Finding Sentrix ID in HM450K arrays

Question

[Betul]

Hello everyone, I downloaded a methylarray dataset from GEO but unfortunately it doesn't contain Sentrix ID. I checked the .idat file but there is only sentrix position info but not ID. I tried to person who uploads the dataset but the email address in not valid anymore. How can you figure out these kind of problems? Thanks in advance

##Using R, illuminaio from Bioconductor     

library(illuminaio)
temp.idat <- readIDAT(file = "200379120087_R02C02_Grn.idat")
temp.idat$Barcode
