Ok, so I thought I got past getting stuck using discretization, as I have used it many times, but i am stuck. I have looked at my prior processes and the samples and I am not sure what I am doing wrong. It will not discretize...

    Hi sukotto,

    did you just forget to connect the Discretize operator to a result output?

    I remodel you process with other data and it works (btw, you do not need the numerical to real operator):
