yes, It is Infinium HumanMethylation27 BeadChip

OK, here's the part I don't understand.  How do you end up with 485000+ features and a 275MB file fromrr just 12 samples on 27k chips?  The information (and the presence of rsXXXXXX probes) strongly suggests that you are dealing with 450k data.  I'm not saying you are wrong, just that it's very strange.  What happens if you run 

addColorChannelInfo <- lumiMethyR(myFile, lib="IlluminaHumanMethylation450k.db")

instead?  Still crashing?


@Vincent
There is no error because all i see the mac - rainbow wheel.. And so I end
up 'force quiting' R without session info.

Can you type 

library(lumi)
library(methylumi)
library(IlluminaHumanMethylation27k.db)  
sessionInfo()

and paste the result into an email?  It might be possible for me to reroduce your error with that information.

Thanks!
