Hi,

I am following RnBeads tutorial and with Ziller2011_PLoSGen_450K data set. The tutorial says that the analysis takes 1 1/2 hours on two compute nodes but for me after overnight run with 4 cores it didn't finish so I had to terminate the process. It seems that there is a problem with some part of the job that the script throughs out Warning in cor(x[i[i <= N]], y) : the standard deviation is zero error for unlimited lines. It never ends and I couldn't stop it so I have to terminate whole R session by ending task on windows. Here I provide library(RnBeads) and sessionInfo()output if it can be helpful. I appreciate if someone can help to figure out the problem.
