Hello everyone, I am attempting to run the sample commands given in the CRLMM version 2 vignette. After loading the crlmm library and hapmapsnp6 library I have run the following commands: Jenna's R> path <- system.file("celFiles", package="hapmapsnp6") Jenna's R> celFiles <- list.celfiles(path, full.names=TRUE) Jenna's R> system.time(crlmmResult <- crlmm(celFiles, verbose=TRUE)) Loading required package: genomewidesnp6Crlmm Welcome togenomewidesnp6Crlmmversion 1.0.4 Loading annotations and mixture model parameters. Processing 3 files.  |==================================================| 100% Loading annotations. Determining gender. Calling 906600 SNPs for recalibration... Done. Estimating recalibration parameters. Calling 906600 SNPs... Done.   user  system elapsed 281.242   7.256 298.400 Warning message: In crlmmGT(res[["A"]], res[["B"]], res[["SNR"]], res[["mixtureParams"]],  :  Recalibration not possible. Possible cause: small sample size. After I get this when I attempt to look at the results, using crlmmResult[["calls"]][1:10, ] I get NULL. There are no results anywhere in crlmmResults.  I have tried running this with both hapmapsnp5 and hapmapsnp6.

Hi Jenna, can you please point me to the vignette you're looking at? The proper way of accessing the genotype calls is: theCalls = calls(crlmmResult) Similarly, if you need access to the confidence scores: theConfsProb = confs(crlmmResult) ## probability scale theConfsIntg = confs(crlmmResult, FALSE) ## "integer" scale - uses less RAM benilton On 17 August 2011 16:56, Jenna Cameron <jcamer7 at="" uwo.ca=""> wrote: > Hello everyone, > > I am?attempting?to run the sample commands given in the CRLMM version 2 vignette.
