Hi,

I'm trying to read Illumina idats with crlmm in R, and I get this error:

Error in quantile.default(M, c(1, 5)/6, names = FALSE)

I have found multiple posts about this issue, but none of them seems to provide a general answer:

In a couple of those links, there are answers suggesting that this is due to small sample sizes, but n=100 in one post, and in my case, n=36. This is the complete output I get in R:

thedata <- genotype.Illumina(cdfName="humanomni25quadv1b", call.method='krlmm')

Any ideas? Thanks a lot,
