Troubleshooting error with BSmooth: `error in serialize(data, node$con)`

Question

[Jautis]

Hello, I'm trying to run BSmooth (from the bsseq package) and encounting an error that says Error in serialize(data, node$con) : error writing to connection. It looks like this error is usually associated with parallelization, but I can't figure out how to deal with it. Any suggestions?

Thank you in advance!

Code:

myobj <- BSseq(pos = rawdata$start[rawdata$chr == "chr19"], 
      chr = rawdata$chr[rawdata$chr == "chr19"], 
      M = as.matrix(mat_M[rawdata$chr == "chr19",]), 
      Cov = as.matrix(mat_cov[rawdata$chr == "chr19",]))

smobj <- BSmooth(myobj)
