Hi

I am using sigcheck package to validate my signature I run these codes

library(breastCancerNKI)
library(SigCheck)
data(nki)
data(knownSignatures)
nki <- nki[,!is.na(nki$e.os)]
check <- sigCheck(nki, classes="e.os", survival="t.os",signature=mysignature,annotation="HUGO.gene.symbol",validationSamples=which(nki$series=="NKI2"))
nkiResults <- sigCheckAll(check, iterations=1000)

but I get this error: 

Error: stop worker failed:
 'clear_cluster' receive data failed:
 reached elapsed time limit
