When I used ChIPQC, I followed the manuals to construct a sample sheet (name is "examplefile.csv"), and then run:

>a <- read.csv("examplefile.csv")

>b = aa = ChIPQC(a, annotation=NULL)

Computing metrics for 16 samples...
Error in (function (nnodes = getOption("mc.cores", 2L), ...)  :
  'nnodes' must be >= 1

 

When I use the same "examplefile.csv" file for DiffBind analysis, it works very well.

So, I don't know why the ChIPQC doesn't work.

Any help would be appreciated!!
