Sanity Check problem

Dear all,

I receive the following error message while trying to perform a SanityCheck:

Create objects for storing processed data

mSet<-InitDataObjects(“pktable”, “mf”, FALSE)
mSet<-SetDesignType(mSet, “multi”)

Loading the data table and the metadata

mSet<-Read.TextDataTs(mSet, “xxx.csv”, “rowmf”);
mSet<-ReadMetaData(mSet, “xxx_metadata.csv”)
mSet<-SanityCheckData(mSet)
Error in if (ncol(int.mat) == 1) { : argument is of length zero

I have double-checked: both data files are .csv. I guess this error also hampers further normalization.

I’d be grateful for help.

Thank!
