Dear all, I am trying to use BeadExplorer to load Illumina Mouse8 arrays for analysis. I used the latest BeadStudio software version to generate expression data, but it actually does not give summary files such as gene.profile.csv and qcinfo.csv, so I had to save them separately when I opened the data. Here the error I constantly get when I load the data: > data<-beadAnalysis() Read C:/Program Files/R/R-2.4.0/data/mouse_copy_sample_gene_profile.csv Normalised data... Generated qc data... Error in sum(detExprs(beadData)[, i] > value) : subscript out of bounds In addition: Warning message: no non-missing arguments to min; returning Inf There are no header lines when I save my data directly from BeadStudio. Does it matter?
