simulateDE() error

[Yale73]

Hi powsimR team,

I am interested in our package and play around with our single cell data. We subset two conditions and one cluster to check the DEG power. I follow our vignette. All the steps work fine, but I ran the following error on simulateDE() step. Can you help me?

simres <- simulateDE(SetupRes = setupres,
                      Prefilter = NULL, Imputation = NULL,
                      Normalisation = 'scran',
                      DEmethod = "MAST", DEFilter = FALSE,
                      NCores = NULL, verbose = TRUE)

Preparing output arrays.

  SIMULATION   NUMBER   1

Generating gene expression.
500 vs. 500
Applying scran normalisation
Using calculateSumFactors, i.e. deconvolution over all cells!
Error: BiocParallel errors
  element index: 1
  first error: missing value where TRUE/FALSE needed
In addition: There were 50 or more warnings (use warnings() to see the first 50)

Thanks,
Yale
