I'm a Knime noob so apologies if my question is a really basic one:
I have a long dataset of "distances" between pairs of entities, effectively an unpivoted distance matrix:
Entity1, Entity2, Distance
A, B, 0.2
A, C, 0.4
B, C, 0.5
I'd like to hierarchically cluster this data.
I had expected the "Hierarchical Clustering (DistMatrix)" node to do this but the "Distance matrix column" is disabled (and I don't have anything connected to input port1).
I'm sure this must be an easy one.
Please can anyone suggest a solution?
