Error in serialize(data, node$con) : error writing to connection

[brindavjk]

Hi,

I got the following error while trying to run BISCUIT_main.R on my dataset:

Error in serialize(data, node$con) : error writing to connection

It looks like it specifically occurs during the BISCUIT_IMM_Gibbs_MCMC_parallel.R step at lines 593-604:

for(r_all in 1:runs.all){

print(paste("Beginning of batch ",r_all));

results.per.MCMC <- foreach(r=((1+(num_gene_sub_batches*(r_all-1))):(num_gene_sub_batches*r_all)),.packages=c("Rtsne","lattice","MASS","bayesm","robustbase","chron","mnormt","MCMCpack", "coda","Matrix", "mvtnorm")) %dopar% {
    values <- list()
    values <- main.fun(r)
    return(list(unlist(values[[1]]),unlist(values[[2]]),unlist(values[[3]]),values[[4]],values[[5]],values[[6]])) ##z, alpha, beta, mu and Sigma
}
results.all.MCMC[[r_all]] <- results.per.MCMC
print(paste("End of batch ",r_all));

}

It looks like it may be related to a cluster failing because of memory? It happens at gene batch 15. I used the numCores <-detectCores()-1 feature. And is there any way to solve this?

Thank you
