I am relatively new to knime and was wondering how I can get the multivariate Z prime node to work. I am able to have the node execute and complete, but in the box where the multivariate Z prime should be there is simply a ?. I tried many different ways to control my table but am simply unable to generater a multivariate- z prime. Right now, I am grouping by the plateID (I.E. name of experiment) and then subsetting by the treatment column (which just has PC or NC depending on the class the row belongs to). If there is anyway to show me a workflow the node works properly or help me get my data to work that would be tremendously helpful. My data has many more rows than columns as well if that makes a difference.
