ChipQC doesn't run

Question

[francesca3]

Hi everyone, I'm having troubles with ChipQC.

I load the samplesheet and I try to run the ChIPQC function but several errors appears:

chipObj<-ChIPQC(samples, annotation="mm9")

Bam file has 22 contigs
Error: BiocParallel errors
  element index: 1, 2, 3
  first error: don't find the function "seqlevels<-"
 Warning messages:
1: In serialize(data, node$con) :
  'package:stats' could not be available during the loading

Anyone can help?

Thanks
Francesca

I found the problem. There is a bug when the package is used from PC. It needs to launch this command register(SerialParam()) before launching the CHIPQC command
