Default Error in mvnX when running processSamples.R of OncoCNV


I tried to run (most recent version) on a set of 9 normal sample alignments to generate a baseline to call CNVs on a set of 8 tumor samples. I used an appropriate tab-delimited BED file (chr, start, end, amplicon ID, 0, and gene name), BAM alignments, and an Ensembl reference genome. All tool requirements were satisfied. However, I was getting the following error with processSamples.R:

running processSamples.R
Package 'mclust' version 5.4.5

PSCBS v0.65.0 successfully loaded. See ?PSCBS for help.

In addition: Warning messages:

4: In rnorm(length(autoInd), 0, sdError[autoInd]) : NAs produced

I want to mention that the Control.stats.Processed.txt file from processControls.R contained some fields with missing values (NA) for mean and IC1-3. Replacing those values with arbitrary numbers did not seem to help. Any clues as to what could be causing this error would be much appreciated.

Thank you!
