlluminaHumanMethylation450k.db.

This is my first time doing methylation analysis; so I'm stuck. Does anyone know what other packages/technique I can use to get around this annotation problem? I do not have the IDAT files but outputs from genomestudio as provided by our vendor. I could possibly get the IDAT files though if it helps.

Thank you in advance.

Hi Ahdee,

An annotation package for the MethylationEPIC array will be available in the next Bioconductor release (scheduled for April 15). In the meantime, you can test out the current version that is available from https://bitbucket.org/khansen/illumina_epic.

Peter, this is awesome. Stupid question but I see two files, one is a manifest file? Do I just download and install this as usual with install.packages function? Thanks.

Would I also be able to use this with other packages like lumi: for example lumiMethyR requires an annotation IlluminaHumanMethylation450k.db, can I do something like, lumiMethyR("input.txt",lib="IlluminaHumanMethylationEPICanno.ilmn10.hg19") instead? thanks.

There are two packages on that webpage. Install them as you install any other source tarball (I do R CMD INSTALL from the command line).

I don't know off hand whether it works out-of-the-box with lumi. Perhaps give it a try and report back with how you go.

I followed your posts and tried to load it in lumi, and got the error:

rawdata <- lumiMethyR("MethylationProfile.txt",lib="IlluminaHumanMethylationEPICanno.ilm10b2.hg19")

Error in match(x, table, nomatch = 0L) : object 'allAnnotation' not found

I am extremely new to the analysis. Any idea? Thank you.
