Hi Matt
As it happens this got on the back burner earlier and I am getting
back to
it now. I am getting similar errors trying to do the CNV analysis on
Illumina Omni5 idat files. I would be more than happy to share subset
of
data with you. Just wondering if you would have time now to help with
this.
Depending on the subset of idat files I choose I am getting different
errors.
Example:
#1
leaving out novariant SNPsStart calculating Prior MeansError in
calculatePriorValues(M, numSNP, verbose) :
could not find function "makeCluster"
#2
Instantiate CNSet container.Initializing container for genotyping and
copy number estimationProcessing sample stratum 1 of 1Quantile
normalizing 12 arrays, one at a time.

chol.default(crossprod(sweep(matS, 1, z[, 1], FUN = "*"), matS)) :
