Hi,

I am getting an error tying to run GENIE3 on an single cell RNA seq expression matrix (15121x6477 numeric matrix):

> weightMatrix <- GENIE3(exprMatrix_filtered, regulators=inputTFs, nCores=24)
Error in do.call("%dopar%", list(obj, ex), envir = parent.frame()) : 
  could not find function "%dopar%"

I would appreciate help with this.

Resolved. Did not realize %dopar% is in the foreach package. foreach was not loaded; once it is, GENIE3 works.
