[BioC] crlmm problem

[Aaerp]

Hi all,

I am trying to analyze some Illumina beadarray SNP data 
(humanomniexpress12v1b) using crlmm. Do you have any thoughts on what 
might be happening here?

Kind regards,
Agusti

library(ff)

datadir <- "/Volumes/My Passport/SNP_LGG/6182351100"
samplesheet = read.csv(file.path(datadir, 
"SampleSheet_PJ1111109_11S46v2.csv"), header=TRUE, as.is=TRUE,sep="\t")

arrayNames <- file.path(datadir, unique(samplesheet[, "SentrixPosition_A"]))

all(file.exists(paste(arrayNames, "_Grn.idat", sep="")))
#[1] TRUE
all(file.exists(paste(arrayNames, "_Red.idat", sep="")))
#[1] TRUE
cdfName <- "humanomniexpress12v1b"
batch <- rep("1", nrow(samplesheet))
arrayInfo <- list(barcode=NULL, position="SentrixPosition_A")

cnSet <- genotype.Illumina(sampleSheet=samplesheet,
arrayNames=arrayNames,
arrayInfoColNames=arrayInfo,
cdfName="humanomniexpress12v1b",
batch=batch)
