I’m checking this example “04_Quality_Control” with the HCS-Tools.
When i run the node Z-Primes (PC x NC) i’ve got a warning / error on the console:

WARN Z-Primes (PC x NC) 3:8 too few samples (4)while calculating standard-deviation/mad for attribute: Count_PIobjects (Mean)
ERROR Z-Primes (PC x NC) 3:8 too few samples while calculating mean-statistic for attribute Count_PIobjects (Mean)

Could you give us an example that works. In fact, this example works, just there is a warn, but the z-Primes are well calculated.

Sorry for this post !
