Thanks for your quick reply, very much appreciated. I think I have it working correctly in parallel now, but I'm still a bit confused and would like to confirm if possible. Here is my main function, which is similar to the CRMAv2 vignette except modified to be run either in single CPU mode or by

I would also like to run segmentation in parallel, but how do you do this if you are using a separate reference set. This is what I am running in a single process (that I would like to parallelize): cbs <- CbsModel(cesN, reference) ce <- ChromosomeExplorer(cbs) process(ce, chromosomes = 1:23, z
